It's generally not recommended to eat mouldy food as it can be harmful to your health. However, some foods can be salvaged if the mould is limited to a small area.
You can cut off the mouldy part plus an extra inch and still consume the rest.
Mold can be cut away from items like carrots, bell peppers, and cabbage.
Surface mould can be scrubbed off before consumption.
You can trim the mouldy edges on firm bread, but it's best to discard if it's a soft or moist type.
Mold is part of the fermentation process for foods like sauerkraut and miso, so a thin layer on the surface is usually safe to scrape off.
Always exercise caution and use your best judgement. When in doubt, it's safer to discard mouldy food.
