Which bacterium causes yersiniosis with incubation 3-7 days and is associated with pork and chocolate milk?

Yersinia enterocolitica is the bacterium that causes yersiniosis, and it typically has an incubation period of about 3–7 days. It is classically associated with pork products and, in some outbreak scenarios, with chocolate milk, making this combination a strong clue for its involvement. The illness often presents with diarrhea and abdominal pain, and can resemble other gastrointestinal infections, which is why the specific food associations help distinguish it. Brucellosis, caused by Brucella, is linked to unpasteurized dairy products or contact with infected animals and tends to cause a longer, undulating fever and systemic symptoms rather than a gastrointestinal illness centered on pork or dairy. Clostridium perfringens causes rapid-onset food poisoning, typically within 8–16 hours, and is more often connected to improperly stored meats or gravies, not specifically pork with chocolate milk or a 3–7 day incubation. Vibrio parahaemolyticus is mainly associated with seafood, especially raw or undercooked shellfish, and not with pork or chocolate milk. So the described incubation and food associations point to Yersinia enterocolitica as the cause.
