Survey of the incidence of Aeromonas and Yersinia species in retail foods

摘要: Abstract A total of 520 samples foods were purchased from six major retailers and tested for the presence Aeromonas hydrophila (and related species) Yersinia enterocolitica species). Overall, species isolated 10.8% 4.2%, respectively, tested. The isolation rate was dependent on food type these bacteria obtained most frequently fresh (raw) meats (32–57% samples) dressed salads (20% samples). With species, contamination other types (i.e. fish, salads, sandwiches, milk dairy products) 1–5% except desserts, soft cheeses bottled water, which no isolates made. Foods, than those above, commonly > 10%) fish salads. Isolates Y. not considered to be potentially pathogenic as determined using in vitro tests. Several agar plating media and/or enrichment broths used both microorganisms. No single procedure able recover all either genus.
