Apparently cutting the mould of cheese for example is ok, but eating mouldy meat, fish, fruit, veg is risky. Read something, something due to the different pathogen and surface versus infiltration of the cells
Shouldn't wash chicken apparently, cooking kills anything nasty and you're more likely to spread it around the kitchen
I go on taste and smell, I am suspicious of out of date chicken curry ready meals even though the meat is already cooked, because you can't smell or taste if it's off as easily. I got campylobacter from a chicken show mein from a takeaway, I thought it tasted a little off but was a different place to usual. Nasty for a few weeks, needed antibiotics, had to be reported to the communicable disease people!
