The bacterial species most commonly associated with GI infection and infectious diarrhea in the United States are Shigella spp., Salmonella spp., Campylobacter spp., Yersinia spp., Escherichia spp., Clostridium spp., and Staphylococcus spp. 

Yersiniabactin (Fig. 23, 69) was obtained from Yersinia spp., and is produced also by Pseudomonas syringae 49) and Escherichia coli (7 78). Its structure was elucidated independently by two groups and given the names yersiniabactin (96)... 

Yersinia spp. are non-lactose-fermenting gram-negative coccobacilli that are widely distribnted in natnre. The genns Yersinia includes six species known to cause disease in humans. The best known species is Y pestis, the causative agent of plague, which is usually spread by bites from infected animals, such as fleas, rodents, or cats. Y. enterocolitica and, to lesser extent, Y. pseudotuberculosis are most likely associated with intestinal infection, but overall, both are a relatively infrequent cause of diarrhea and abdominal pain. More than 50 serotypes of Y. enterocolitica exist of these, serotypes 0 3, 0 8, and 0 9 are associated most frequently with enterocolitis. Infections are reported commonly from northern Europe, and the peak incidence occurs during the winter months.

Refrigeration of sous-vide products is the other major concern. If heat treatment is ineffective then Listeria and Yersinia spp. that can grow at refrigeration temperature can proliferate (Table 6.3). Prolonged refrigeration under these circumstances could pose a serious health hazard.
