To make sure foods get hot enough, check the internal temperature by inserting a food thermometer in the thickest part. Cook fish until it flakes with a fork. Simmer shrimp for three to five minutes or until the flesh turns pinkish and opaque. Cook oysters until they're plump, for about five minutes. Don't eat raw oysters.
Commercial versions are okay, since manufacturers use heat-treated eggs.
Use hard-boiled eggs within two to three days of cooking. Grilling precautions Marinate meats in the refrigerator. If you plan to use some of the marinade for a dip or basting sauce, make sure it has been boiled for at least 1 minute. Keep vegetables or fruits intended for grilling separate from raw meats so no one will unwittingly munch on an uncooked, possibly contaminated piece of produce. If you partially cook meat in advance to reduce grilling time, put it on the grill immediately afterward.
