Micro-organisms living on food: plan and do (non-statutory)

Mould is a micro-organism. It is a type of fungus and can be grouped with other fungi including yeast and mushrooms. Mould is common in moist materials and food, such as fruit, bread, cheese and meat. Mould needs moisture, warmth and nutrients to grow well. Mould can be observed growing on food over time, following strict safety rules. Scientists make predictions about what will happen based on the evidence they already have.
