Which pathogen is notably linked to diarrhea from uncooked burgers?

E. coli O157:H7 is a specific strain of the bacterium Escherichia coli that is associated with foodborne illness, particularly from consuming undercooked or contaminated ground beef, such as uncooked burgers. This pathogen is known for producing Shiga toxin, which can lead to severe gastrointestinal symptoms, including bloody diarrhea, abdominal cramps, and, in some cases, hemolytic uremic syndrome.

In contrast, while Salmonella can cause gastrointestinal illness from undercooked poultry, eggs, and sometimes beef, it is not as strongly associated with ground beef as E. coli O157:H7. Bacillus cereus typically results in food poisoning due to rice and starchy foods, while Vibrio is more related to contaminated seafood. The distinctive link of E. coli O157:H7 with raw or undercooked beef makes it the primary concern related to burger preparation.
