Does Salmonella produce spores or toxins?

Answer 1

Salmonella, Campylobacter, hemorrhagic E. coli and Listeria all cause infections.
Food intoxication results from consumption of toxins (or poisons) produced in food by bacterial growth.
Toxins, not bacteria, cause the illness. Toxins may not alter the appearance, odor or flavor of food.
After ingestion. the vegetative cells start to sporulate in the intestinal tract (change their life form into spores) and release the toxin.
Salmonella produces spores in the GI tract. The spores release the toxin causing the illness called food poisoning.

Answer 2

According to the FDA Bad Bug Book, Salmonella spp.are non-spore formers, so - no spores.

There are two types of illnesses caused by Salmonella: nontyphoidal salmonellosis and typhoid fever. In both types, route of entry is the same in that the bacteria is ingested orally (contaminated food & water, fecal particles, etc). Both work their way into the epithelium of the small intestine, where inflammation starts by the nontyphoidal type. With typhoid fever, the bacteria works its way into the blood stream to other organs where inflammation starts. There is evidence enterotoxin may be produced by both types.

Historically, Salmonellosis has been called a food infection, not a food intoxication, because the illness is caused by ingesting live bacteria and not a toxin.

Answer 3

No. The only anaerobic spore formers belong to the genus Clostridium
