Pork Perplexity: Unraveling the Mystery Behind Your Meat Thermometer’s Reading of 170

If you’re an avid meat enthusiast, you’ve likely encountered the perplexing question, “Why does my meat thermometer say 170 for pork?” This discrepancy between the recommended cooking temperature of 145°F (63°C) and the thermometer reading of 170°F (77°C) can leave you scratching your head. This guide will delve into the reasons behind this discrepancy and provide you with the necessary knowledge to cook pork safely and perfectly.

Understanding the USDA Guidelines

The United States Department of Agriculture (USDA) recommends cooking whole pork cuts, such as pork chops, pork loins, and roasts, to an internal temperature of 145°F (63°C). This temperature effectively kills harmful bacteria, including Trichinella spiralis, which can cause trichinosis.

Internal Temperature vs. Carryover Cooking

When you insert a meat thermometer into pork, it measures the internal temperature. However, once you remove the pork from the heat, the internal temperature continues to rise due to carryover cooking. This is because the heat trapped within the meat continues to cook it even after it’s been taken off the heat source.

Why Does the Thermometer Say 170°F?

The 170°F reading on your meat thermometer accounts for the carryover cooking that occurs after the pork is removed from the heat. By the time the thermometer reaches 170°F, the internal temperature of the pork has reached the recommended safe temperature of 145°F.

Factors Affecting Carryover Cooking

The amount of carryover cooking that occurs depends on several factors:

• Size and shape of the meat: Larger and thicker cuts of meat will experience more carryover cooking than smaller, thinner cuts.
• Temperature of the heat source: Higher cooking temperatures will result in more carryover cooking.
• Resting time: Allowing the meat to rest for a period of time after cooking allows the internal temperature to distribute evenly, resulting in more accurate temperature readings.

How to Cook Pork Safely

To ensure your pork is cooked safely and to the correct temperature, follow these steps:

• Use a reliable meat thermometer: Calibrate your meat thermometer regularly to ensure accurate readings.
• Insert the thermometer into the thickest part of the meat: Avoid touching any bones or fat.
• Cook to the recommended internal temperature: For whole pork cuts, aim for an internal temperature of 145°F (63°C).
• Let the meat rest: Allow the pork to rest for 10-15 minutes before carving and serving.

When to Cook Pork to 170°F

While the USDA recommends cooking whole pork cuts to 145°F, there are certain situations where cooking to 170°F may be advisable:

• Ground pork: Ground pork should be cooked to an internal temperature of 160°F (71°C) to ensure the safety of all parts of the meat.
• Pork used in dishes that will be reheated: If you plan to reheat pork in a dish, cooking it to 170°F initially will ensure it reaches a safe temperature when reheated.

Summary: Cooking Pork with Confidence

Understanding the reasons behind the discrepancy between the recommended cooking temperature and the thermometer reading of 170°F for pork will empower you to cook pork safely and perfectly every time. By following the guidelines outlined in this guide, you can enjoy delicious and wholesome pork meals without any concerns.

Frequently Asked Questions

Q: Why does my meat thermometer fluctuate while cooking pork?
A: Fluctuations in the thermometer reading are normal due to temperature changes within the meat and the surrounding environment.

Q: Can I eat pork if the thermometer reads 165°F (74°C)?
A: Yes, it’s generally safe to eat pork that has reached an internal temperature of 165°F (74°C) for at least 3 minutes. However, it’s always best to aim for the recommended temperature of 145°F (63°C) to ensure maximum safety.

Q: How long should I rest pork before carving?
A: Resting pork for 10-15 minutes allows the juices to redistribute, resulting in a more tender and flavorful meat.
