They may still be blown apart into little fragments, no longer held together by a nice cell membrane (like popping a balloon)..
Is it safe to eat food left out for 4 hours?
Leaving food out too long at room temperature can cause bacteria (such as Staphylococcus aureus, Salmonella Enteritidis, Escherichia coli O157:H7, and Campylobacter) to grow to dangerous levels that can cause illness. … If the temperature is above 90 °F, food should not be left out more than 1 hour.
Can bacteria survive cooking and reheating?

Most foodborne bacteria and viruses can be killed when food is cooked or reheated long enough at sufficient high temperature. The core temperature of food should reach at least 75℃. … Cook with strong heat rather than low heat.
Will 400 degrees kill bacteria?
Foods at temperatures between 40 degrees and 140 degrees are perfect hosts for bacteria to multiply–rapidly enough so that foods left out longer than 2 hours are unsafe to eat. … Bacteria will not multiply but may start to die between 140 and 165 degrees. Bacteria will die at temperatures above 212 degrees.
Is it OK to eat meat that smells a little?

Does cooking old food kill bacteria?
Boiling does kill any bacteria active at the time, including E. coli and salmonella. But a number of survivalist species of bacteria are able to form inactive seedlike spores. … After a food is cooked and its temperature drops below 130 degrees, these spores germinate and begin to grow, multiply and produce toxins.
