Pork tenderloin is a lean, flavorful cut of meat that is perfect for a quick and easy weeknight meal. But like all meat, pork tenderloin can go bad if it is not stored properly. If you are unsure whether or not your pork tenderloin is still good, there are a few things you can check for to help you make a decision.
The first thing you should check is the color of the meat. Fresh pork tenderloin should be a light pink color. If the meat is brown or gray, it is likely that it has gone bad and should be discarded. You should also check the smell of the meat. Fresh pork tenderloin should have a mild, slightly sweet smell. If the meat smells sour or off, it is likely that it has gone bad and should be discarded.
Finally, you should check the texture of the meat. Fresh pork tenderloin should be firm to the touch. If the meat is slimy or mushy, it is likely that it has gone bad and should be discarded. If you are unsure whether or not your pork tenderloin is still good, it is always best to err on the side of caution and discard it.
Checking for White Mold Growth
White mold growth is a common sign that pork tenderloin has gone bad. Here are seven steps to check for white mold growth:
- Inspect the surface of the tenderloin for any white, fuzzy patches. These patches may be small or large, and they may be accompanied by a sour smell.
- Check the underside of the tenderloin, as mold can often grow in areas that are not exposed to air.
- Cut into the tenderloin and examine the interior. If you see any white or discolored streaks or spots, this could be a sign of mold growth.
- Smell the tenderloin. If it has a sour, musty, or ammonia-like odor, this is a strong indication that it has gone bad.
- Check the packaging of the tenderloin. If the packaging is damaged or has any signs of leakage, this could allow bacteria and mold to enter the meat.
- Consider the storage conditions. If the tenderloin has been stored at room temperature for more than two hours, it is more likely to develop mold.
- Refer to the USDA’s safe food storage guidelines. They recommend discarding pork tenderloin after three to four days in the refrigerator or one year in the freezer.
| Sign | Indication |
|---|---|
| White, fuzzy patches on the surface | Mold growth |
| Sour, musty, or ammonia-like odor | Spoilage |
| White or discolored streaks or spots inside the meat | Mold growth |
Assessing Changes in Fat Coloration
Inspect the fat surrounding the tenderloin. Fresh pork tenderloin typically has white or light pink fat. As the meat ages, the fat may begin to yellow or gray, indicating the onset of spoilage.
- White or light pink fat: Fresh, safe to consume
- Yellowish fat: May still be safe, but should be used soon
- Gray fat: Spoiled, discard immediately
Additional Considerations:
- The rate of fat discoloration can vary depending on storage conditions and the initial quality of the meat.
- If the fat has a slimy or sticky texture, it is a sign of bacterial growth and should be discarded.
- Discoloration may be more pronounced on the surface of the meat and less evident towards the center.
- Always cook pork tenderloin to an internal temperature of 145°F (63°C) as measured by a meat thermometer, regardless of the appearance of the fat.
