If I cut off the mouldy part of cheese or jam, can I safely eat the rest?

Answer

No. According to the Ministry, cutting off the mouldy part does not mean the rest is safe. Especially in foods with high water content, mould can spread into the interior in ways invisible to the eye, and some species can produce heat-resistant toxins (mycotoxins). For this reason the Ministry recommends that products such as yoghurt, jam, tomato paste and bread be discarded entirely, not partly consumed, once mould appears.
