Thermometers essential tools for food safety

Thermometers essential tools for food safety

January 11th, 2017 by Carla Haley Hadley in Features

Kitchen thermometers are a kitchen tool everyone should have in their utensil drawer and use regularly. They are essential when cooking meat, poultry and egg products to prevent undercooking, know that your food has reached a safe minimum internal temperature, and also to prevent foodborne illness.

It is the only reliable way to determine that your meat, poultry and egg products are cooked to the correct temperature. Most pathogens are destroyed between 140F and 165F.

Unfortunately, research shows that many consumers judge the color of the food to see if it is done instead of using the most reliable method of a thermometer. Some say they go by recommended cooking times, and trust their experience and judgment. This can be misleading and wrong. Let's look at cooking hamburgers, for instance. One out of four hamburgers turn brown in the middle before reaching a safe internal temperature of 160 degrees F, so color isn't always the best indicator.

So how do you decide what thermometer is best for you? There are numerous reliable thermometers on the market today; many which are inexpensive. Digitals, instant-reads, probes for the oven and microwave, disposable indicators and sensor sticks, pop-ups, and even barbecue forks are everywhere. They are high-tech and easy to use.

The Dial Oven-Safe thermometer reads in 1-2 minutes. Place it 2 to 2 1/2 inches deep into the thickest part of the food. It is generally used in roasts, casseroles and soups. This thermometer is safe to leave in the food while cooking.

The Digital Instant-Read gives a reading in 10 seconds. Place at least 1/2-inch deep, away from the bone. This one can be used to measure both thick foods such as roasts and thin foods such as soups. It is not designed to remain in the food during the cooking process.

Convenient for grilling is the Thermometer-Fork Combination. It reads in 2 to 10 seconds. Place at least 1/4-inch deep into the thickest part of the food. It can be used in most foods, but is not meant to remain in foods while it is cooking.

The Dial Instant-Read reads in 15-20 seconds. Place it 2 to 2 1/2 inches deep into the thickest part of the food. The temperature is averaged along the probe, from the tip to 2 or 3 inches up the stem; therefore, it must be inserted sideways. It can be used in roasts, casseroles, and soups

A pop-up thermometer is commonly used in turkeys and roasting. These one-time use thermometers pop up when the food reaches final temperature for safety and doneness. It is recommended to check the temperature in other parts of the food with a conventional thermometer as well.

Using a food thermometer is the only sure way of knowing if your food has reached a high enough temperature to destroy food borne bacteria.

So the next time you are wondering if something is done, reach for the thermometer that works best for you.
