Best before' labels going on pre packed fruit and veg. No one gets sick from eating rotten fruit and veg, fortunately.
This isn't true weirdly. I'm always quite cavalier about lettuce etc until DH told me off. He works in an area involving food liability payouts and says lettuce, Vegetables and leafy greens are a common source of food poisoning, especially those eaten raw.
Fruit and veg cause a lot of the food poisoning outbreaks, particularly lettuce, celery and tomatoes.
Vegetables and leafy greens can become contaminated with harmful bacteria, such as E. coli, Salmonella and Listeria. This can occur across various stages of the supply chain.
"Contamination can occur from unclean water and dirty runoff, which can leach into the soil that fruits and vegetables are grown in."
"It can also occur from dirty processing equipment and unhygienic food preparation practices. Leafy greens are especially risky because they are often consumed raw ."
In fact, between 1973 and 2012, 85% of the food poisoning outbreaks in the US that were caused by leafy greens such as cabbage, kale, lettuce and spinach were traced back to food prepared in a restaurant or catering facility.
