When you're going on a picnic, don't take food out of the fridge until the last minute and use a cool bag to keep it chilled until you're ready to eat. It's especially important to keep the following foods cool:
- food containing cream, such as trifle, cream cakes and desserts
- meat and poultry
When you're eating outdoors you should also remember to keep food covered whenever possible - this is to protect it from insects, birds and pets, which can carry bacteria.
