Acceptable practices in a food facility are the daily habits and procedures that keep food safe from contamination, spoilage, and bacterial growth. They cover everything from how employees wash their hands to how food is stored, cooked, cooled, and served. Whether you’re preparing for a food safety certification or managing a kitchen, these are the core standards that health inspectors look for and that every food facility is expected to follow.
Handwashing Requirements
Proper handwashing is the single most important habit in any food facility. The FDA requires scrubbing with warm water and soap for at least 20 seconds. That applies before and after handling food, after using the restroom, after touching your face or hair, after handling raw meat, after taking out trash, and after any activity that could introduce bacteria to food contact surfaces.
A common violation is washing hands too briefly or skipping it between tasks. Switching from handling raw chicken to preparing a salad without washing in between is a textbook cross-contamination risk. Food facilities must have dedicated handwashing sinks that are stocked with soap and paper towels and kept separate from sinks used for food prep or dishwashing.
Temperature Control and the Danger Zone
Bacteria multiply fastest between 40°F and 140°F, a range known as the danger zone. In this window, bacterial populations can double in as little as 20 minutes. The rule is straightforward: never leave perishable food in the danger zone for more than two hours. If the room temperature is above 90°F, that window shrinks to one hour.
Cold foods must be held at 41°F or below. Hot foods must be held at 135°F or above. Every food facility should have calibrated thermometers available, and staff should be checking temperatures regularly rather than relying on guesswork.
Minimum Cooking Temperatures
Different foods require different internal temperatures to destroy harmful bacteria. These are non-negotiable minimums, measured with a food thermometer at the thickest part of the food:
- Poultry (whole birds, breasts, wings, legs, ground poultry, and stuffing): 165°F
- Ground meats (beef, pork, lamb): 160°F
- Fish and shellfish: 145°F
- Whole cuts of beef and pork: 145°F
Poultry has the highest required temperature because it carries a greater risk of salmonella and other pathogens. Ground meats need a higher temperature than whole cuts because grinding mixes surface bacteria throughout the meat. Relying on color or texture to judge doneness is not acceptable; a thermometer is the only reliable method.
Proper Food Storage Order
How you organize a refrigerator matters. The standard practice is to store foods based on the temperature they need to reach during cooking, with the highest-risk items on the bottom. From top to bottom, the correct shelf order is:
- Top shelves: Ready-to-eat foods, produce, and cooked dishes
- Middle shelves: Fish and eggs (cook temp: 145°F), then whole beef and pork (145°F)
- Lower shelves: Ground meat (cook temp: 155°F in commercial settings)
- Bottom shelf: Raw poultry (cook temp: 165°F)
This hierarchy prevents juices from raw meats dripping onto foods that won’t be cooked to a high enough temperature to kill those bacteria. Ready-to-eat items always go on top because they won’t undergo any further cooking before being served.
Two-Stage Cooling Process
Cooling cooked food is one of the most commonly mishandled steps in food facilities. Simply placing a large pot of hot soup in a walk-in cooler and hoping for the best is not acceptable. The FDA Food Code requires a two-stage process with specific time limits.
In the first stage, food must cool from 135°F down to 70°F within two hours. In the second stage, it must continue cooling from 70°F to 41°F or below within the next four hours. The total cooling time from start to finish cannot exceed six hours. Acceptable methods to speed cooling include using ice baths, dividing food into shallow pans, using a blast chiller, or stirring food in a container placed over ice.
The first stage is the most critical because the temperature range between 135°F and 70°F is where bacteria grow aggressively. If food hasn’t reached 70°F within two hours, it must be reheated and the cooling process started over, or the food must be discarded.
Safe Thawing Methods
Leaving frozen food on the counter to thaw at room temperature is one of the most common violations in food facilities. There are four acceptable thawing methods:
- In the refrigerator: The safest method, though it requires planning ahead since large items can take a full day or more.
- Under cold running water: The food must be submerged in cold tap water, with the water changed every 30 minutes to keep it cold.
- In the microwave: Only acceptable if the food will be cooked immediately afterward, since microwaving can create warm spots that enter the danger zone.
- Cooking from frozen: Skipping the thaw entirely and cooking food directly from its frozen state is safe, though cooking time will be longer.
Preventing Cross-Contamination
Cross-contamination happens when bacteria transfer from one surface or food to another. In a food facility, the most common source is raw meat coming into contact with ready-to-eat foods, either directly or through shared cutting boards, utensils, or hands.
Acceptable practices include using color-coded cutting boards (one for raw meat, a different one for produce), washing and sanitizing all equipment between uses, and storing raw proteins below ready-to-eat foods in the refrigerator. Wiping a cutting board with a towel between uses does not count as sanitizing.
Sanitizing Food Contact Surfaces
Cleaning and sanitizing are two separate steps. Cleaning removes visible food and grease. Sanitizing kills the bacteria that remain on a surface after cleaning. Both are required for any surface that touches food, including countertops, cutting boards, slicers, and utensils.
When using a bleach-based sanitizer, the solution must contain 50 to 100 parts per million (ppm) of chlorine. Too little won’t kill bacteria effectively; too much can leave harmful chemical residue on surfaces. Quaternary ammonium sanitizers are also widely used and must be diluted according to the manufacturer’s instructions. Test strips should be on hand to verify that sanitizer concentrations are within the correct range.
The standard process is wash, rinse, sanitize, and air dry. Towel-drying after sanitizing can reintroduce bacteria.
Dry Storage Standards
Non-perishable items like canned goods, flour, and dried grains need proper storage conditions too. The ideal temperature for dry storage is around 50°F for maximum shelf life, though 70°F is adequate for most products. Humidity should be kept low to prevent mold growth and packaging deterioration.
All dry goods must be stored at least six inches off the floor and away from walls to allow air circulation and to make pest inspections easier. Food should never be stored near chemicals, cleaning supplies, or other toxic materials. Once a package is opened, its contents should be transferred to a labeled, airtight container.
Employee Health Policies
Sick employees are a major source of foodborne illness outbreaks. Food workers are required to report certain symptoms and diagnoses to their manager before working with food.
Employees with vomiting or diarrhea must be restricted from working with exposed food, clean equipment, utensils, or linens. The same applies to workers with flu-like symptoms such as coughing, fever, sore throat, or a runny nose that cannot be controlled with medication.
Certain diagnosed illnesses require full exclusion from the facility. These include Salmonella, Shigella, E. coli O157:H7, Hepatitis A, Norovirus, and Entamoeba histolytica. Workers diagnosed with any of these must be reported to the local health department. Employees with open or infected wounds must also notify their manager so that proper precautions, like waterproof bandages and gloves, can be put in place.
Pest Management
Pests like cockroaches, rodents, and flies carry bacteria and contaminate food on contact. Acceptable pest control in a food facility follows an integrated pest management approach, which focuses on prevention rather than just reaction. This means eliminating the food, water, and shelter that pests depend on: keeping storage areas clean and clutter-free, sealing cracks and gaps in walls and doors, covering trash cans, and cleaning up spills immediately.
Signs of pest activity, such as droppings, gnaw marks, or nesting materials, should trigger immediate action. Chemical pesticides are a last resort and must be applied by a licensed professional in a way that does not contaminate food or food contact surfaces.
