Which food is NOT commonly associated with Yersinia enterocolitica?

Yersinia enterocolitica is primarily linked to specific types of food, notably dairy products, certain meats, and occasionally shellfish. In this case, the food most commonly associated with the bacterium includes raw milk, which can be contaminated during the milking process. Meats, particularly those that are undercooked or handled improperly, are also recognized as potential sources.

Poultry, while it can harbor various pathogens, is generally not strongly associated with Yersinia enterocolitica compared to the other options. This particular bacterium is more often linked to pork and dairy. Oysters, particularly raw ones, can sometimes act as vectors for Yersinia, but poultry does not have the same level of common association with this pathogen as the other food items listed. Thus, poultry stands out as the option not regularly related to Yersinia enterocolitica.
