8) Once food has been cooked, all the bacteria have been killed The possibility of bacterial growth actually increases after cooking, because the drop in temperature allows bacteria to thrive. 9 ...
Botulism can occur in several ways. The bacterial spores which cause it are common in both soil and water and are very resistant. They produce the botulinum toxin when exposed to low oxygen levels and certain temperatures. Foodborne botulism happens when food containing the toxin is eaten.
Depending on the type of botulism considered, different tests for diagnosis may be indicated. Foodborne botulism: serum analysis for toxins by bioassay in mice should be done, as the demonstration of the toxins is diagnostic. [62] Wound botulism: isolation of C. botulinum from the wound site should be attempted, as growth of the bacteria is ...
Botulism is nevertheless known to be transmitted through canned foods not cooked correctly before canning or after can opening, so is preventable. [144] Infant botulism arising from consumption of honey or any other food that can carry these spores can be prevented by eliminating these foods from diets of children less than 12 months old. [147]
The U.S. Centers for Disease Control and Prevention studied 2007 data and reviewed a total of 1,097 food borne disease outbreaks that led to 21,244 illnesses and 18 deaths. Salmonella and ...
They can also be found in eggs, milk, and meat from animals that have been contaminated during their feeding process. [37] Since they are resistant to high temperatures and physical and chemical reception, it is considered unavoidable while cooking at high temperatures.

The vegetative cells of clostridia are heat-labile and are killed by short heating at temperatures above 72–75 °C (162–167 °F). The thermal destruction of Clostridium spores requires higher temperatures (above 121.1 °C (250.0 °F), for example in an autoclave ) and longer cooking times (20 min, with a few exceptional cases of more than ...
