WASHINGTON, D.C.(KMIT)- With the 4th of July typically comes a lot of food, and the USDA reminds people to be safe when preparing food this weekend. USDA Food Safety Expert Archie Magoulas says to always practice cleanliness and urges backyard chefs to use a food thermometer, not the eyes, when deciding whether burgers, chicken, or fish are ready.

Magoulas also says to avoid cross-contamination of cooked and raw foods.

He says leftovers, if stored properly, can be eaten for several days.

If you have questions, USDA reps are available to answer them from 9 am until 5 pm today at ask.usda.gov.
