In order to properly measure the internal temperature of the food being cooked, all food thermometers must be properly inserted into the food to be inspected.
When using a dial thermometer, insert the long handle straight or obliquely into the thickest part of the food about two inches deep. Do not touch the bone or fat when inserting. The temperature is measured after about 15 seconds. Thinner foods such as hamburger, chicken breast, pork chops, etc. may need to be inserted from the side.
The long handle of the digital thermometer should be inserted straight or obliquely into the center of the thickest part of the food, about 1/2 inch deep, and do not insert bones or fat. The temperature can be measured in about five seconds. Digital thermometers are suitable for thin hamburger meat, chicken breast, smaller pieces of meat or poultry.
