The internal temperature of pork ribs is an important factor in determining when they are done. However, taking an accurate internal temperature in pork ribs is a difficult proposition due to thin layers of meat and interspersed bones, so it is recommended to use a thermometer to get the most accurate temperature reading. The best internal temperature for pork ribs is approximately 200 degrees F. Here are the recommended internal temperatures for different types of pork ribs:

• Spare Ribs and St. Louis Style Ribs: 200-202 degrees F
• Baby Back Ribs: 198-200 degrees F
• Country Style Ribs: 202-205 degrees F

It is important to note that the temperature readings taken directly in rib meat can vary pretty widely from one end of your rack to the other, and change based on proximity to a rib bone. Therefore, it is recommended to use a thermometer to check the internal temperature of the thickest part of the meat, away from the bone, to ensure that the ribs are cooked to the desired temperature. Additionally, ribs should be cooked past the temperature of doneness to allow the fat and collagen throughout the meat to break down and flavor the ribs, which contributes to the overall taste and texture of the ribs.
