Answer 1

Adding to the previous good answers. Bacteria can also produce toxic substances. Bad body odour for example comes from acid produced by bacteria living on your skin and hair. Killing the bacteria doesn’t remove the toxic substances.

That is why you can still get ill even if you boil spoiled food.
