Automated food microbiology: potential for the hydrophobic grid-membrane filter. (1/3560)
Bacterial counts obtained on hydrophobic grid-membrane filters were comparable to conventional plate counts for Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus in homogenates from a range of foods. The wide numerical operating range of the hydrophobic grid-membrane filters allowed sequential diluting to be reduced or even eliminated, making them attractive as components in automated systems of analysis. Food debris could be rinsed completely from the unincubated hydrophobic grid-membrane filter surface without affecting the subsequent count, thus eliminating the possibility of counting food particles, a common source of error in electronic counting systems. (+info)Salmonella infections in Norway: descriptive epidemiology and a case-control study. (2/3560)
The epidemiological progression of human salmonellosis in Norway is parallel to trends noted elsewhere in Europe. During the past two decades, the number of reported cases has increased steadily, with a special sharp rise in the early 1980s due to the emergence of Salmonella enteritidis, followed by a levelling off in recent years. However, in contrast to the situation in most other European countries, about 90% of the cases from whom a travel history is available, have acquired their infection abroad. The incidence of indigenous salmonella infections as well as the prevalence of the microorganism in the domestic food chain, are both comparatively low. In 1993-4, a national case-control study of sporadic indigenous salmonella infections was conducted to identify preventable risk factors and guide preventive efforts. Ninety-four case patients and 226 matched population controls were enrolled. The study failed to demonstrate any statistically significant association between salmonellosis and consumption of domestically produced red meat, poultry or eggs. The only factor which remained independently associated with an increased risk in conditional logistic regression analysis, was consumption of poultry purchased abroad during holiday visits to neighbouring countries. A separate analysis of Salmonella typhimurium infections incriminated food from catering establishments and foreign travel among household members, in addition to imported poultry. (+info)An outbreak of viral gastroenteritis associated with consumption of sandwiches: implications for the control of transmission by food handlers. (3/3560)
Although food handlers are often implicated as the source of infection in outbreaks of food-borne viral gastroenteritis, little is known about the timing of infectivity in relation to illness. We investigated a gastroenteritis outbreak among employees of a manufacturing company and found an association (RR = 14.1, 95% CI = 2.0-97.3) between disease and eating sandwiches prepared by 6 food handlers, 1 of whom reported gastroenteritis which had subsided 4 days earlier. Norwalk-like viruses were detected by electron microscopy or reverse transcriptase-polymerase chain reaction (RT-PCR) in stool specimens from several company employees, the sick food handler whose specimen was obtained 10 days after resolution of illness, and an asymptomatic food handler. All RT-PCR product sequences were identical, suggesting a common source of infection. These data support observations from recent volunteer studies that current recommendations to exclude food handlers from work for 48-72 h after recovery from illness may not always prevent transmission of Norwalk-like viruses because virus can be shed up to 10 days after illness or while exhibiting no symptoms. (+info)A general method for selection of alpha-acetolactate decarboxylase-deficient Lactococcus lactis mutants to improve diacetyl formation. (4/3560)
The enzyme acetolactate decarboxylase (Ald) plays a key role in the regulation of the alpha-acetolactate pool in both pyruvate catabolism and the biosynthesis of the branched-chain amino acids, isoleucine, leucine, and valine (ILV). This dual role of Ald, due to allosteric activation by leucine, was used as a strategy for the isolation of Ald-deficient mutants of Lactococcus lactis subsp. lactis biovar diacetylactis. Such mutants can be selected as leucine-resistant mutants in ILV- or IV-prototrophic strains. Most dairy lactococcus strains are auxotrophic for the three amino acids. Therefore, the plasmid pMC004 containing the ilv genes (encoding the enzymes involved in the biosynthesis of IV) of L. lactis NCDO2118 was constructed. Introduction of pMC004 into ILV-auxotrophic dairy strains resulted in an isoleucine-prototrophic phenotype. By plating the strains on a chemically defined medium supplemented with leucine but not valine and isoleucine, spontaneous leucine-resistant mutants were obtained. These mutants were screened by Western blotting with Ald-specific antibodies for the presence of Ald. Selected mutants lacking Ald were subsequently cured of pMC004. Except for a defect in the expression of Ald, the resulting strain, MC010, was identical to the wild-type strain, as shown by Southern blotting and DNA fingerprinting. The mutation resulting in the lack of Ald in MC010 occurred spontaneously, and the strain does not contain foreign DNA; thus, it can be regarded as food grade. Nevertheless, its application in dairy products depends on the regulation of genetically modified organisms. These results establish a strategy to select spontaneous Ald-deficient mutants from transformable L. lactis strains. (+info)Pulsed-light inactivation of food-related microorganisms. (5/3560)
The effects of high-intensity pulsed-light emissions of high or low UV content on the survival of predetermined populations of Listeria monocytogenes, Escherichia coli, Salmonella enteritidis, Pseudomonas aeruginosa, Bacillus cereus, and Staphylococcus aureus were investigated. Bacterial cultures were seeded separately on the surface of tryptone soya-yeast extract agar and were reduced by up to 2 or 6 log10 orders with 200 light pulses (pulse duration, approximately 100 ns) of low or high UV content, respectively (P < 0.001). (+info)Evaluation of accuracy and repeatability of identification of food-borne pathogens by automated bacterial identification systems. (6/3560)
The performances of five automated microbial identification systems, relative to that of a reference identification system, for their ability to accurately and repeatedly identify six common food-borne pathogens were assessed. The systems assessed were the MicroLog system (Biolog Inc., Hayward, Calif.), the Microbial Identification System (MIS; MIDI Inc., Newark, Del.), the VITEK system (bioMerieux Vitek, Hazelwood, Mo.), the MicroScan WalkAway 40 system (Dade-MicroScan International, West Sacramento, Calif.), and the Replianalyzer system (Oxoid Inc., Nepean, Ontario, Canada). The sensitivities and specificities of these systems for the identification of food-borne isolates of Bacillus cereus, Campylobacter jejuni, Listeria monocytogenes, Staphylococcus aureus, Salmonella spp., and verotoxigenic Escherichia coli were determined with 40 reference positive isolates and 40 reference negative isolates for each pathogen. The sensitivities of these systems for the identification of these pathogens ranged from 42.5 to 100%, and the specificities of these systems for the identification of these pathogens ranged from 32.5 to 100%. Some of the systems had difficulty correctly identifying the reference isolates when the results were compared to those from the reference identification tests. The sensitivity of MIS for the identification of S. aureus, B. cereus, E. coli, and C. jejuni, for example, ranged from 47.5 to 72. 5%. The sensitivity of the Microlog system for the identification of E. coli was 72.5%, and the sensitivity of the VITEK system for the identification of B. cereus was 42.5%. The specificities of four of the five systems for the identification of all of the species tested with the available databases were greater than or equal to 97.5%; the exception was MIS for the identification of C. jejuni, which displayed a specificity of 32.5% when it was tested with reference negative isolates including Campylobacter coli and other Campylobacter species. All systems had >80% sensitivities for the identification of Salmonella species and Listeria species at the genus level. The repeatability of these systems for the identification of test isolates ranged from 30 to 100%. Not all systems included all six pathogens in their databases; thus, some species could not be tested with all systems. The choice of automated microbial identification system for the identification of a food-borne pathogen would depend on the availability of identification libraries within the systems and the performance of the systems for the identification of the pathogen. (+info)Campylobacter jejuni--an emerging foodborne pathogen. (7/3560)
Campylobacter jejuni is the most commonly reported bacterial cause of foodborne infection in the United States. Adding to the human and economic costs are chronic sequelae associated with C. jejuni infection--Guillian-Barre syndrome and reactive arthritis. In addition, an increasing proportion of human infections caused by C. jejuni are resistant to antimicrobial therapy. Mishandling of raw poultry and consumption of undercooked poultry are the major risk factors for human campylobacteriosis. Efforts to prevent human illness are needed throughout each link in the food chain. (+info)Cyclospora: an enigma worth unraveling. (8/3560)
In part, Cyclospora cayetanensis owes its recognition as an emerging pathogen to the increased use of staining methods for detecting enteric parasites such as Cryptosporidium. First reported in patients in New Guinea in 1977 but thought to be a coccidian parasite of the genus Isospora, C. cayetanensis received little attention until it was again described in 1985 in New York and Peru. In the early 1990s, human infection associated with waterborne transmission of C. cayetanensis was suspected; foodborne transmission was likewise suggested in early studies. The parasite was associated with several disease outbreaks in the United States during 1996 and 1997. This article reviews current knowledge about C. cayetanensis (including its association with waterborne and foodborne transmission), unresolved issues, and research needs. (+info)Food microbiology is the study of the microorganisms that are present in food, including bacteria, viruses, fungi, and parasites. This field examines how these microbes interact with food, how they affect its safety and quality, and how they can be controlled during food production, processing, storage, and preparation. Food microbiology also involves the development of methods for detecting and identifying pathogenic microorganisms in food, as well as studying the mechanisms of foodborne illnesses and developing strategies to prevent them. Additionally, it includes research on the beneficial microbes found in certain fermented foods and their potential applications in improving food quality and safety.
Microbiology is the branch of biology that deals with the study of microorganisms, which are tiny living organisms including bacteria, viruses, fungi, parasites, algae, and some types of yeasts and molds. These organisms are usually too small to be seen with the naked eye and require the use of a microscope for observation.
Microbiology encompasses various subdisciplines, including bacteriology (the study of bacteria), virology (the study of viruses), mycology (the study of fungi), parasitology (the study of parasites), and protozoology (the study of protozoa).
Microbiologists study the structure, function, ecology, evolution, and classification of microorganisms. They also investigate their role in human health and disease, as well as their impact on the environment, agriculture, and industry. Microbiology has numerous applications in medicine, including the development of vaccines, antibiotics, and other therapeutic agents, as well as in the diagnosis and treatment of infectious diseases.
A medical definition of 'food' would be:
"Substances consumed by living organisms, usually in the form of meals, which contain necessary nutrients such as carbohydrates, proteins, fats, vitamins, minerals, and water. These substances are broken down during digestion to provide energy, build and repair tissues, and regulate bodily functions."
It's important to note that while this is a medical definition, it also aligns with common understanding of what food is.
I'm sorry for any confusion, but "Food Supply" is not a term that has a specific medical definition. It is a more general term related to the availability and distribution of food. However, in a broader public health context, "food supply" can refer to the overall system and infrastructure that provides food to a population, including agricultural practices, food processing, distribution, and accessibility. Ensuring a safe and adequate food supply is an important aspect of public health and preventive medicine.
Microbiological techniques refer to the various methods and procedures used in the laboratory for the cultivation, identification, and analysis of microorganisms such as bacteria, fungi, viruses, and parasites. These techniques are essential in fields like medical microbiology, food microbiology, environmental microbiology, and industrial microbiology.
Some common microbiological techniques include:
1. Microbial culturing: This involves growing microorganisms on nutrient-rich media in Petri dishes or test tubes to allow them to multiply. Different types of media are used to culture different types of microorganisms.
2. Staining and microscopy: Various staining techniques, such as Gram stain, acid-fast stain, and methylene blue stain, are used to visualize and identify microorganisms under a microscope.
3. Biochemical testing: These tests involve the use of specific biochemical reactions to identify microorganisms based on their metabolic characteristics. Examples include the catalase test, oxidase test, and sugar fermentation tests.
4. Molecular techniques: These methods are used to identify microorganisms based on their genetic material. Examples include polymerase chain reaction (PCR), DNA sequencing, and gene probes.
5. Serological testing: This involves the use of antibodies or antigens to detect the presence of specific microorganisms in a sample. Examples include enzyme-linked immunosorbent assay (ELISA) and Western blotting.
6. Immunofluorescence: This technique uses fluorescent dyes to label antibodies or antigens, allowing for the visualization of microorganisms under a fluorescence microscope.
7. Electron microscopy: This method uses high-powered electron beams to produce detailed images of microorganisms, allowing for the identification and analysis of their structures.
These techniques are critical in diagnosing infectious diseases, monitoring food safety, assessing environmental quality, and developing new drugs and vaccines.
Food labeling is the practice of providing written information about the characteristics and contents of food products, typically on the packaging or container in which they are sold. In a medical context, accurate and clear food labeling is essential for individuals with dietary restrictions due to medical conditions such as food allergies, intolerances, or chronic diseases (e.g., diabetes).
Standardized food labeling guidelines help consumers make informed decisions about the foods they consume, allowing them to avoid potential health risks and maintain a balanced diet. Components of food labels often include:
1. Product identity: The name of the food product and its intended use.
2. Net quantity declaration: The amount of the food product contained in the package, expressed in both metric and customary units (e.g., grams or ounces).
3. Ingredient list: A comprehensive list of all ingredients included in the food product, arranged in descending order by weight. This is particularly important for individuals with food allergies or intolerances, as it allows them to identify and avoid specific allergens (e.g., milk, eggs, peanuts).
4. Nutrition facts panel: A standardized format presenting the nutritional content of the food product per serving, including information on calories, total fat, saturated and trans fats, cholesterol, sodium, total carbohydrates, dietary fiber, sugars, protein, and various vitamins and minerals.
5. Nutrient content claims: Voluntary statements made by manufacturers regarding the level of a nutrient in a food product (e.g., "low fat," "high fiber"). These claims must adhere to strict guidelines established by regulatory bodies to ensure accuracy and consistency.
6. Health claims: Statements linking a specific food or food component to a reduced risk of a particular disease or health-related condition (e.g., "a diet rich in whole grains may reduce the risk of heart disease"). Like nutrient content claims, health claims are subject to strict regulatory oversight.
7. Special dietary statements: Labeling statements indicating that a food product is suitable for specific dietary uses or restrictions (e.g., "gluten-free," "kosher," "vegan"). These statements help consumers with special dietary needs quickly identify appropriate food options.
8. Allergen labeling: Mandatory identification of the presence of any of the eight major food allergens (milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, and soybeans) in a food product. This information must be clearly displayed in the ingredient list or as a separate "contains" statement.
9. Warning statements: Required labeling of specific health risks associated with the consumption of certain food products (e.g., "consuming raw or undercooked meats, poultry, seafood, shellfish, or eggs may increase your risk of foodborne illness").
10. Country of origin labeling: Identification of the country where a food product was produced, grown, or packaged. This information helps consumers make informed decisions about their food purchases based on factors such as quality, safety, and environmental concerns.
Food preferences are personal likes or dislikes towards certain types of food or drinks, which can be influenced by various factors such as cultural background, individual experiences, taste, texture, smell, appearance, and psychological factors. Food preferences can also be shaped by dietary habits, nutritional needs, health conditions, and medication requirements. They play a significant role in shaping an individual's dietary choices and overall eating behavior, which can have implications for their nutritional status, growth, development, and long-term health outcomes.
"Food analysis" is not a medical term per se, but it falls under the broader field of food science and nutrition. Food analysis refers to the laboratory methods and techniques used to determine the composition and quality of food products. This can include testing for nutrients (such as proteins, fats, carbohydrates, vitamins, and minerals), contaminants (like heavy metals, pesticides, or allergens), and other components that may affect the safety, quality, or authenticity of food.
The results of food analysis can be used to ensure compliance with regulatory standards, develop new food products, assess the nutritional value of diets, investigate food-borne illnesses, and monitor trends in food consumption. While not a medical definition, food analysis is an important tool for promoting public health and preventing diet-related diseases.
Bacteriology is the branch of biology that deals with the study of bacteria, including their classification, physiology, genetics, and ecology. It is a subset of microbiology, which is the broader field that includes the study of all microorganisms, including bacteria, viruses, fungi, and parasites.
Bacteriologists use various techniques to isolate, culture, and identify different species of bacteria. They also study the interactions between bacteria and their hosts, as well as the role that bacteria play in disease processes. In addition, bacteriology involves research into the development of new antibiotics and other treatments for bacterial infections.
Overall, bacteriology is an important field of study that has contributed significantly to our understanding of infectious diseases and their prevention and treatment.
