As a home cook or professional chef, ensuring the meat you serve is cooked to a safe internal temperature is crucial to prevent foodborne illnesses. When it comes to pork, the recommended internal temperature has changed over the years, leaving some cooks wondering why their meat thermometer says 170°F (77°C) for pork. In this article, we’ll delve into the history of pork cooking temperatures, the science behind the current recommendations, and provide guidance on how to achieve perfectly cooked pork every time.
A Brief History of Pork Cooking Temperatures
In the past, the USDA recommended cooking pork to an internal temperature of 160°F (71°C) to ensure food safety. However, this temperature was based on outdated research and didn’t take into account the actual risk of foodborne illness from pork. In 2011, the USDA revised its guidelines, recommending a minimum internal temperature of 145°F (63°C) for whole muscle cuts of pork, followed by a 3-minute rest time. This change was made to reflect new research on the safety of pork and to provide more flexibility for cooks.
Why 170°F (77°C) for Ground Pork?
While whole muscle cuts of pork can be safely cooked to 145°F (63°C), ground pork is a different story. Ground pork, like ground beef or ground turkey, is more susceptible to contamination because the grinding process can distribute bacteria throughout the meat. As a result, the USDA recommends cooking ground pork to an internal temperature of 160°F (71°C) to ensure food safety. However, some meat thermometers may still display 170°F (77°C) as the recommended temperature for ground pork. This is likely due to the thermometer’s manufacturer following older guidelines or using a more conservative approach to ensure food safety.
The Science Behind Safe Internal Temperatures
So, why are these temperatures so important? The answer lies in the science of food safety. When meat is cooked, the heat kills bacteria and other microorganisms that can cause foodborne illness. The most common bacteria associated with pork are Trichinella, Salmonella, and E. coli. These bacteria can be present on the surface of the meat or within the meat itself.
Trichinella and the Risk of Trichinosis
Trichinella is a parasite that can be present in pork, particularly in wild game or pork from pigs that have not been raised on a commercial farm. Trichinosis, the disease caused by Trichinella, can be serious and even life-threatening. However, the risk of Trichinosis from commercially raised pork is extremely low. In fact, according to the USDA, the risk of Trichinosis from commercially raised pork is about 1 in 1 million.
Salmonella and E. coli: The Risks of Foodborne Illness
Salmonella and E. coli are two of the most common bacteria associated with foodborne illness. These bacteria can be present on the surface of the meat or within the meat itself. When meat is not cooked to a safe internal temperature, these bacteria can survive and cause illness. According to the CDC, Salmonella and E. coli are responsible for thousands of cases of foodborne illness each year.
How to Achieve Perfectly Cooked Pork
Now that we’ve covered the science behind safe internal temperatures, let’s talk about how to achieve perfectly cooked pork. Here are some tips to help you get it right:

A good meat thermometer is essential for ensuring your pork is cooked to a safe internal temperature. When choosing a meat thermometer, look for one that is accurate to ±1°F (±0.5°C) and has a fast response time. You can choose from a variety of thermometers, including digital, dial, and instant-read thermometers.
Inserting the Thermometer Correctly
To get an accurate reading, it’s essential to insert the thermometer correctly. For whole muscle cuts of pork, insert the thermometer into the thickest part of the meat, avoiding any fat or bone. For ground pork, insert the thermometer into the center of the patty or meatball.
Using the Right Cooking Method
The cooking method you use can affect the internal temperature of the pork. For example, grilling or pan-frying can result in a higher internal temperature than oven roasting. Use a cooking method that allows you to achieve a consistent internal temperature throughout the meat.
Letting it Rest
After cooking, it’s essential to let the pork rest for a few minutes before serving. This allows the juices to redistribute, making the meat more tender and flavorful. It also allows the internal temperature to rise slightly, ensuring that the meat is cooked to a safe temperature throughout.
Conclusion
In conclusion, the recommended internal temperature for pork is 145°F (63°C) for whole muscle cuts and 160°F (71°C) for ground pork. While some meat thermometers may still display 170°F (77°C) as the recommended temperature for ground pork, this is likely due to outdated guidelines or a more conservative approach to ensure food safety. By understanding the science behind safe internal temperatures and following the tips outlined in this article, you can achieve perfectly cooked pork every time.

What is the safe internal temperature for cooking pork?
The safe internal temperature for cooking pork is at least 145°F (63°C), with a three-minute rest time. This is the minimum temperature recommended by the United States Department of Agriculture (USDA) to ensure that the pork is cooked to a safe temperature to prevent foodborne illness. It’s essential to use a food thermometer to check the internal temperature of the pork, especially when cooking whole muscles like pork chops or roasts.
It’s worth noting that the internal temperature of the pork will continue to rise during the rest time, so it’s essential to remove the pork from the heat source when it reaches an internal temperature of 145°F (63°C). This allows the pork to retain its juiciness and tenderness while ensuring that it’s cooked to a safe temperature.
Why does my meat thermometer say 170°F for pork?
Some meat thermometers may recommend an internal temperature of 170°F (77°C) for pork, which is higher than the USDA’s recommended temperature of 145°F (63°C). This is because some thermometers may be calibrated to provide a more conservative estimate of the safe internal temperature for pork.
