Yes, cooked ribs can sometimes be pink inside, even when fully cooked to a safe temperature. The pink color doesn't always indicate undercooked meat.
Understanding the Pink Color in Cooked Ribs
The pink hue in cooked ribs is often due to the presence of myoglobin, a protein that carries oxygen in muscle tissue. The level of myoglobin varies depending on the animal's age, diet, and the cut of meat. Slow cooking methods, especially those involving low temperatures over extended periods, can result in a pink color even when the internal temperature reaches safe levels. This is especially true for ribs, which benefit from longer cooking times to achieve tenderness.
-
Safe Internal Temperature: While a pink color can be present, it's crucial to ensure the ribs reach a safe internal temperature of 145°F (63°C) to 160°F (71°C) to eliminate any potential foodborne illness. Using a reliable meat thermometer is essential for accurate temperature verification.
-
Other Indicators of Doneness: Along with temperature, other indicators of doneness include tender meat that easily pulls away from the bone, and clear (not pink) juices. However, these methods alone are not definitive, so a thermometer remains crucial.
-
The Effect of Smoking: Smoking can further affect the color of the meat. A "smoke ring" often appears pinkish, even in well-cooked meat.

Example: A reference states that when pork is cooked to 145°F to 150°F, it is considered medium-rare and there will be some pink. [Source: Reddit - r/foodsafety]
When Pinkness Might Indicate Undercooked Ribs
While often harmless, a persistent, deep pink color throughout the meat, especially when accompanied by red juices, might indicate undercooked ribs. In such cases, further cooking is necessary to ensure food safety.
Conclusion
The presence of some pink in cooked ribs doesn't automatically mean the meat is undercooked. However, always prioritize checking the internal temperature with a meat thermometer to ensure it reaches a safe level. A pale pink or slightly pink hue in areas with clear juices, after reaching the proper temperature, is generally acceptable.
