There is a possibility that hot dogs may be contaminated with the harmful bacteria Listeria after they are produced. This bacteria multiplies in the fridge and if eaten by those at risk for food borne illness such as children, it can make them very sick. Hot dogs should be cooked until a thermometer inserted measures 74C/165F for two minutes. How long should it take to cook a turkey leg of 650 grams and at what temperature?  Thank you. The cooking time will be the time necessary for the internal temperature of the turkey leg, measured with a food thermometer, to reach 77 degrees C / 170 degrees F.  At that temperature, the turkey leg will be ready and safe to eat. I would like to know if a poached egg is better for your health when it is lightly poached, that is when the yolk is completely liquid instead of been firmly cooked like a hard boiled egg?  Thanks! It is recommend by Health Canada that eggs should be cooked or poached until teh yolk is firm to make sure that any harmful bacteria that could be present will be destroyed.  The eggs should be cooked until they reach a temperature of 63 degrees C / 145 degres F for 15 seconds.   That way, it will be safer for your health. I purchased 5 lbs of ground beef and immediately froze it. It has just finished thawing in the refrigerator and at this time still has ice crystals in it.
