7 Ways You’re Grilling All Wrong

2. You don't clean your grill

Since a grill is kept outside, you may feel you don't need to keep it clean like you would the stove in your kitchen. But foodborne germs can spread just as easily outdoors as indoors. Although the CDC doesn't have explicit guidelines for cleaning grills, Katzowitz suggests washing grates and prep surfaces with hot, soapy water before cooking. Don't forget to clean tongs, spatulas and other grilling utensils while you're at it.

3. You neglect your grill brush

A grill brush is a great tool for removing charred residue from grates, but if you use a wire brush, be aware that bristles may fall off and later get stuck in your food. After cleaning your grill with a brush, use a wet cloth or paper towel to wipe off any loose bristles. One way to avoid the risk of bristles altogether is to instead use a balled-up piece of aluminum foil to scrub the grates. If the grill is cool, grasp the foil ball with your hand and scrub; if it's hot, use a pair of tongs as a makeshift handle.

4. You don't separate raw and cooked foods

Cross contamination is the enemy, so don't use the same utensils and plates that came into contact with raw meats to serve the meal. Don't let fruits, vegetables and other foods you plan to eat uncooked come into contact with raw meats, meat juices or meat marinades. Wash your hands with soap and water before cooking and again after handling raw meats. Raw meats, including poultry and seafood, can be contaminated with salmonella, E. coli and other potentially harmful bacteria.

5. You don't refrigerate food soon enough

Raw meat, poultry and seafood needs to be kept refrigerated below 40 degrees Fahrenheit until just before you're ready to throw them on the grill. Germs can start to multiply once the internal temperature rises above 40 degrees. In general, leftovers should be refrigerated or frozen within two hours of cooking. However, if you are grilling on a hot day and it's above 90 degrees outside, food should be refrigerated or frozen within one hour of cooking.

6. You char your meat

Consuming muscle meat including beef, pork, poultry and fish that has been prepared using high heat or smoke can increase cancer risks, according to the National Cancer Institute. Potentially harmful chemicals are formed when substances inside the meat react to the high heat, flames and smoke. To reduce risks, avoid prolonged cooking at high heat, use a microwave to precook meat prior to grilling, continuously turn meat when it's being cooked over a high-heat source, and removed charred portions before consuming, advises the National Cancer Institute.

7. You undercook your meat

In general, make sure that meat, poultry and seafood are cooked to their recommended safe internal temperatures by using a food thermometer. Otherwise, the heat may not be sufficient to kill any potentially harmful germs that may be present. Since fruits and vegetables may cook more quickly than meats, if you are cooking them together on a skewer — as with kebabs — make sure the meat is fully cooked to a safe internal temperature. Cooking meats and produce on separate skewers can make it easier to prepare each to the desired level of doneness.
