Compact Dry(R) X-BC for the enumeration of Bacillus cereus in food samples.
(58/107)
We evaluated the effectiveness of using Compact Dry(R) X-BC (CD-XBC), a ready-to-use and self-diffusing dry medium sheet culture system based on a novel detection principle, for the detection and enumeration of Bacillus cereus. All 13 B. cereus strains, which were studied for the inclusivity study, grew as blue/green colonies on the CD-XBC. When 3 yeast strains and 103 bacterial strains other than B. cereus were tested for the exclusivity study, 5 strains formed white colonies, and 4 strains formed blue/green colonies, while 94 other strains failed to grow. The 4 strains that formed blue/green colonies were B. thuringiensis, which is known to have the same biochemical features as B. cereus. The CD-XBC method was compared with the MYP agar method (MYP) and the NGKG agar method (NGKG) in 130 artificially contaminated food samples. The correlation coefficients between CD-XBC and MYP, and CD-XBC and NGKG were 0.972 and 0.971, respectively. (+info)

New food safety initiatives in the Food Safety and Inspection Service, U.S. Department of Agriculture.
(60/107)
The production of meat and poultry products has become increasingly complex. Technological growth has contributed to the need for sophistication in determining the origin and risk of food-borne microbial infections as well as environmental contaminants. The increasing use of agricultural chemicals in animal production and to some extent in processed foods has led to the presence of chemical residues in meat and poultry. These changes have caused the Food Safety and Inspection Service (FSIS), a public health agency within the United States Department of Agriculture (USDA), to institute new food safety initiatives and procedures for inspection of meat and poultry products. The goal is to reduce risks to the public health from conditions observed during antemortem and postmortem inspection or detected during processing. FSIS is committed to scientific innovation and has implemented several rapid inplant tests that have given the Agency inexpensive, less disruptive methods to determine product adulteration contamination.

New data in France on the trematode Alaria alata (Goeze, 1792) obtained during Trichinella inspections.
(61/107)
The trematode Alaria alata is a cosmopolite parasite found in red foxes (Vulpes vulpes), the main definitive host in Europe. In contrast only few data are reported in wild boars (Sus scrofa), a paratenic host. The aim of this paper is to describe the importance and distribution of Alaria alata mesocercariae in wild boars, information is given by findings of these larvae during Trichinella mandatory meat inspection on wild boars' carcasses aimed for human consumption. More than a hundred cases of mesocercariae positive animals are found every year in the East of France. First investigations on the parasite's resistance to deep-freezing in meat are presented in this work. (+info)

Food safety epidemiology capacity in state health departments--United States, 2010.
(63/107)
In 2002, the Council of State and Territorial Epidemiologists (CSTE) conducted its first national food safety epidemiology capacity assessment, which provided the basis for development of minimum performance standards to guide state and local foodborne disease control programs. During April 2010, CSTE sent states a follow-up, web-based questionnaire to gather information about food safety-related workforce training and education, epidemiology and laboratory capacity, and information technology (IT) to support surveillance. This report summarizes the results of the assessment, which found that in 2010, states reported a need for 304 more full-time equivalent (FTE) employees working in food safety to reach full program capacity, with the greatest demand for master's degree-level epidemiologists (50% of demand). Barriers to investigating foodborne outbreaks reported most often by states included delayed notification of the outbreak (reported by 41 states), lack of a sufficient number of foodborne safety staff members (29 states), lower prioritization of investigations (27 states), lack of ability to pay overtime (20 states), and lack of adequate epidemiology expertise (12 states). Strategies should be developed to increase the number of food safety staff members and enhance their training opportunities, address gaps in IT, and improve the relationship between state and local health departments and federal agencies collaborating on responses to foodborne disease outbreaks.

Microbiological baseline study of beef and pork carcasses from provincially inspected abattoirs in Alberta, Canada.
(64/107)
In 2006 and 2007 beef and pork carcass swabs from provincially inspected abattoirs in Alberta, Canada were tested to determine the levels of total aerobic bacteria, coliform bacteria, and generic Escherichia coli, and the prevalence of Salmonella spp., Campylobacter spp., and Shiga toxin-producing E. coli (STEC). Swabs from beef and pork carcasses from 48 and 34 facilities, respectively, were analyzed. All samples tested were positive for aerobic bacteria with 99.8% of beef and 96.0% of pork samples, having total counts of +info)
