Bill Marler has been involved in most major foodborne illness outbreak lawsuits in the US over the past 20 years.
He says there are a few things that you should definitely avoid if you want to avoid being sick.
Firstly, stay away from raw or uncooked eggs and, while you're at it, keep away from raw milk too. Some people think the term 'unpasteurised' means more nutrients. But, in actual fact, it just means more bacteria.
Raw shellfish such as oysters are also problematic. According to Marler they have caused more sickness in the past five years than they have in the last 20.
He blames this on rising water temperatures which produce more bacteria.
Thirdly - and this might upset a few people - Marler says he only eats red meat if it's well-done.
Pre-cut and pre-washed vegetables at the supermarket are also risky. In fact any meal you haven't prepared yourself could put you at risk of picking up a sickness bug.
Finally, avoid uncooked sprouts - such as bean, alfalfa, clover and radish sprouts - as these can harbour E. coli and salmonella.
Conversely, one thing that Marler says is safe to munch on is sushi. Who knew?
