What Is the Minimum Temperature for Ground Beef
The Internal Temperature of a Hamburger When Washed
The USDA'south recommended safe minimum internal temperature of a hamburger when done is 160 degrees Fahrenheit. This is the recommendation for consumers cooking burgers at home.
The 2017 FDA Food Code (it's updated every iv years) states that a hamburger'south safe minimum internal temperature when done is 158 degrees Fahrenheit.
The FDA'south food code besides updated in its recommendations a minimum internal temperature for footing beefiness of 155 degrees with a minimum 17-2nd holding time above that temperature.
So, why the discrepancies, and what'southward the temperature for a cooked hamburger then? I will discuss the discrepancies in a bit, but let's examine how to cook a prophylactic and delicious hamburger beginning.
In that location are cooking and preparation methods that will permit you to melt and serve your hamburgers safely below160 degrees Fahrenheit, which is unremarkably considered the well done burger temp.
One cooking method that volition allow you lot to safely serve a burger with a burger internal temp even at 140 degrees Fahrenheit is the melt and hold technique which will eliminate harmful bacteria through the process known as meat pasteurization.
I volition also examine the training method of grinding your ain meat that some culinary enthusiasts will proclaim makes consuming a medium-rare burger safe to consume.
Then I'll evidence you the necessary steps that they skip before grinding that you need to accept to limit the bacteria in a medium-rare burger.
In this article, I will detail these two methods and show you how to cook and serve a prophylactic and delicious burger at an internal temp below 160 degrees Fahrenheit.
First, let'due south look at the FDA's holding time recommendation and how that tin help united states cook a burger that's safer and juicer at the same time.

Time and Temperature: Pasteurization in Footing Beef Patties
The holding time stipulation of 17-seconds mentioned in the FDA's recommended ground beef internal temp minimum of 155 degrees Fahrenheit is the primal to cooking your burgers beneath 160 degrees Fahrenheit.
Destroying harmful pathogens in meat is non only achieved by college temperatures but by both temperature and time working together.
This process is known as meat pasteurization and it will permit you to cook your hamburger below 160 degrees Fahrenheit. Do you need special equipment?
Cooking a hamburger in a skillet, registering nearly 137 degrees Fahrenheit, assuasive for carryover cooking, information technology is set for the oven to hold its temperature for 12 minutes.

Nope. Just melt your hamburger to 1 of the internal temperatures listed in the FDA's Time and Temperature nautical chart below and and then concur it at or in a higher place that temperature for a specified amount of time and y'all will kill the same amount of pathogens as if you cooked it to 160 degrees Fahrenheit.

As you can see, due to practicality and time constraints, using this pasteurization technique for cooking hamburgers but makes sense higher up 140 degrees Fahrenheit. How practice you do this? Read on.

Hamburger Internal Temp Recommendations
Why is 160 degrees Fahrenheit considered the safe hamburger internal temperature?
A burger's internal temp of 160 degrees Fahrenheit is the temperature at which harmful bacteria such as East. coli and Salmonella are eradicated instantly from ground beef.
This conservative recommendation for the home cook is intended to safeguard against a "worst-case" scenario.
The FDA food code chart mentioned previously is based on a six.5 log-10 reduction (or vi.5D reduction) in harmful pathogens such as E. coli and Salmonella.
What does that mean exactly?
In the context of killing leaner in food, a log reduction is a mensurate of how thoroughly the cooking process reduces the concentration of harmful pathogens.
The log part of it refers to alogarithm.In this case, it is the ratio of levels of leaner before and subsequently the cooking process. An increase of 1 corresponds to a reduction in bacteria by a factor of 10.
A log reduction of 0 refers to no reduction in bacteria and a ane-log reduction corresponds to a 90% reduction.
Each log reduction increases the number of bacteria killed by a factor of 10:
- 1 log reduction = 90% reduction in Salmonella
- 2 log reduction = 99% reduction
- three log reduction = 99.9% reduction
- iv log reduction = 99.99% reduction
- 5 log reduction = 99.999% reduction
- half-dozen log reduction = 99.9999% reduction
As you can encounter, a vi.5 log-10 reduction equates to an over 99.9999% reduction in bacteria. If y'all're interested in learning more than well-nigh the thermal devastation of microorganisms, here'southward another link to the FDA's literature.
Why Is the Minimum Prophylactic Temperature of a Hamburger Higher Than a Steak's?
Why is the minimum safe temperature of a hamburger higher than whole pieces of beefiness, like a flank steak for case?
Information technology is because harmful bacteria tin can exist on the surface of a piece of beefiness before it is footing.
Whole, intact cuts of beef are sterile on the inside with most bacteria plant on the surface of the meat, according to the North American Meat Establish.
When this beefiness is footing, this surface bacteria is then introduced and integrated all over the basis beef mixture.
So instead of having to worry well-nigh just killing the surface bacteria equally y'all would cooking a steak, y'all now have to ensure that every part of your hamburger is gratis from harmful pathogens.
When you cook a steak on a hot surface the surface bacteria is immediately killed.
Is Ground Beefiness Done at 158 Degrees or 160 Degrees Fahrenheit?
So, why does there seem to be a discrepancy between some of the minimum safe temperatures recommended past the USDA, FDA, and the CDC?
Good question.
Here's a direct quote from the CDC (Centers for Disease Control and Prevention) pertaining to the guidelines for cooking basis beef:
The FDA Food Code says that restaurants should cook ground beef to 155°F for 17 seconds. But CDC and USDA say that consumers should melt ground beef to 160°F. The guidance for consumers is unlike because it is simpler to meet one standard (temperature) than two (temperature and fourth dimension). Cooking ground beefiness to 160°F kills East. coli germs rapidly.
How well-nigh some intra-agency cooperation?
Information technology appears that the difference in temperatures stems from the government agencies not wanting to confuse the consumers at home with too much information.
To simplify it, they've kept the recommendation for basis beef at 160 degrees Fahrenheit.
Even the FDA states 2 separate temperatures, every bit evidenced by this FDA temperature chart recommending 160 degrees Fahrenheit as basis beef's safety minimum internal temperature.
This is different from the 158 degrees Fahrenheit recommendation that they published in the 2017 food lawmaking the very same year as that temperature chart.
For our purposes in this commodity, this discrepancy doesn't come into play equally we are going to cook and hold our hamburger to a lower temperature anyway.
Cooking a Hamburger to a Serving Temperature Below 160 Degrees Fahrenheit
How do you use the melt-and-hold method to cook safe and juicy hamburgers below the recommended minimum safe temperatures?
I'll show y'all right at present.
We are going to melt our hamburgers to an internal temperature of 140 degrees and and then hold them higher up that temperature for 12 minutes.

Keep in mind I'chiliad using a 5-ounce hamburger patty in this case. The cooking time volition vary for y'all depending on the size of your meat.
First, preheat your oven to 250 degrees Fahrenheit. If you're using a grill, don't worry, you lot can move your burgers off to the side of the oestrus.
Form your hamburger patties to your desired size. Retrieve to make a 1/4 inch dimple in the eye of your hamburger patty. The exterior of a burger cooks faster than the middle.
Meat shrinks equally it cooks, the shrinking meat on the exterior and so pushes the uncooked meat in the middle up and out.
That's why you get softball-shaped burgers if you don't dimple them first.
Side by side, heat a skillet or your grill to medium-high estrus for around v to x minutes. This will by and large measure out a surface temperature between 450 and 500 degrees Fahrenheit in your skillet or on your grill grates.
Grill your burger dimple side up for iii minutes, so flip.

Grill the other side for another three minutes.
Hamburger cooking in a skillet over medium-high heat at the six-minute mark, measuring an internal temperature of 95 degrees Fahrenheit.
At the six-minute marking, your hamburger's internal temperature volition measure out around 95 to 100-degrees Fahrenheit. To ensure that you don't overcook one side yous will need to flip information technology over every minute until you get shut to 140 degrees Fahrenheit.
Hamburger cooking in a skillet over medium-high heat at the eight-minute mark, measuring an internal temperature of 128 degrees Fahrenheit.
Once your hamburger reaches 140 degrees Fahrenheit internally, transfer information technology, still in the skillet, to the preheated oven.
Or if you're grilling, only wrap your burgers in foil and move them to the side of the grill away from the oestrus.
Turn your oven off. Set a timer for 12 minutes. Your burger will invariably get up in temperature due to carryover cooking.

Grinding Your Own Meat for Hamburgers, Is it Safer?
Some people like their hamburgers cooked to less than 140 degrees Fahrenheit. It is at this point that some people suggest grinding your own meat at dwelling house.
What does grinding your own meat take to do with the minimum safe temperature for hamburgers?
The safety premise behind grinding your ain meat at home presupposes that the piece of meat you lot're grinding is gratuitous from bacteria on its surface.
You would and then be able to grind this piece of meat and have no surface bacteria in your grind mixture.
Then you lot could melt your hamburger to temperatures usually reserved for whole cuts of beefiness, similar a medium-rare steak for instance, generally in the 125 to 130 degree Fahrenheit range.
At that place are a few things that are logically flawed with this arroyo.
In fact, the USDA cautions against grinding beef at home.
On the USDA's website, in the section nearly ground beef and nutrient safety they land:
In a USDA-inspected plant, trimmed beefiness destined for grinding is tested for the presence of E. coli. Even so, primal cuts, such every bit steaks and roasts, are usually non tested. When stores or consumers grind these primal cuts, it's possible that pathogens may be nowadays on the raw beef, and neither you nor meat market employees can see, aroma, or taste dangerous bacteria.
In that location is no way for yous to know if the chuck roast that you're grinding into hamburger is complimentary from pathogens on the outer surface.
That is unless you decide to kill any surface bacteria by giving your meat a douse in humid water outset before grinding, I'll become into more detail on this in a minute.

Bold the cold-chain is preserved from the processing plant to shop shelf, this USDA-inspected ground beef volition be safer than grinding your ain beef at dwelling house.
Grinding Your Ain Meat for a Hamburger
The process of grinding your own meat at home is touted every bit a safer way to consume undercooked ground beef at dwelling house.
This premise is based on the balls that the whole piece of beef yous're grinding is free from any bacteria on its outside surface.
At that place is no way to know this, so you lot must take another step to ensure that the outside of your whole slice of beefiness is free from pathogens.
1 style to accomplish this is to immerse your meat in boiling water or to sear the outside briefly.
I decided to immerse pieces of chuck roast in humid h2o for 10 seconds. After their dip in the boiling water, I immediately dropped them in an ice-h2o bath to end the outside from overcooking.

The x-second boiling water plunge resulted in the pieces of chuck roast that had a surface temperature of 155 to 156 degrees Fahrenheit when measured with the Thermoworks IRK-2 Infrared Thermometer.
Considering that the surface of the chuck roast pieces were notwithstanding measuring this temperature out of the water a 2d or two afterward, I don't experience that it is a achieve to assume the surface reached a higher temperature while in the water bathroom.
Am I willing to state that those pieces of chuck roast are totally bacteria-free? No, that would exist irresponsible.
Nonetheless, I am very confident that those pieces of chuck roast destined for the meat grinder take inherently less risk of leaner because of the boosted boiling water plunge.
This pre-treatment of meat pieces in humid water is an abbreviated version of what Harold McGee recommends in his seminal work, On Nutrient and Cooking: The Science and Lore of the Kitchen.
McGee is renowned the world over for his contributions to food science.
Formed hamburger patties from the ground chuck roast pieces that were immersed in boiling water for 10 seconds.
Hamburger cooked to an internal temperature of 125 degrees Fahrenheit.
Tin Freezing Impale Bacteria in Ground Beef?
No. The uncomplicated deed of freezing your ground beef does not kill the possible bacteria that could be present. Freezing food to 0° Celsius or 32° Fahrenheit will just inactivate whatsoever bacteria that is nowadays in your food.
Once your frozen nutrient is thawed, the leaner become active once again and can multiply rapidly in the Danger Zone between 40 degrees and 140 degrees Fahrenheit.
Final Thoughts
Cooking a hamburger that is both flavorful and safe involves a certain level of risk mitigation.
My main goal in this article is to equip you with all of the necessary literature and information on limiting the gamble potential associated with eating hamburgers below 160 degrees Fahrenheit.
Armed with that information, you tin and so make an informed conclusion on how to go about cooking and serving burgers that are safe for your family, no affair the hamburger done temp you prefer.
How you like your hamburger prepared is a personal preference. Some people like their hamburgers well-done, some like them medium-rare.
However, due to the bacterial issues associated with ground meat, preparing and serving a safe burger at temperatures generally reserved for whole pieces of meat such equally steak is a challenging task for fifty-fifty the near experienced cook.
By employing cooking techniques such as the cook-and-concord method, you tin serve a hamburger that is not only flavorful and juicy, but safe besides.
By bringing the internal temperature of a hamburger to 140 degrees Fahrenheit and holding it above that temperature for 12 minutes, yous will impale the aforementioned corporeality of pathogens as you lot would at 160 degrees Fahrenheit.
People that desire an even lower internal temperature for their hamburger volition need to look at grinding their own meat after it's been sterilized on the outside past either searing or humid-h2o submersion.
Without that necessary step, yous are putting a lot of organized religion in the concatenation of events that led that slice of beefiness to your kitchen.
Whichever technique you cull to fix your burgers, always keep safety in mind. Oh, and a dependable meat thermometer.
Relish those burgers!
