Moulds on food

Some moulds can cause allergic reactions and respiratory problems and some in the right conditions, produce 'mycotoxins', which are poisonous substances that can make people sick. 

Moulds can grow at temperature as low as 2 degrees centigrade in a refrigerator.

To find out more information about moulds and whether it is safe to eat food when you see mould on it, see the article 'Moulds On Food: Are They Dangerous?' which is at  the USDA's Food Safety Focus website.
