The Growing Threat of Foodborne Bacterial Enteropathogens of Animal Origin

Abstract

Campylobacter and Salmonella species and Shiga toxin-producing Escherichia coli (STEC; the majority of which are type O157:H7) efficiently enter the human food chain from infected or colonized animals. Poultry contamination with Campylobacter and/or Salmonella species and produce contamination with STEC have become major public health challenges. The global food supply, which allows us to purchase desired items throughout the year, a growing interest in consuming fresh vegetables and fruits, and an increasing number of persons who consume foods at restaurants all assure that the health threats associated with these pathogens will continue. Antibiotic use by humans and food animals selects for the development of resistance among Campylobacter and Salmonella strains, promoting invasive forms of infection and complicating therapy of illness. A comprehensive public health approach is needed that focuses on disease surveillance and infection control in the food industry continuum, from harvesting and processing, to distribution, to later preparation in public eating establishments and in homes. Good Agricultural Practices, including the Hazard Analysis and Critical Control Point Program and validation of critical infection-control points at all stages of the food industry cycle, coupled with other food safety interventions, including irradiation for certain higher-risk foods, should help us improve the quality of food with regard to microbials and reduce human disease.

Bacteriophages of Clostridium perfringens

“…This has resulted in the general public's perception that antibiotic use by humans and in food animals selects for the development of AMR among food-borne bacteria that could complicate public health therapies (DuPont, 2007). A major issue is that antibiotic resistance may not only occur among disease-causing organisms but also become an issue for other resident organisms in the host which may accumulate in the environment (Yan & Gilbert, 2004).…”

Advances in Soybean and Soybean By-Products in Monogastric Nutrition and Health

“…As with soymilk and soymilk based products, post-production contamination of soybean products is a potential health hazard. Ikuomola and Eniola (2010) Harris et al, 2003;DuPont, 2007). Water used for soy sprouts should be potable and free of foodborne pathogens.…”

Joint Opinion on antimicrobial resistance (AMR) focused on zoonotic infections

“…The emergence of MDR Salmonella with additional resistance to third-generation cephalosporins, such as S. Typhimurium DT104 and S. Newport-MDR-AmpC, is responsible for most of the increase in cephalosporin resistance in the EU and elsewhere (DuPont, HL, 2007;Gupta, A et al, 2003;Threlfall, EJ, 2000)). In Europe and North America, S. Enteritidis PT4 has also been reported as MDR with increasing frequency (Gupta, A et al, 2003;Threlfall, EJ, 2000;Whichard, JM et al, 2007).…”
