High protein foods such as meat, poultry, fish and eggs are most commonly associated with Salmonella. However, any food that becomes contaminated and is then held at improper temperatures can cause salmonellosis. Salmonella are destroyed at cooking temperatures above 150 degrees F.
What bacteria grows on cooked food?
After a food is cooked and its temperature drops below 130 degrees, these spores germinate and begin to grow, multiply and produce toxins. One such spore-forming bacterium is Clostridium botulinum, which can grow in the oxygen-poor depths of a stockpot, and whose neurotoxin causes botulism.
Can bacteria grow on food that is safely cooked?
Food that is being cooked or reheated should hit 74°C (or 165°F). … Between 4°C and 60°C (or 40°F and 140°F) is the “Danger Zone.” Keep food out of this temperature range because bacteria will multiply rapidly. Between 0°C and 4°C (or 32°F and 40°F), most bacteria will survive but will not multiply quickly.

At what temperature does bacteria grow on meat?
Temperature needs to be considered for bacterial growth. Bacteria like temperatures between 40 and 140 degrees Fahrenheit, and this is known as the Temperature Danger Zone (TDZ). They grow even more rapidly when kept at temperatures from 70 F and 125 F, so you must limit the time foods stay at these temperatures.
