Cause
Coli
Coli bacteria are found in the intestines of people and animals. Most varieties are harmless, but some strains — such as E. coli O157:H7 — secrete a toxin that can cause abdominal cramps, vomiting, and bloody Diarrhea. Spread through contaminated water or food that came into contact with animal manure. E. coli can also spread through direct person-to-person contact.
Salmonella
Salmonella infection is commonly caused by eating raw or undercooked poultry, meat, and eggs. The majority of salmonella infections can be classified as gastroenteritis.
Viral
Norovirus. Noroviruses are the most common cause of foodborne illness worldwide. It’s especially likely to spread among people in confined spaces. Although in most cases the virus is spread through contaminated food or water, person-to-person transmission is also possible
Cryptosporidiosis
A leading cause of waterborne disease in the United States, Cryptosporidium is a microscopic parasite which causes cryptosporidiosis. It has an outer shell that helps it survive outside of a host and tolerate chlorine disinfection.
