Mycotoxin dangers

Mould growing on food or on the walls of damp houses may contain mycotoxins. Exposure to mycotoxins can cause breathing problems and fever; long-term exposure may cause chronic problems such as cancer, lupus and mental retardation.

2

Mild effects

More mild effects of eating mouldy bread include an upset stomach, nosebleeds, headaches, diarrhoea and flu-like symptoms.

3

Lung problems

Mould also can cause respiratory problems or allergic reactions if the spores are inhaled.

4

Mould growth

Mould on bread and other foods can survive in cold temperatures. It will grow roots deep into the bread, so cutting off visible mould or removing a few mouldy pieces from a loaf will not protect you from toxins.

5

Mould disposal

Dispose of mouldy bread carefully, outside the house if possible. Wear gloves and a face mask to avoid handling or inhaling spores, disinfect areas where the mould grew and throw out any food that may have been cross-contaminated.
