The analysis of pesticide residues in fruit, vegetables, rape seed and water has been improved using developments in sample handling and analytical techniques. The method development is associated with analytical difficulties, since pesticides currently used in agriculture represent a variety of chemical classes having very different physico chemical properties. The method development also encounters difficulties when many various commodity classes with different characteristics are studied. The main task in pesticide residue analysis has been to provide multi residue methods, and traditionally GC has been the main analytical technique.. In order to regulate the use of hazardous pesticides, the EU commission introduces strict maximum residue levels (MRL). The need for improved sample handling and detection techniques are, however, high due to handling of lower detection limits, complex matrices and the need of more efficient sample throughput. Of the new techniques introduced as alternative ...

The prototypical xenoestrogen o,p′-dichlorodiphenyltrichloroethane (o,p′-DDT) acts by binding and activating the estrogen receptor (ER). The present study focuses attention on the mechanisms through which another organochlorine compound, β-hexachlorocyclohexane (β-HCH), exerts estrogen-like effects in human breast cancer cells. Both o,p′DDT and β-HCH stimulated proliferation in a dose-dependent manner in the ER-positive cell lines MCF-7 and T47D but not in the ER-negative lines MDA-MB231, MDA-MB468, ...
Pesticide residues on the food we eat are highly regulated. Although some residues may remain at the time of harvest, residues tend to decline as the pesticide breaks down over time. In addition, as the commodities are washed and processed prior to sale the residues often diminish further. There are several steps consumers can take to further reduce any pesticide residue that may remain on your food after purchase.. Consumers may also choose to purchase organic foods, which are grown and processed without synthetic pesticides and fertilizers..

Figure 3: Number of confirmed food poisoning outbreaks and affected persons that were causedby consumption of pesticide-contaminated vegetables, 1988 - 2016 (Source: Centre for Health Protection, Department of Health). The outbreaks before 1996 were mainly caused by the pesticide methamidophos, which was a popular pesticide used in leafy vegetables imported at that time due to its availability and effectiveness in controlling chewing and sucking insects. The methamidophos levels that were commonly found in food poisoning cases at that time were about 200 ppm, which was so high that consumption of a small amount of the vegetable concerned would cause acute symptoms such as nausea, vomiting, abdominal pain, dizziness and blurred vision. Much effort had been made to curb the influx of vegetables that contained dangerous level of pesticide residues. With close liaison with the Mainland authorities and introduction of various control measures, the situation was gradually under control. The setting up ...

Pesticides can remain in the environment for decades and contaminate surface water that is used for irrigation of produce. This study examined pesticide residues in some surface waters and foods in Louisiana. Samples of 8 foods (tomato, corn, rice, blueberry, cucumber, cabbage, wheat and melon) and 35 surface waters were studied using a QuEChERS extraction method for food samples and liquid-liquid extraction method for the water samples. Gas chromatography-mass spectrometry was used to analyze water and food samples. Nine pesticides were detected in the surface water samples and 5 in the food samples. Pesticides detected in foods were below FDA tolerance limit but 0.18 ppm cypermethrin found in tomato was within 90% of the FDA limit (0.2 ppm). Four water samples had atrazine levels that were above the FDA limit for potable water. This study suggests the need to intermittently monitor pesticide contamination in our food and water.
Apples and celery this week. Cilantro a couple back. Stories about pesticide residues on food are making the rounds again. After my umpteenth media call, a blog seemed in order. As I told the LA Times, heres my basic response: Its the farmers, farmworkers and residents of rural communities who are really most at risk from pesticides, not consumers. While these folks are exposed to pesticides from food like the rest of us, they also must contend with pesticide fumes drifting out of fields, exposure from working directly with pesticides, and pesticide-coated dust and dirt tracked into their homes from the fields. Tom Philpott, newly migrated to MotherJones, nails this topic.
The aim of the study was to investigate exposure levels of organochlorine pesticides (OCPs) in mothers milk and in selected staple foods. The study also aimed to evaluated effects of 1,1,1-trochloro-2-bis-(4-chlorophenyl)ethane (DDT) on paracetamol half-life in highly exposed and least exposed breast-feeding mothers as a way of investigating possible drug interaction. This was an experimental study where milk and food samples from Esigodini, Harare, Kadoma Kariba Nyanga and Mudzi were collected and analysed for OCPs levels using GC-ECD. Evaluation of induction of the hepatic cytochrome P450 enzymes by DDT was carried out by pre-treatment of female rats with a single intraperitoneal dose of DDT (0.3 mg/g) body weight. Cytochrome P450 enzyme was quantified by potassium phosphate buffering the microsomal fraction followed by spectral determination of the reduction of cytochrome P450. Blood samples from selected mothers in areas showing results of higher exposure levels to DDT and selected mothers ...

For the current study, researchers collected additional information on each womans typical diet, including how often they consumed certain foods, beverages, and supplements over the past year. To measure the impact of pesticide residues in these foods on reproductive success, scientists used the Pesticide Residue Burden Score (PRBS). Using information from the U.S. Department of Agricultures Pesticide Data Program, which tracks pesticide residue on foods sold in the U.S., fruits and vegetables were categorized into distinct PRBS categories, ranging from one -being the least contaminated, to six -being the most contaminated. (See Table 1 in the study, or to the right for the PRBS of each fruit and vegetable.). Results show, after adjusting for a range of confounders, that women who eat more conventional fruits and vegetables (more than 2.3 servings per day) with a score of 4 or above on the PRBS had a 18% lower probability of clinical pregnancy and a 26% lower chance of live birth. However, ...

The results show that all three QuEChERS methods perform very well, but AOAC Official Method 2007.01 was found to give better overall results. It is also somewhat ...
The high-throughput analysis of pesticides has been hindered by slow and laborious sample preparation. This application note evaluates a new approach using an innovative laboratory tissue homogenizer to extract various pesticide residues from different kinds of plant materials and to identify and quantify active ingredients by LC/MS/MS.
Pesticides are widely used by farmers to control pests, weeds and molds that would otherwise decrease crop production. While this has significantly increased worldwide food productions, these same pesticides pose significant health and environmental risks and are therefore subject to increasing regulation. Since many different types of pesticides can be used on the same food product, multi-residue screening approaches are used. This application note details the Zebron MultiResidue™ col

Pesticide suicide refers to toxic chemicals mucking up the health of animals, plants and insects. This worldwide causatum may be totally out of control or maybe not; nobody knows for sure. Therein lies the scary part.
In the interest of food safety, pesticide residue testing is done in many countries for both domestically produced and imported agricultural products. Baby food is an area of high interest due to the ramifications of exposing infants and young children to toxins, especially during the critical years of brain and nervous system development. Limiting exposure to pesticides is considered critical in maintaining a safe, healthy diet. In the United States, tolerance limits for agricultural products that could be used for producing baby food are set by the USEPA. Testing of these commodities is then performed by the USDA under its annual Pesticide Data Program (PDP). Baby food, in particular, has been included in testing conducted since 2010, with the last round conducted in 2013.1 The European Union (EU) has set maximum residue limits of 4 to 8 μg/Kg for several pesticides in baby food, and specifically listed others as prohibited for use entirely in the production of agricultural products ...

The U.S. Senate is finally preparing to ratify the Stockholm Convention, a global treaty banning persistent organic pollutants (POPs). Legislation now moving through Congress, however, deeply undermines the agreement by allowing the U.S. to ignore international decisions targeting new chemicals under the treaty. Reducing the treatys effectiveness is no way to ratify, tell your Senators to adopt the Stockholm Convention at full strength.. The Stockholm Convention was signed by more than 100 countries in 2001, and has now been ratified by 35 of the 50 nations needed to bring the treaty into effect. The Convention was developed to eliminate a class of particularly dangerous chemicals that are toxic, move great distances via wind and water, persist in the environment and bio-accumulate as they move up the food chain. The treaty will immediately ban 12 POPs, nine of which are pesticides once used widely in the United States.. The treaty includes provisions for taking future action on additional ...

The need to protect crops from pests and damage dates back millennia. In recent decades, pesticides have emerged as the most effective method of control. With pesticide use comes a need to manage their wider effects. One key area of importance is ensuring that safe maximum residue levels (MRLs) are agreed on and monitored globally for food and feed products. Governments setting MRLs have someway to go before any harmonized approach is implemented worldwide. Therefore, it is imperative companies involved in food and feed goods are proactive and vigilant in understanding and meeting MRLs requirements in their chosen markets.. ...

Journal of Association of Official Analytical Chemists International. 88.pp. 615-629. Interpretive Summary: Pesticide residue analysis of foods is a main function of many analytical laboratories around the world. The current methods used in analysis are time-consuming, laborious, and expensive. A quick, easy, cheap, effective, rugged, and safe (QuEChERS) method for analysis of pesticide residues in food was recently introduced to provide a much more efficient way to better meet laboratory needs. However, a few problematic pesticides remained in the method, and this study demonstrates how the use of buffering in the procedure solves the problems associated with sample preparation of these pesticides. Excellent results were obtained for notoriously difficult-to-detect pesticides. This buffered ...

Food testing laboratories worldwide are responsible for checking the presence of regulated pesticide residues on food products because these chemicals can be harmful to health and the environment. These laboratories have traditionally relied on gas chromatography coupled with mass spectrometry (GC-MS) for rapid and reliable pesticide detection in large sample numbers. However, changing regulations and increasingly diverse pesticides are driving the need for alternative liquid chromatography tandem mass spectrometry (LC-MS/MS)- based methods for comprehensive screening.
EDGE Application Note Abstract The QuEChERS method has been shown to be practical for pesticide analysis on a number of different sample types and is increasingly being employed on more difficult matrices.  Unfortunately, this process is a manual multi-step process that can be time consuming. With so many different types of food matrices and pesticide residues to be analyzed there is a need for a faster simplified extraction method. Furthermore, some matrices either by their nature or their economic value, can be difficult to analyze with just the QuEChERS method alone. In this application note we propose the EDGE™ as an alternative to the QuEChERS method for the extraction of pesticides from food matrices including known difficult matrices. With its patent pending Q-Cup Technology™ the EDGE can extract a difficult food sample, including the dispersive solid phase cleanup, in less than 5 minutes in one automated
In order to assess the trend in the body load of organochlorine pesticide residues in Great Britain, between July 1965 and June 1967 samples of fat were taken during routine necropsies on 247 subjects over 3 years old and on 44 stillborn or premature babies and infants below the age of 3. The levels of the three main pesticides, B.H.C., dieldrin, and D.D.T., were lower than those found in an earlier survey carried out in 1963 and 1964. No marked differences were observed in levels throughout Britain, but the levels in man were higher than those in women. Britain compares favourably with other countries in which similar surveys have been done.. ...
The European Food Safety Authority (EFSA) has presented new methodology for grouping pesticides that will allow the implementation of cumulative risk assessment for studying the risks posed by exposure to multiple pesticide residues.. The EFSA methodology is based on classifying pesticides into cumulative assessment groups (CAGs) on the basis of exhibiting similar toxicological properties in a specific organ or system. The method has already been used to define groups of pesticides toxic to the thyroid and central nervous systems.. Traditional methods of risk assessment for pesticide residues have looked at individual compounds in isolation, but current EU law now requires that assessments study the cumulative effects of exposure to a range of different pesticides simultaneously. This approach allows possible interactions between pesticides to be included in the risk assessment. The new EFSA method paves the way for these cumulative assessments.. The next stage is the gradual implementation of ...

Characterizing dietary pesticide exposures, particularly for infants and children, has become an essential component of cumulative pesticide risk assessment, as mandated by the 1996 FQPA. Several reports (Lu et al. 2006a, 2006b, 2008, 2009; Schettgen et al. 2002) have clearly demonstrated the significant contribution of dietary intakes to the overall OP and pyrethroid pesticide exposure in children and highlighted the critical need to quantify the health risks associated with the low but chronic daily exposures to those pesticides. As the result of the 1993 NRC report, the U.S. Congress funded the PDP under the USDA to test pesticide residues annually in foods consumed most often by children and, to the extent possible, as eaten. Since its inception, PDP has tested , 200,000 food commodity samples for an extensive list of pesticides. When pesticide residues reported in the PDP database are combined with food consumption information, such as those surveyed in the Continuing Survey of Food ...

Pesticides are widely used chemicals that are impossible for most of us to avoid. Many people are aware that they impact weeds, insects, and fungi - as they are designed to do. But it is widely believed that they are harmless to humans at the low doses that they are exposed to through their diet.. However, a study published last year[1] in the Journal of the American Medical Association (JAMA) suggests that pesticide residues in food may account for a large proportion of the roughly 100,000 unsuccessful pregnancy attempts in fertility clinics across North America.. The women in the study were grouped according to the amount of pesticides they ingested, as indicated by US Department of Agriculture data on average pesticide residue levels found in common foods. The study found that the women in the highest quartile (the 25% of women who consumed the most pesticides) had a 26% reduced chance of having a live birth than women in the lowest quartile, who consumed the least amount of pesticides. These ...
Propamocarb (PM) is one of the main pesticides used for controlling cucumber downy mildew. However, due to its volatility and internal absorption, PM can easily form pesticide residues on cucumber fruits that seriously endanger human health and pollute the environment. The breeding of new cucumber varieties with a low abundance of PM residues via genetic methods constitutes an effective strategy for reducing pesticide residues and improving cucumber safety and quality. To help elucidate the molecular mechanism resulting in a low PM residue abundance in cucumber, we used the cucumber cultivar D0351 (which has the lowest PM residue content) as the test material and identified genes related to low PM residue abundance through high-throughput tag-sequencing (Tag-Seq). CsMAPEG was constitutively expressed and showed both varietal and organizational differences. This gene was strongly expressed in D0351. The expression levels of CsMAPEG in different cucumber tissues under PM stress were as follows: fruit
According to Article 12 of Regulation (EC) No 396/2005, the European Food Safety Authority (EFSA) has reviewed the maximum residue levels (MRLs) currently established at European level for the pesticide active substance cymoxanil. In order to assess the occurrence of cymoxanil residues in plants, processed commodities, rotational crops and livestock, EFSA considered the conclusions derived in the framework of Directive 91/414/EEC as well as the European authorisations reported by Member States (incl. the supporting residues data). Based on the assessment of the available data, MRL proposals were derived and a consumer risk assessment was carried out. Although no apparent risk to consumers was identified, some information required by the regulatory framework was missing. Hence, the consumer risk assessment is considered indicative only and some MRL proposals derived by EFSA still require further consideration by risk managers ...
According to Article 12 of Regulation (EC) No 396/2005, the European Food Safety Authority (EFSA) has reviewed the maximum residue levels (MRLs) currently established at European level for the pesticide active substances sodium 5-nitroguaiacolate, sodium o-nitrophenolate and sodium p‑‑nitrophenolate. In order to assess the occurrence of resulting residues in plants, processed commodities, rotational crops and livestock, EFSA considered the conclusions derived in the framework of Directive 91/414/EEC as well as the European authorisations reported by Member States (incl. the supporting residues data).

1. Always Wash Produce Under Running Water. In the course of growing fruits and vegetables, most cultivators spray pesticides on the leaves and stems to protect the crop from luring damage. With this, a considerable amount of pesticides also accumulates on the outer surface of the grown fruits and vegetables.. The best option to remove the harmful toxic residue is to wash your produce under running warm water (rather than very cold or hot water) before putting it on your dish.. Make sure you dont just quickly rinse and wipe the produce as the pesticides do not simply dissolve in the water. Actually, it is the action of rubbing produce under tap water that helps remove the residue.. Fruits like tomatoes, grapes, apples, strawberries, guava, blueberries, plums, peaches and pears, as well as veggies like eggplants, green beans and okra, can be cleaned properly using this easy method.. You should be thorough when washing the mentioned fruits and vegetables and, if needed, you can opt for 2-3 ...
Adopting dual standards is a practice large multi national corporations follow especially when it comes to developing countries. Soft drinks industry is a classic case of this as the Centre for Science and Environment (CSE) discovered way back in 2003. A laboratory report prepared by CSE detailed some astonishing facts about the extent of pesticide contamination in soft drinks sold in India.. CSE found high levels of toxic pesticides and insecticides, high enough to cause cancer, damage to the nervous and reproductive systems, birth defects and severe disruption of the immune system. Market leaders Coca-Cola and Pepsi had almost similar concentrations of pesticide residues. At the same time CSE also tested two soft drink brands sold in the US, to see if they contained pesticides. They didnt. This only goes to show the companies were following dual standards.. These startling facts forced the government constitute a Joint Parliamentary Committee, only the fourth in post independent India and the ...

THE OWNER OF THE ESTABLISHMENT IS RESPONSIBLE TO MAKE SURE ADEQUATE TRAINING IS PROVIDED TO BOTH WORKERS AND HANDLERS. A worker has certain legal rights under the WPS program. These include the right to be informed about pesticide use that may affect the work environment, the right to receive WPS training, and the right to ask questions without fear of reprisal.. For workers exposed to pesticide residues on plants with which they are working, WPS training must include the following eleven items:. ...
POP History. The Stockholm Convention on Persistent Organic Pollutants (POPs) was adopted in May 2001 and entered into force in May 2004. [1] This is a global treaty to protect human health and the environment by eliminating the use POP chemicals, or restricting the production and use of these chemicals.. In May 2001, the EU signed the Stockholm Convention. [2] This was ratified in November 2004 and entered into force in February 2005. This commitment at the Union level was published under Regulation (EC) No. 850/2004 [3] on POPs. This regulation has been amended on many occasions, including setting a limit for short chain chlorinated paraffins (SCCPs) in articles [4] in 2015. Amending European Regulation Of Persistent Organic Pollutants. On March 2, 2016, the EU published Regulation (EU) 2016/293 [5] amending Regulation (EC) No 850/2004 of the European Parliament and of the Council on persistent organic pollutants prohibiting the manufacture, placing on the market and use of HBCDD.

Demand for organic foods is partially driven by consumers perceptions that they are more nutritious. However, scientific opinion is divided on whether there are significant nutritional differences between organic and non-organic foods, and two recent reviews have concluded that there are no differences. In the present study, we carried out meta-analyses based on 343 peer-reviewed publications that indicate statistically significant and meaningful differences in composition between organic and non-organic crops/crop-based foods. Most importantly, the concentrations of a range of antioxidants such as polyphenolics were found to be substantially higher in organic crops/crop-based foods, with those of phenolic acids, flavanones, stilbenes, flavones, flavonols and anthocyanins being an estimated 19 (95% CI 5, 33) %, 69 (95% CI 13, 125) %, 28 (95% CI 12, 44) %, 26 (95% CI 3, 48) %, 50 (95% CI 28, 72)% and 51 (95% CI 17, 86)% higher, respectively. Many of these compounds have previously been linked to ...
Pesticides work by interfering with an essential biological mechanism in the pests, but because all living organisms share many biological mechanisms, pesticides are never specific to just one species. While pesticides may kill pests, they may also kill or harm other organisms that are beneficial or at least not undesirable. They may also harm people who are exposed to pesticides through occupational or home use, through eating foods or liquids containing pesticide residue, or through inhaling or contacting pesticide-contaminated air. The ideal pesticide would be highly specific to only the target organism, be quick acting, and would degrade rapidly to harmless, inert materials in the environment. ...
The study reported in Environmental Health Perspectives focused on the impact of in-utero exposure to organophosphate pesticides among more than 300 Mexican-American children in the agricultural Salinas Valley in California. The children were checked at age three-and-a-half, and then again at age five. Researchers measured the quantities of breakdown products from these pesticides in the mothers urine twice during pregnancy. Then they looked at the children to see if there was evidence of ADHD symptoms. They found that the children whose mothers had higher levels of pesticide products during pregnancy were much more likely to exhibit ADHD symptoms by age five, and this was especially true for boys. According to study member Amy Marks, a research analyst at the University of California School of Public Health in Berkeley, It is worth looking at this more carefully and conducting more research on this topic, since low-level exposure to pesticides and pesticide residues in food is quite common. ...
The Accredited Laboratory Program accredits nonfederal analytical chemistry laboratories to analyze meat and poultry food products for moisture, protein, fat, and salt (MPFS) content, and/or certain specific classes of chemical residues. Currently the specific chemical residues are chlorinated hydrocarbons (CHC), polychlorinated biphenyls (PCB), sulfonamides, nitrosamines, and arsenic.
A large variety of insecticides, herbicides, and fungicides are widely used in agriculture to increase yield, control microorganisms that may produce toxic or carcinogenic metabolites, and reduce the price of food production. Such pesticides are intended to kill living organisms, and a potential dose-related acute and chronic toxicity exists in humans with an estimated 800 000 cases of acute intoxications each year worldwide, including some 3000 deaths.1 2 The use of pesticides and their acceptable maximum concentration in foods therefore need to be regulated. Of particular concern is the exposure of infants and children to food contaminants because of their possible increased susceptibility for adverse effects.3-5 In this article we wish to comment from a paediatric perspective on the choices, which have recently been debated, for defining reliably safe maximum residue limits for pesticides in dietary foods for infants and young children in the European Union.. The directives of the European ...
By: Chumba Koech. Abstract. The rapid advancement of technology and agriculture practices in the United States has shaped the landscape of the country. In an attempt to increase production yields, the development of pesticides led to its nation-wide use. While increasing production yields, little was known about pesticides adverse effects on human health. The primary objective of this paper is to examine the role of pesticides in agriculture and their effect on obesity and type 2 diabetes. This paper presents evidence that pesticides are detrimental to human health because pesticides disrupt metabolic homeostasis, predisposing individuals to gain weight. From this information, it can be concluded that the usage of pesticides in the United States needs to be reduced. In examining the detrimental effects of pesticides, alternative solutions have been proposed. Permaculture, a human and environment friendly model, presents practices that eliminate the need for the pesticides used in our country. In ...
New York, NY , Posted on March 26th, 2012. Using nanoparticles made of pure gold, Dr. Dan Peer, head of Tel Aviv Universitys Laboratory of Nanomedicine at the Department of Cell Research and Immunology and the Center for Nanoscience and Nanotechnology, with a team including Drs. Meir Goldsmith and Dalit Landesman-Milo and in collaboration with Prof. Vincent Rotello and Dr. Daniel Moyano from the University of Massachusetts at Amherst, has developed a new method of introducing chemical residues into the immune system, allowing them to note the properties that incur the wrath of immune cells. Because the gold flecks are too small to be detected by the immune system, the immune system only responds when they are coated with different chemical residues ...
Three years have passed since the day we released our first study on pesticides. The government reduced excise duty on soft drinks in this years budget.. The market is looking up. But the standards recommended were blocked by powerful interests in the government. The CSE team presents the inside story. Our world changed a little when we published the study on pesticide residues in soft drinks. In the work we do, fights go with the territory. We need to challenge institutions -- government and private -- in the public interest. What we had not anticipated, however, was the sheer power and the virulence of the attack. The fact is that the two companies affected -- Coca-Cola and PepsiCo -- were incidental to our story on pesticide contamination and the need for food standards to regulate safety. The fact that two us multinationals were involved was a mere coincidence. But not for them ...
Conventional farming techniques have incorporated chemical pesticides for many years. In the beginning it was believed that these pesticides were the only way to maintain high crop yields. Not much thought was given early on to the cumulative dangers of these poisons as they were continuously being fed into the earth. Pesticides can cause serious environmental problems. Many pesticides are highly toxic to aquatic life. Pesticide pollution can be driven by rainfall, with contamination of rivers and groundwater occurring from water draining off land or infiltrating to the water table. We are concerned about pesticide residues in water and the effects of pesticides on wildlife. The increased use of pesticides is one aspect of a general intensification of agriculture over the past fifty years. As a consequence of the increased use of pesticides, the number of farmland birds has declined. Evidence suggests that certain pesticides that find their way into water can interfere with endocrine (hormone) ...
The Australian Pesticides and Veterinary Medicines Authority (APVMA) has before it an application from DuPont (Australia) Limited to vary the label approval of this product to include use on leafy vegetables, nashi pears and table grapes. This involves approving a varied product label and the establishment of Maximum Residue Limits for food commodities (MRLs) for indoxacarb.
