Yersinia is primarily linked to which type of food?

Yersinia, specifically Yersinia enterocolitica, is primarily associated with raw or undercooked foods, with ground pork being one of the most notable sources of this pathogenic bacteria. This bacterium can cause yersiniosis, a foodborne illness characterized by symptoms such as diarrhea, abdominal pain, and fever. Ground pork is often not cooked to a sufficiently high temperature to kill the bacteria, which makes it a significant vehicle for transmission.

Other foods listed, such as oysters, leafy greens, and smoked fish, may be linked to different pathogens or foodborne illnesses. For instance, oysters are more commonly associated with Vibrio bacteria, leafy greens might carry E. coli or Salmonella, and smoked fish can be problematic due to Listeria. However, when it comes to Yersinia, ground pork stands out as the primary food linked to this pathogen, highlighting the importance of proper cooking practices to ensure food safety.
