Which Food Is Considered a TCS Food

Food safety is one of the most critical responsibilities in any kitchen, food business, or food service operation. Whether you run a restaurant, manage a catering service, operate a food truck, or simply want to understand food safety better, you will often hear the term TCS food. Knowing which food is considered a TCS food is essential for preventing foodborne illnesses, complying with food safety laws, and protecting public health.

This in-depth guide explains what TCS food means, which foods fall into this category, why they are risky, and how they should be handled safely. By the end, you will have a clear and practical understanding of TCS foods and their importance in food safety systems.

What Does TCS Food Mean?

TCS stands for Time/Temperature Control for Safety. A TCS food is any food that requires careful control of time and temperature to prevent the growth of harmful microorganisms, the formation of toxins, or the growth of pathogens that can cause foodborne illness.

In simple terms, TCS foods are foods that bacteria love. When these foods are kept in the “danger zone” for too long, bacteria can grow quickly and reach unsafe levels.

The Temperature Danger Zone

The temperature danger zone is generally defined as:

• 41°F to 135°F (5°C to 57°C)

When TCS foods are held within this range for extended periods, bacteria can multiply rapidly. That is why strict time and temperature controls are required for these foods during storage, preparation, cooking, cooling, and service.

Why TCS Foods Are High Risk

Not all foods pose the same level of risk. TCS foods are considered high risk because they usually have one or more of the following characteristics:

• High moisture content
• High protein content
• Neutral or slightly acidic pH
• Long holding times at warm temperatures

These conditions create an ideal environment for pathogens such as Salmonella, E. coli, Listeria monocytogenes, and Clostridium perfringens.

Understanding which food is considered a TCS food helps food handlers focus their safety efforts where they matter most.

Which Food Is Considered a TCS Food?

Below are the major categories of foods that are considered TCS foods according to widely accepted food safety guidelines, including FDA Food Code principles.

Raw and Cooked Animal Products

Animal-based foods are some of the most common and well-known TCS foods because they are rich in protein and moisture.

Meat

All types of meat are considered TCS foods, including:

• Beef
• Pork
• Lamb
• Goat
• Game meats

Both raw and cooked meat require strict temperature control. Raw meat can carry harmful bacteria, while cooked meat can support bacterial growth if not held at safe temperatures.

Poultry

Poultry is especially high risk and always considered a TCS food. This includes:

• Chicken
• Turkey
• Duck
• Goose

Poultry is commonly associated with Salmonella and Campylobacter, making proper cooking and holding temperatures essential.

Fish and Seafood

All seafood products fall under the TCS category, such as:

• Fish
• Shrimp
• Crab
• Lobster
• Mussels
• Oysters
• Clams

Seafood spoils quickly and supports bacterial growth if temperature control is lost.

Eggs

Eggs are a classic example of a TCS food. This includes:

• Raw shell eggs
• Liquid eggs
• Cooked eggs (scrambled, boiled, fried)
• Egg-based dishes

Because eggs can carry Salmonella, they must be refrigerated and cooked properly.

Dairy and Milk Products

Milk-based foods provide an ideal environment for bacteria and are considered TCS foods unless specifically treated to be shelf-stable.

Milk and Cream

These include:

• Whole milk
• Skim milk
• Cream
• Half-and-half

Once opened, these products must be refrigerated and kept at safe temperatures.

Cheese

Most cheeses are TCS foods, especially:

• Soft cheeses (cream cheese, ricotta, brie, feta)
• Semi-soft cheeses

Some hard cheeses may be less risky, but in food service settings, cheese is typically treated as a TCS food.

Yogurt and Cultured Dairy Products

Even though yogurt is acidic, it still requires refrigeration and is considered a TCS food in most cases.

Cooked Plant-Based Foods

Not all plant foods are TCS foods, but once cooked, many become high risk.

Cooked Vegetables

Examples include:

• Cooked potatoes
• Cooked carrots
• Cooked beans
• Cooked rice

Cooking changes the structure of vegetables, increases moisture availability, and makes them more supportive of bacterial growth.

Cooked Grains and Pasta

These are commonly overlooked but are definitely TCS foods:

• Rice
• Pasta
• Quinoa
• Oats

Improperly cooled or held rice is a known cause of foodborne illness due to Bacillus cereus.

Cut Fruits and Vegetables

Whole fruits and vegetables are generally not TCS foods, but once cut, many become TCS foods.

Cut Melons

This includes:

• Watermelon
• Cantaloupe
• Honeydew

Once cut, the protective outer rind is removed, and the flesh becomes vulnerable to bacterial growth.

Cut Tomatoes

Fresh tomatoes become TCS foods after cutting because their pH and moisture levels can support pathogens.

Leafy Greens

Cut or chopped leafy greens such as:

• Lettuce
• Spinach
• Kale

These are considered TCS foods due to their increased surface area and moisture exposure.

Sprouts and Sprout Seeds

Sprouts are among the highest-risk TCS foods.

Examples include:

• Alfalfa sprouts
• Bean sprouts
• Clover sprouts

Sprouts are grown in warm, moist conditions that encourage bacterial growth, making them extremely sensitive to time and temperature abuse.

Cooked or Prepared Foods

Many prepared foods become TCS foods even if their individual ingredients were not high risk.

Soups and Stews

Soups and stews often contain meat, vegetables, and broth, making them ideal environments for bacteria if not held properly.

Sauces and Gravies

Examples include:

• Meat gravies
• Cream-based sauces
• Cheese sauces

These foods often stay warm for long periods, increasing the risk if temperatures are not monitored.

Casseroles and Mixed Dishes

Combination foods such as lasagna, curries, and stir-fries are always considered TCS foods.

Tofu and Soy-Based Products

Plant-based proteins can also be TCS foods.

Examples include:

• Tofu
• Soy milk
• Tempeh

These products contain high moisture and protein, which supports bacterial growth if not refrigerated.

Foods with Added Acidity or Reduced Water Activity

Some foods are modified to reduce risk, but not all modifications remove TCS status.

Foods with Added Acid

Examples:

• Pickled vegetables
• Acidified sauces

If properly acidified and tested, some of these foods may not be TCS, but many still require refrigeration in food service settings.

Foods with Reduced Water Activity

Foods like jams or dried foods may not be TCS, but once rehydrated or mixed with other ingredients, they can become TCS foods.

Examples of Non-TCS Foods for Comparison

Understanding non-TCS foods helps clarify which food is considered a TCS food.

Examples of foods that are generally not TCS foods include:

• Dry rice or pasta (uncooked)
• Bread and rolls
• Whole fruits and vegetables
• Peanut butter
• Honey
• Hard candies

These foods have low moisture, high sugar, or other properties that limit bacterial growth.

How TCS Foods Should Be Stored

Proper storage is essential to controlling risk.

Cold Holding

• Store TCS foods at 41°F (5°C) or below
• Use calibrated thermometers
• Avoid overcrowding refrigerators

Hot Holding

• Keep hot TCS foods at 135°F (57°C) or above
• Stir foods regularly to maintain even temperature

Time as a Control

In some cases, time can be used instead of temperature, but strict procedures must be followed, including labeling and discarding food after a set period.

Cooking and Reheating TCS Foods Safely

Minimum Internal Cooking Temperatures

Different TCS foods require different cooking temperatures, such as:

• Poultry: 165°F
• Ground meats: 155°F
• Seafood and whole cuts of meat: 145°F

Reheating

• Reheat TCS foods rapidly to 165°F
• Never reheat food slowly in hot holding equipment

Cooling TCS Foods Correctly

Improper cooling is one of the leading causes of foodborne illness.

Safe cooling guidelines include:

• Cool from 135°F to 70°F within 2 hours
• Cool from 70°F to 41°F within an additional 4 hours
• Use shallow containers, ice baths, or blast chillers

Labeling and Date Marking TCS Foods

Ready-to-eat TCS foods stored for more than 24 hours must be properly labeled.

Key points include:

• Label with preparation or opening date
• Discard after the maximum allowed storage time
• Rotate stock using FIFO (First In, First Out)

Why Knowing TCS Foods Matters

Understanding which food is considered a TCS food is not just about passing inspections. It helps to:

• Prevent foodborne illnesses
• Protect customers and staff
• Reduce food waste
• Maintain legal compliance
• Build trust with customers

Foodborne illness outbreaks can damage reputations, lead to legal action, and cause serious harm. Proper management of TCS foods is one of the most effective ways to reduce these risks.

Common Mistakes With TCS Foods

Some frequent errors include:

• Leaving cooked food at room temperature too long
• Improper cooling of large batches
• Failing to monitor temperatures
• Assuming plant-based foods are always low risk
• Not date-marking ready-to-eat foods

Avoiding these mistakes requires training, awareness, and consistent procedures.
