Outdoor barbecues, carnival food, and camping trips make food a potential breeding ground for illness. At picnics and barbecues, food is often served buffet style or in shared bowls, making it more prone to germs. Add to that double dipping, and you've swapped spit with everyone at the party.
And don't forget to store and handle food properly — especially meat — when outside. The last thing you need this Summer is a bad case of food poisoning because your potato salad sat out too long.
