Pork tenderloin, a lean and incredibly versatile cut of meat, is a favorite for weeknight dinners and special occasions alike. Its mild flavor and tender texture make it a blank canvas for a variety of seasonings and cooking methods. However, like all meat, ensuring it’s cooked to a safe internal temperature is paramount to prevent foodborne illness. For years, the accepted wisdom was that pork needed to reach 160°F to be safe to eat. But guidelines have changed. So, can you eat pork tenderloin at 145°F? The answer is a resounding yes, but understanding the nuances of that answer is critical for food safety and culinary success.
The USDA Guidelines and Pork Safety
The United States Department of Agriculture (USDA) significantly revised its recommendations for cooking pork in 2011. The change was driven by advancements in pork production and a better understanding of the risks associated with Trichinella spiralis, the parasite that was once the primary concern with pork consumption.
Before 2011, the USDA advised cooking pork to an internal temperature of 160°F, followed by a three-minute rest time. The new recommendation is to cook whole cuts of pork, including pork tenderloin, to a minimum internal temperature of 145°F, followed by a three-minute rest time. This shift reflects the reduced risk of Trichinella due to improved farming practices.
Why the Change in Recommendation?
The change in the USDA’s recommendation stems from several factors:
- Improved Farming Practices: Modern pig farming has greatly reduced the incidence of Trichinella. Changes in animal feed, housing, and overall sanitation have significantly minimized the risk of pigs contracting the parasite.
- Heat Penetration and Hold Time: The USDA recognizes that the temperature doesn’t have to reach a high number instantly to be considered safe to eat. The three-minute rest period after cooking allows the heat to distribute evenly throughout the meat, effectively pasteurizing it and killing any potential pathogens. This process is known as “carryover cooking.”
- Consumer Preference: Overcooking pork to 160°F often resulted in a dry, tough product. The lower temperature recommendation of 145°F allows for juicier, more flavorful pork while still ensuring safety.
The Importance of a Meat Thermometer
Relying on visual cues alone is not a reliable way to determine the internal temperature of pork tenderloin. A meat thermometer is an essential tool for safe and accurate cooking. An instant-read thermometer is ideal for quick temperature checks. Insert the thermometer into the thickest part of the tenderloin, avoiding bone or fat, to get an accurate reading.
Understanding the 145°F Requirement
Hitting the 145°F mark is crucial, but equally important is the three-minute rest period that follows. This resting time allows the heat to redistribute, ensuring that even the center of the tenderloin reaches a safe temperature.
The Three-Minute Rest: A Critical Step
The three-minute rest period is not just a suggestion; it’s a vital component of the USDA’s recommendation. During this time, the internal temperature of the pork tenderloin will continue to rise slightly, and the heat will equalize throughout the meat. This process, called carryover cooking, is essential for killing any remaining bacteria and ensuring even pasteurization.
To properly rest the pork tenderloin, remove it from the heat source and place it on a cutting board. Tent it loosely with foil to help retain heat without steaming the surface. Avoid cutting into the tenderloin before the rest period is complete, as this will allow valuable juices to escape, resulting in drier meat.
What Happens If You Don’t Rest the Pork?
Skipping the rest period compromises the safety and quality of your pork tenderloin. Without the rest, the center of the tenderloin may not reach a safe temperature, increasing the risk of foodborne illness. Additionally, cutting into the meat prematurely allows the juices to escape, resulting in a drier, less flavorful product.
Visual Cues: Not Always Reliable
While experienced cooks may develop a sense for doneness, relying solely on visual cues is not a reliable method for ensuring the safety of pork tenderloin. Factors such as the thickness of the tenderloin, the cooking method, and the oven’s accuracy can all affect the cooking time. It’s always best to use a meat thermometer to confirm the internal temperature.
Potential Risks and Considerations
While cooking pork tenderloin to 145°F with a three-minute rest is considered safe by the USDA, it’s important to be aware of potential risks and take appropriate precautions.
Foodborne Illnesses Beyond *Trichinella*
While Trichinella is no longer the primary concern with pork, other bacteria, such as Salmonella and E. coli, can still pose a risk. These bacteria can be present in raw or undercooked pork and can cause foodborne illness. Cooking pork to 145°F with a three-minute rest significantly reduces the risk of these infections.
Cross-Contamination
Preventing cross-contamination is crucial when handling raw pork. Always wash your hands thoroughly with soap and water after handling raw pork. Use separate cutting boards and utensils for raw meat and ready-to-eat foods. Clean and sanitize surfaces that have come into contact with raw pork.
Special Populations
Individuals with weakened immune systems, pregnant women, and young children are more susceptible to foodborne illnesses. These populations should exercise extra caution when consuming pork and may want to cook it to a slightly higher temperature for added safety. Consult with a healthcare professional for personalized recommendations.

Is 145°F Truly Safe for Pork Tenderloin?
Yes, 145°F is considered a safe internal temperature for cooking pork tenderloin, according to the United States Department of Agriculture (USDA). This recommendation applies to all cuts of pork, including tenderloin, chops, roasts, and ribs. However, it’s crucial to ensure that the pork reaches and holds this temperature for at least three minutes to effectively kill any harmful bacteria that may be present.
Holding the pork at 145°F for three minutes allows for the heat to thoroughly penetrate the meat, ensuring that any potentially harmful microorganisms are neutralized. Using a reliable meat thermometer is essential for verifying the internal temperature, and testing in multiple locations is advisable. Remember to let the pork rest after cooking to allow the temperatures to equalize and the juices to redistribute.
Why Was the Recommended Temperature for Pork Previously Higher?
The previously recommended internal temperature for pork was 160°F, significantly higher than the current guideline of 145°F. This higher temperature was based on concerns about the parasite Trichinella spiralis, which can cause trichinosis. However, changes in pork production practices have drastically reduced the prevalence of this parasite.
Modern farming methods, including improved feed and sanitation standards, have significantly minimized the risk of trichinosis in commercially raised pork. Consequently, the USDA updated its guidelines to reflect this reduced risk, allowing for a lower cooking temperature that results in a more tender and flavorful final product. The current recommendation balances safety with enhanced culinary quality.
What Are the Risks of Undercooking Pork Tenderloin?
Undercooking pork tenderloin can pose a risk of foodborne illness. Although modern pork production has reduced certain risks, harmful bacteria such as Salmonella, Listeria, and E. coli can still be present. These bacteria can cause symptoms ranging from mild gastrointestinal distress to more severe complications.
Consuming undercooked pork increases the likelihood of contracting a foodborne illness. Symptoms can include nausea, vomiting, diarrhea, abdominal cramps, and fever. In some cases, these illnesses can lead to hospitalization, particularly for individuals with weakened immune systems, pregnant women, young children, and older adults. Properly cooking pork to the recommended internal temperature is essential to minimize these risks.
How Can I Accurately Check the Internal Temperature of Pork Tenderloin?
Using a reliable meat thermometer is the best way to accurately check the internal temperature of pork tenderloin. Insert the thermometer into the thickest part of the tenderloin, avoiding bone or areas with excessive fat. Ensure the thermometer probe is positioned in the center of the meat for the most accurate reading.
Digital thermometers provide a rapid and precise temperature reading, making them a preferred choice for many cooks. Instant-read thermometers are also suitable but require inserting the probe a bit deeper and may take slightly longer to register the temperature. Regardless of the type used, verify the accuracy of your thermometer periodically with an ice water bath or boiling water test.
What Does “Carryover Cooking” Mean and How Does it Affect Pork Tenderloin?
Carryover cooking refers to the phenomenon where the internal temperature of meat continues to rise after it’s removed from the heat source. This occurs because the heat energy stored in the outer layers of the meat gradually transfers to the cooler center. Understanding carryover cooking is crucial for achieving perfectly cooked pork tenderloin.
Allowing the pork tenderloin to rest after cooking allows the carryover cooking process to complete. Typically, the internal temperature can rise by 5-10°F during this resting period. Therefore, it’s advisable to remove the pork from the oven or grill when it’s a few degrees below the target temperature of 145°F, then let it rest, covered loosely with foil, to reach the final temperature. This technique helps prevent overcooking and ensures a juicy, tender result.
What is the Best Way to Store Leftover Cooked Pork Tenderloin?
Proper storage of leftover cooked pork tenderloin is essential to prevent bacterial growth and ensure food safety. Once the pork has cooled slightly, wrap it tightly in airtight plastic wrap or place it in a sealed container. Refrigerate the cooked pork tenderloin promptly, ideally within two hours of cooking.
Leftover cooked pork tenderloin should be consumed within 3-4 days when stored properly in the refrigerator. Reheat thoroughly to an internal temperature of 165°F before serving to kill any bacteria that may have grown during storage. Avoid leaving cooked pork at room temperature for extended periods, as this promotes rapid bacterial growth.
Does Marinade Affect the Safe Cooking Temperature of Pork Tenderloin?
The use of a marinade does not change the recommended safe internal cooking temperature for pork tenderloin. Regardless of whether the pork has been marinated or not, it’s crucial to cook it to an internal temperature of 145°F and hold it at that temperature for at least three minutes to ensure food safety.
Marinades can enhance the flavor and tenderness of pork tenderloin, but they do not eliminate the need for proper cooking. Always discard any leftover marinade that has come into contact with raw pork. Never use it as a sauce without boiling it first to kill any potentially harmful bacteria. Always rely on a meat thermometer to verify the internal temperature, regardless of marinade use.
