Can I place meat and poultry together on the grill for cooking?

Meat and poultry can be placed  together on the grill for cooking. It's important to use a food thermometer to be sure all of the food has reached a high enough temperature to destroy foodborne bacteria. All poultry should reach a safe minimum internal temperature of 165 °F (73.9 °C) as measured with a food thermometer.  For whole poultry, check the internal temperature in the innermost part of the thigh and wing and the thickest part of the breast. Beef, veal, and lamb steaks, roasts and chops can be cooked to 145 °F (62.8°C) with a 3 minute rest time. Hamburgers made of ground beef should reach 160 °F (71.1°F).

NEVER partially grill meat or poultry and finish cooking later. You can read more about grilling food safely at Barbecue Food Safety
