Time-Temperature Survey at a Restaurant that Specializes in Barbecued Food.

Temperatures of cuts of beef and pork, beef ribs, chicken, and brunswick stew were recorded during routine operations at a restaurant that specializes in barbecued food. Although surface temperatures reached 74 C (165 F) during barbecuing, internal temperatures did not. Internal temperatures, however, eventually reached 66 C (150 F) and remained above 60 C (140 F) for an hour or more.
