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

AI Thread Summary
Food preservation is crucial for preventing the growth of dangerous bacteria that can lead to foodborne illnesses. Common pathogens include Salmonella and Staphylococcus, which can thrive in specific conditions such as improper food handling and storage. These bacteria can multiply rapidly, especially in warm, moist environments, and even a small number of cells can pose a significant health risk. Once ingested, these bacteria can survive stomach acid and typically infect the intestines, leading to symptoms like diarrhea. The body reacts to bacterial growth by expelling the pathogens through diarrhea, which is a defense mechanism to eliminate harmful invaders. Understanding these aspects of food safety is essential for effective food preservation and reducing the risk of foodborne illnesses.

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?
