Summertime is Grill Time

There's something special about grilling out-of-doors, whether on the patio or in the park. It gives foods a unique flavor and creates a festive mood of summer celebration. Today, grilling means more than hamburgers and franks. Shish kebabs, turkey, fruits and a variety of vegetables all show up on the grill.

For safety and good health, make sure your recipes and grilling methods discourage the growth of microbes and the production of cancer-causing components. Use these simple guidelines for a safe outdoor meal, whether it's marinated shish kebabs, barbecued chicken or your favorite grilled franks.

  • Select meats that are low in fat. Trim off excess fat before cooking. The more fat, the greater the production of carcinogens during charcoal broiling.
  • Keep meat, poultry, salads and other perishables refrigerated or in an insulated cooler with an ice source until ready to grill.
  • Marinate meats in a glass dish in the refrigerator, not on the counter. Once the meat has been put on the grill, throw out any left over marinade. It will contain any bacteria found on the surface of the raw meat. If you want to use some of the marinade as a sauce or dip, set it aside before marinating the meat.
  • Precooking can save time at the grill site and reduce charring. However, for safety's sake, make sure foods go directly from the microwave or oven to the grill. Foods also may be completely cooked, then quickly cooled for later reheating on the grill.
  • Take out only the amount of food that you will cook and eat. Do not let foods sit in warm temperatures for more than two hours. When it's more than 85 degrees, the time limit is an hour or less.
  • For safety and quality, have the coals ready before putting food on the grill. Coals should have a light coating of ash for optimal heat. Avoid extremely hot temperatures, as they promote the formation of carcinogenic compounds on the surface of the meat.
  • Use a wire brush to scrape off any charred pieces left on the grill before adding the meat or vegetable to be cooked. The charred pieces can harbor both bacteria and potential carcinogens.
  • Use a meat thermometer or T-stick to make sure the meat is cooked to a safe temperature. Hamburgers and other ground meats need to be cooked to an internal temperature of 160 degrees.
  • Discourage flare-ups. Burning juice or fat can produce harmful smoke. If smoke from dripping fat is too heavy, move the food to another section of the grill, rotate the grill, or reduce the heat. If you have a gas or electric grill, lower the temperature setting. For conventional grills, use a squirt bottle of water to dampen the coals.
  • When possible, use a drip pan to catch dripping fat. Metal drip pans are available where outdoor cooking equipment is sold, or make your own from heavy duty aluminum foil. Do not let the drip pan rest on burning coals. With gas or electric grills, follow the manufacturer's instructions on the use and placement of drip pans.
  • Serve food from the grill on a clean platter, not one that has raw, possibly contaminated juices on it.
  • After grilling, serve immediately to keep hot foods hot.
  • Clean the grill after each use.
  • Refrigerate any leftovers promptly. If this is not possible and the perishable foods will sit at warm temperatures longer than two hours, the safest motto is, "When in doubt, throw it out."
