He's had malaria, bilharzia (a tropical disease caused by parasitic worms picked up from snails), leishmaniasis (a parasitic disease spread by the bite of a sandfly), roundworm, botflies and ringworm.
Some things, however, are virtually unrecognizable once they've been frozen and thawed. In other words, you can freeze whatever you want, and use these foods frozen, but some foods don't hold up after being defrosted. Here are 11 things you should not keep in the freezer. Freezing food is a delicate matter. No matter what you're freezing, make sure to use it within nine months or so (yes, that means cleaning out your freezer), and also make sure to defrost it correctly.
Freezing has very little effect on the nutrient content of foods. Some fruits and vegetables are blanched (immersed in boiling water for a short period) before freezing to inactivate enzymes and yeasts that would continue to cause food spoilage, even in the freezer.This process can cause some of the vitamin C (15 to 20%) to be lost.xamples of foods that do not tolerate freezing well include salad vegetables, mushrooms and soft fruits. Foods with higher fat contents, such as cream and some sauces, tend to separate when frozen. Commercial freezing rapidly freezes foods so that smaller ice crystals are formed.
