Picnicking can be a lot of fun, but nothing can ruin your outdoor meal faster than a case of food poisoning. To reduce your risk, the United States Department of Health & Human Services suggests: packing any meat, seafood, poultry, sandwiches, summer salads, fruit, vegetables, and dairy products in a cold cooler; fill the cooler with ice to help it stay colder longer; and store it in a shady spot. —Department of Health & Human Services, June 2017
