Which bacteria infect our food? What are their growth rates? Harmful levels?

  1. Sep 11, 2012 #1
    I'm curious about food preservation. Which are the most common dangerous bacteria? How quickly do they grow? What sort of conditions? And how many must be present to pose a threat to a human?

    Also, how do they survive the stomach? Do they infect via the mouth or esophagus?

    You mean like samonella or staph in eggs? that kind of thing

    The bacteria that cause diarrhea survive stomach just fine. Their site of action usually happen at the intestine level.

    Yes, I'm interested in any/all food pathogens.

    Do you know how/why the body reacts to bacterial growth with diarrhea?
