Why You Must Cook Ground Beef to 155°F (and How to Do It Right)

Ground beef is a staple ingredient in many delicious dishes like burgers, tacos, chili, and meatloaf But did you know that cooking it properly to an internal temperature of 155°F is crucial for food safety?

I’m going to explain exactly why you need to cook ground beef to 155°F, the risks of undercooked beef, how to check the temperature, and tips for nailing this temperature when cooking. Let’s dive in!

Why 155°F for Ground Beef?

The short answer is that it kills any harmful bacteria like E. coli or salmonella that could be present in the raw meat. Here’s a more detailed explanation:

  • Ground beef is more susceptible to bacteria contamination because the grinding process mixes any pathogens present on the meat surfaces throughout the batch

  • E. coli is the main bacteria of concern with ground beef. Consuming undercooked beef with E coli can cause severe food poisoning with symptoms like diarrhea, vomiting, and stomach cramps

  • Heating ground beef to the FDA-recommended internal temperature of 155°F is proven to destroy E. coli and other dangerous organisms.

  • For public health simplicity, the USDA actually recommends cooking ground beef to 160°F since it’s easier to remember one temperature rule rather than 155°F held for 15 seconds.

Dangers of Undercooked Ground Beef

Eating rare or medium-rare ground beef is simply not worth the risk. Here are some key dangers to understand:

  • E. coli infection: Undercooked ground beef is the #1 cause of E. coli poisoning. Symptoms of infection appear 2-8 days after eating contaminated meat.

  • Mechanical tenderizing: This process can drive E. coli deeper into the meat where it may survive lower cooking temperatures.

  • No visual cues: Unlike steaks, the color and texture of ground beef does not indicate safe doneness. Use a thermometer instead!

  • Cross-contamination: Bacteria from raw meat can spread to surfaces, utensils, and other foods if proper precautions aren’t taken.

The bottom line is you should always cook ground beef to the recommended safe minimum internal temperature. Food safety is nothing to gamble with.

How to Check the Temperature of Ground Beef

Using an instant-read digital thermometer is by far the most reliable way to check ground beef temperature.

Here are some tips for using a thermometer correctly:

  • Insert the probe into the thickest part of the patty and make sure it’s not touching any pan or bone.

  • Check temperature towards the end of cooking time but before expected doneness.

  • Ground beef continues cooking after removal from heat. For medium doneness, remove from heat around 150°F.

  • Clean the thermometer probe carefully between tests to avoid cross-contamination.

If you don’t have a thermometer, you can check firmness, but this is much less accurate. If the meat is soft and squishy, it’s rare. If firmer, it’s more well-done. Stick to using a good meat thermometer whenever possible.

Tips for Cooking Ground Beef to 155°F

Achieving the food-safe 155°F ground beef temperature is easy when you follow these handy tips:

  • Use leaner beef: Fattier ground beef requires more cooking time to reach 155°F and risks overcooking. Go for 85/15 or 90/10 blends.

  • Sauté before simmering: Browning ground beef in a skillet before slow braising helps seal in moisture and flavor.

  • Season well: Spices and herbs amp up flavor without extra fat or calories. Garlic, onions, chili powder, oregano, and paprika all taste great with beef.

  • Avoid overcrowding: Too much beef in the pan steams instead of browns. Cook in batches for the best texture.

  • Let it rest: After cooking, let ground beef rest for 5-10 minutes to allow heat to distribute evenly and complete cooking.

  • Use a meat mallet: For thicker burgers or meatloaf, flatten beef with a mallet so the inside cooks through.

With the right techniques and a good thermometer, cooking ground beef properly to 155°F is easy and ensures you serve tasty, safe meals. Give it a try on your next taco night!

Frequently Asked Questions

Why is the temperature different for restaurants vs home cooks?

The FDA Food Code states restaurants should cook ground beef to 155°F held for 15 seconds. For simplicity, the USDA recommends a single 160°F standard for consumers instead of both time and temperature.

Is it OK to eat ground beef medium or rare?

No, absolutely not! Ground beef should always be cooked to at least 155°F internally to kill bacteria that could cause life-threatening illness if ingested. Never eat undercooked ground beef.

What is the safest way to thaw ground beef?

Thaw frozen ground beef gradually in the fridge on the bottom shelf to prevent raw meat juices from dripping onto other foods. Avoid thawing at room temperature.

Can you cook frozen ground beef without thawing?

You can cook frozen beef directly from frozen but it will take 50% longer. Make sure to cook to the proper internal temperature.

What color should cooked ground beef be?

When beef reaches 155°F, it should be light brown throughout with no traces of pink. However, color is not the best doneness indicator. Always use a meat thermometer.

Can you eat ground beef that smells bad?

No! Rancid, sour, or unpleasant odors likely mean spoilage and bacteria growth. Discard beef with an off-putting smell and do not consume it.
