How to avoid contracting food poisioning from restaurants and takeaways ?

Wrong forum: There is no answer to this question other than not to eat in such places. Perhaps you can contact your public health officials where you live for a list of questionable places in your community.

Food poisoning: Use good hygiene, avoid handling of food by infected people, avoid use of unpasteurized milk, insure that drinking water is clean. Many foods should not sit out at room temperatures for very long prior to consumption. May wish to avoid street vendors or meats/ poultry that are inadequately cooked.
