A meat thermometer with a dial. Notice the markings for each type of meat

A meat thermometer is a thermometer used to measure the internal temperature of meat, especially roasts and steaks, and other cooked foods. The degree of "doneness" of meat correlates closely with the internal temperature, so that a thermometer reading indicates when it is cooked as desired. Meat should always be cooked so that the interior reaches a temperature sufficient to kill pathogens that may cause foodborne illness; the thermometer helps to ensure this.

Characteristics

A meat thermometer has a metal probe with a sharp point which is pushed into the meat, and a dial or digital display. Some show the temperature only; others also have markings to indicate when different kinds of meat are done to a specified degree (e.g., "beef medium rare").

Meat thermometers are usually designed to have the probe in the meat during cooking. Some use a bimetallic strip which rotates a needle which shows the temperature on a dial; the whole thermometer can be left inside the oven during cooking. Another variety commonly used on turkey is the pop-up timer, which uses a spring held in by a soft material that "pops up" when the meat reaches a set temperature.

Other types use an electronic sensor in the probe, connected by a flexible heat-resistant cable to a display. The probe is inserted in the meat, and the cable comes out of the oven (oven seals are flexible enough to allow this without damage) and is connected to the display. These types can be set to sound an alarm when the specified temperature is reached. Wireless types, where the display does not have to be close to the oven, are also available.

Use

The probe can be inserted into the meat before starting cooking, and cooking continued until the desired internal temperature is reached. Alternatively the meat can be cooked for a certain time and taken out of the oven, and the temperature checked before serving. The tip of the probe should be in the thickest part of the meat, but not touching bone, which conducts heat and gives an overestimate of the meat temperature.

Poultry: Insert the meat thermometer into the thigh, but do not touch the bone. The suggested temperature for a turkey to be before it is safe to consume is 180-185 degrees Fahrenheit. If the turkey is stuffed, the temperature in the center of the stuffing should be about 160 degrees Fahrenheit.

Beef, Lamb, or Pork: Insert the meat thermometer away from bone, fat, or cartilage. A safe temperature to cook at is about 160-165 degrees Fahrenheit.

Ground meat, casseroles, and eggs: Insert the thermometer into the thickest area.
