In anticipation of the beginning of football and tailgating season, I have put together some of the most frequently asked questions that USDA's Meat and Poultry Hotline receives about hamburgers and food safety. Whether you’re grilling burgers at home or outside the stadium, here’s what you need to know:
Do you have guidelines for buying ground beef or hamburgers? What's the best way to handle them?
- Choose a package that is not torn and feels cold. If possible, put it in a plastic bag so leaking juices won't drip on other foods.
- Make ground beef one of the last items to go into your shopping cart. Be sure to separate raw meat from ready-cooked items in your cart.
- Have the cashier bag raw meat separately from other items and plan to drive directly home. You may want to take a cooler with ice for perishables.
How should I store ground beef at home?
Refrigerate or freeze ground beef as soon as possible after purchasing. This preserves freshness and slows growth of bacteria. It can be refrigerated or frozen in its original packaging if the meat will be used soon.
- If refrigerated, keep at 40 °F or below and use within 1 or 2 days.
- For longer freezer storage, wrap in heavy duty plastic wrap, aluminum foil, freezer paper, or plastic bags made for freezing. Ground beef is safe indefinitely if kept frozen at 0 °F, but will lose quality over time. It is best if used within 4 months.
- Never leave ground beef or any perishable food out at room temperature for more than 2 hours (1 hour at 90 °F and above).
Is It Done Yet? How can I tell when my burgers are safely cooked?
Hamburgers should be cooked to a safe minimum internal temperature to destroy harmful bacteria that may be present. Use a food thermometer to be sure they have reached a safe minimum internal temperature of 160 °F. If you’re cooking turkey burgers, they should be cooked to 165 °F.
- NEVER partially grill meat or poultry and finish cooking later.
- Keep Hot Food Hot! After cooking meat and poultry on the grill, keep it hot until served — at 140 °F or warmer. Keep cooked meats hot by setting them to the side of the grill rack, not directly over the coals where they could overcook. If you’re at home, the cooked meat can be kept hot in an oven set at approximately 200 °F, in a chafing dish or slow cooker, or on a warming tray.
I worry about my father-in-law forgetting to take a clean plate to the grill for cooked burger. Is it safe to use the same plate for raw and cooked burgers?
No. To prevent foodborne illness, don't use the same platter and utensils for raw and cooked hamburgers. Harmful bacteria present in raw meat and their juices can contaminate safely cooked food. You can either use a clean plate for the cooked burgers or wash the one that held the raw ones.
Can I refrigerate or freeze leftover cooked hamburgers?
Yes, if ground beef is refrigerated promptly after cooking (within 2 hours; 1 hour if the temperature is above 90 °F), it can be safely refrigerated for about 3 or 4 days. If frozen, it should keep its quality for about 4 months.

I will bake 60 hamburgers in oven this Friday. Put in fridge overnight for Saturday bbq. Can I store hamburgers with beef broth in fridge until party. Thank you.
@Herbert - You may safely do this, however there are a few things you need to do first:
- Cook the burgers thoroughly, making sure they reach 160°F as measured by a food thermometer.
- Since you won’t be using these right away & you’re making a large quantity divide them into shallow containers & refrigerate promptly. They need to cool rapidly. And,
- If planning to reheat, ensure they reach 165°F before serving as measured by a food thermometer.

I left out turkey burgers overnight by accident. I got up early this morning and put it in the fridge. Is it safe to eat?
@rhemajc101 - we're sorry to tell you that it is not safe to use this product. Just two hours at room temperature is enough time for food poisoning bacteria to reach dangerous levels. Plus, there are some bacteria that, if allowed to multiply, produce toxins that cannot be killed by cooking.
Since your food was out overnight, you should not use it.
Is it safe to cook burgers in the plastic it comes with in a oven. When i say safe i mean for people to eat it like that.
@Neal Lucas - thank you for your comment. We do not recommend to cook burgers in the packaging it comes in. Although this package is food safe, most of these plastic packages are not designed to sustain high temperature like oven temperatures. It’s best to remove them first. We hope this helps!
I understand beef is safe to hold at 200°F but I would like to know the maximum number of hours it should be held. Time matters as well as temperature.
@Jeni - thank you for your comment. As long as the product is held at a safe temperature, it is safe. There is no maximum number of hours. The longer it is held at this temperature however, it’ll begin to dry out and lose quality and flavor.
