Which Food Must Be Received at 41 F (5 C)?

Which food must be received at 41 F (5 C)? Understanding the proper temperature control for safety (TCS) foods is crucial for preventing foodborne illnesses, and FOODS.EDU.VN offers comprehensive guidance on this topic. This article will provide a detailed look at TCS foods and the importance of maintaining the correct temperatures to ensure food safety, along with other considerations for handling food safely.

1. Understanding Time/Temperature Control for Safety (TCS) Foods

TCS foods, also known as potentially hazardous foods, are foods that require specific time and temperature controls to prevent the growth of pathogenic microorganisms or the formation of toxins. These foods provide the ideal environment for bacteria to thrive, making them more likely to cause foodborne illnesses if not handled correctly. It’s essential to maintain proper storage conditions and follow safety standards when dealing with TCS foods.

1.1. Defining TCS Foods

TCS foods generally include animal products that are raw or have been heat-treated, certain plant-based foods, and other items that support microbial growth. These foods require careful handling to remain safe. Some examples include:

• Animal Foods: Raw or heat-treated meat, poultry, fish, eggs, and dairy products.
• Plant-Based Foods: Cooked vegetables, cut melons, cut leafy greens, raw seed sprouts, and cut tomatoes.
• Other Foods: Garlic-in-oil mixtures, tofu, soy protein foods, and cooked rice.

1.2. Why Temperature Control is Critical

Maintaining TCS foods at the correct temperatures inhibits the growth of bacteria. Harmful microorganisms grow rapidly in the temperature danger zone, which is between 41°F (5°C) and 135°F (57°C). By keeping TCS foods outside this range, the risk of foodborne illnesses is significantly reduced. This is why refrigeration and hot holding are so important in food safety practices.

2. Receiving TCS Foods at the Correct Temperature

Receiving TCS foods at the correct temperature is the first line of defense against foodborne illnesses. When these foods arrive at a food service establishment, they must be checked immediately to ensure they meet the required temperature standards.

2.1. The 41°F (5°C) Rule

TCS foods must be received at 41°F (5°C) or lower to ensure they are safe to handle and store. This temperature helps to slow down the growth of bacteria. Any TCS food received above this temperature may be unsafe and should be rejected.

2.2. Exceptions to the Rule

There are a few exceptions to the 41°F (5°C) rule for receiving TCS foods. For example, milk can be received at 45°F (7°C) under specific conditions, such as being cooled to 41°F (5°C) within four hours. Shell eggs can also be received at an air temperature of 45°F (7°C). However, these exceptions must be strictly monitored and followed to prevent any potential health risks.

2.3. Using a Calibrated Thermometer

To accurately measure the temperature of TCS foods upon receiving, a properly calibrated thermometer is essential. The most common types of thermometers used are metal-stemmed, bi-therm thermometers, and thermocouples. Digital thermometers are also widely used and offer accurate readings.

To calibrate a bi-therm thermometer:

1. Locate the nut or holder beneath the dial face.
2. Place the thermometer stem in a glass of ice water.
3. Ensure the temperature reaches 32°F (0°C) or 33°F (0.5°C).
4. If it does not, adjust the needle by using pliers or a wrench on the nut to twist the dial face until it reads 32°F (0°C).

A digital thermometer is often pre-calibrated by the manufacturer but should be checked periodically for accuracy.

2.4. Proper Sanitization Practices

Before checking the temperature of any food, the thermometer stem must be sanitized to prevent cross-contamination. Use alcohol pads or sanitized cloths to wipe the stem thoroughly. This practice should be followed between each use and before checking different food items.
