Use a thermometer and stick it in, not a knife

Bad food safety advice from Tesco Ireland today on Twitter:

@safefood_eu tip: To check meat is fully cooked, stick a sharp knife in & check that there is no pink meat in the middle #homecooks

barfblog.Stick It InColor is a lousy indicator. There’s lots of references on barfblog. Why stick in a knife when you can stick in a tip-sensitive digital thermomter?
