Food poisoning Bacteria & Virus

1.      Bacillus cereus

Ingestion of food contaminated with Bacillus cereus or toxins produced by this organism is responsible for foodborne illness. Bacillus cereus produces enterotoxins. It causes food poisoning of two types: diarrheal type, which is characterized by abdominal pain and watery diarrhea; and emetic type which is manifested by profuse vomiting.
2.      Campylobacter jejuni (but also C. fetus, Campylobacter coli)

5.      E.coli 0157:H7 (Enterohemorrhagic E. coli)
6.      Listeria monocytogenes
7.      Salmonella Typhimurium and S. Enteritidis
8.      Shigella spp
Shigellosis is also known as bacillary dysentery. Most cases are caused by Shigella sonnei. However, S. dysenteriae, S. flexneri and S. boydii can also cause foodborne related illnesses.
9.      Staphylococcus aureus
Staphylococcus aureus makes seven different toxins that are frequently responsible for food poisoning.
10.  Vibrio cholerae
Vibrio choleare produces cholera toxin. Which is an enterotoxin, responsible for profuse watery diarrhea (also termed as rice watery stools).
11.  Yersinia enterocolitica
Parasites
