Gereffi, Scott et al. Tomato Best Management Practices require Florida packers to treat tomatoes in a flume system containing at least 150 ppm of free chlorine or other approved sanitizer. However, research is needed to determine the ability of these sanitizers to prevent the transfer of pathogens from contaminated to uncontaminated tomatoes, particularly under realistic packinghouse conditions.

Torso, Lauren M. et al. Escherichia coli O157:H7 is a common cause of foodborne illness in the United States. Beef ground at establishments regulated by the U.S. Department of Agriculture, Food Safety and Inspection Service is routinely tested for E. coli O157:H7. Prior to December 2013, boxed beef product (wholesale cuts of beef, such as beef loin, packaged into bags and boxed for shipping) was not always tested for this pathogen.

Evans, Nicholas P. et al. Salmonella is an important economic and public health concern for the poultry industry. Fresh ground product has been linked with multiple salmonellosis outbreaks in humans. Exposure can be controlled by proper handling and preparation by consumers; however, the industry desires to minimize carriage levels in the final product. A substantial obstacle in reducing product contamination stems from limitations in diagnostic methodologies.

Bowman, Lauren S. et al. Salmonellosis has been increasingly associated with contaminated spices. Identifying inoculation and stabilization methods for Salmonella on whole spices is important for development of validated inactivation processes. The objective of this study was to examine the effects of inoculation preparation on the recoverability of Salmonella enterica from dried whole peppercorns and cumin seeds. Whole black peppercorns and cumin seeds were inoculated with S.

Brooks, Brian W. et al. Non-O157 enterohemorrhagic Escherichia coli in priority serogroups O26, O45, O103, O111, O121, and O145 are increasingly recognized as important human pathogens. In the present study, a panel of monoclonal antibodies (MAbs) to the lipopolysaccharide O antigens of E. coli in serogroups O26, O45, O103, O111, O121, and O145 was produced. The specificity was evaluated by examining the reactivity of the MAbs with 50 E. coli strains and 42 non–E.

Lydon, Keri Ann et al. Raw oyster consumption is the most common route of exposure for Vibrio spp. infections in humans. Vibriosis has been increasing steadily in the United States despite efforts to reduce the incidence of the disease. Research has demonstrated that ice is effective in reducing postharvest Vibrio spp.

Kiermeier, Andreas et al. Australia exports about 150,000 to 200,000 tons of manufacturing beef to the United States annually. Each lot is tested for Escherichia coli O157 using the N-60 sampling protocol, where 60 small pieces of surface meat from each lot of production are tested. A risk assessment of E.

Saiyudthong, S. et al. A multiplex PCR assay for simultaneous detection and differentiation of Campylobacter jejuni, Campylobacter coli, and Campylobacter lari was developed and validated to assess the occurrence of these bacteria in fresh chicken meat and by-products in Bangkok, Thailand, by using a new combination of four previously published PCR primers for C. jejuni, C. coli, C. lari, and a universal 16S rDNA gene as an internal control.

Sharma, C. S. et al. The efficacy of the recently approved Salmonella lytic bacteriophage preparation (SalmoFresh) in reducing Salmonella enterica serotype Heidelberg on turkey breast cutlets and ground turkey was evaluated. In a broth model assay, the phage preparation completely inhibited the growth of four S. enterica serotypes (Salmonella Enteritidis, Salmonella Heidelberg, Salmonella Kentucky, and Salmonella Typhimurium) at 37°C at a multiplicity of infection of 10,000 PFU/CFU.

The objectives of study were to assess presence of Listeria monocytogenes, perform serotyping and investigate antibiotic resistance in raw milk and dairy products. A total of 210 milk and dairy products including white (n = 20) and kashar cheese (n = 20), ice cream (n = 20), butter (n = 20), cokelek (n = 10), kuymak (n = 10) and farm cheese (n = 10) were obtained from Samsun, Turkey.
