Numerous bacteria can cause gastroenteritis, including:

Yeirsinia, found in pork

Staphylococcus, found in dairy products, meat, and eggs

Shigella, found in water (often swimming pools)

Salmonella, found in meat, dairy products, and eggs

Campylobacter, found in meat and poultry

E. Coli, found in ground beef and salads

Bacterial gastroenteritis outbreaks can happen when restaurants serve contaminated food to many people.

Bacterial gastroenteritis symptoms vary depending on the bacteria causing your infection. The symptoms may include:
