can clostridium perfringens spores be killed?

Answer 1

it is very hard, almost impossible to kill C. perfringens spores. However if food is cooked to the right temperature i.e. 140 degrees F or above, this can help prevent the spores from becoming activated. Once the food is cooked it should not be kept at room temperature and should be chilled as soon as possible
