A food worker’s core job is keeping food safe for every person who eats it. That means following specific rules around handwashing, temperature control, illness reporting, cleaning, and personal hygiene. Whether you’re preparing for a food handler exam or starting a new job in food service, here’s what you’re expected to do and why each step matters.
Wash Your Hands the Right Way
Handwashing is the single most important thing a food worker does to prevent contamination. Use warm water and soap, scrub for at least 20 seconds, and dry with a clean paper towel or air dryer. Twenty seconds is roughly the time it takes to hum “Happy Birthday” twice.
You need to wash your hands at these specific times:
- Before and after handling food
- After using the restroom
- After touching your face, hair, or body
- After sneezing, coughing, or using a tissue
- After handling raw meat, poultry, or seafood
- After taking out garbage
- After touching cleaning chemicals or dirty equipment
- After handling money or credit cards
Gloves are not a substitute for handwashing. You wash your hands first, then put gloves on. Every time you change gloves, you wash again.
Use Gloves Correctly
Single-use disposable gloves exist to prevent bare hand contact with ready-to-eat foods like salads, sliced fruit, bread, and anything that won’t be cooked again before serving. Wearing them does not mean you can skip handwashing or use the same pair all shift.
Change your gloves between every different task. If you’re doing the same task for a long stretch, swap them out at least every two to four hours. You also need a fresh pair after touching faucet handles, refrigerator doors, drawer handles, or any non-food surface. If a glove tears, rips, or gets visibly soiled, replace it immediately. Each glove change starts with washing your hands.
Keep Food Out of the Danger Zone
Bacteria multiply rapidly between 40°F and 140°F. This range is called the “danger zone,” and your job is to keep food out of it. Never leave perishable food at room temperature for more than two hours. If the surrounding temperature is above 90°F (think outdoor events or a hot kitchen near a loading dock), that window shrinks to one hour.
When cooking, use a food thermometer to verify that items reach their required minimum internal temperature:
- Poultry (whole birds, breasts, wings, thighs, ground poultry): 165°F
- Ground beef, pork, and other ground meats: 160°F
- Fish and shellfish: 145°F
- Leftovers and reheated foods: 165°F
Refrigerate perishable ingredients, including meat, seafood, dairy, cut fruit, and cooked leftovers, within two hours of preparation or receiving a delivery. Cold foods should stay at 40°F or below, and hot foods should be held at 140°F or above until served.
Report Illness Immediately
If you’re sick, you can easily spread pathogens to hundreds of people through the food you handle. Food workers are required to report certain symptoms to their manager before working with food:
- Diarrhea
- Vomiting
- Jaundice (yellowing of the skin or eyes)
- Sore throat with fever
- An open, infected wound
You must also report if you’ve been diagnosed with norovirus, Salmonella, Shigella, hepatitis A, or a strain of E. coli that produces dangerous toxins. These are the illnesses most commonly spread through food, and even a worker who feels mostly recovered can still be contagious.
After vomiting or diarrhea, you should stay home for at least 48 hours after symptoms completely stop. Your manager may require medical clearance before you return to handling food, depending on the diagnosis and your local health department’s rules.
Follow Personal Hygiene and Attire Rules
Federal regulations require food workers to remove all unsecured jewelry and any objects that could fall into food, equipment, or containers. Hand jewelry that can’t be adequately sanitized, like rings with stones or textured bands, needs to come off during food preparation. If a ring truly cannot be removed, it must be covered with a material that stays intact and sanitary.
Hair restraints are required wherever food is being prepared. This means hair nets, caps, headbands, or other effective coverings. Workers with facial hair need beard covers. The goal is straightforward: keep hair out of food. Clean uniforms or aprons, trimmed and clean fingernails, and no eating or smoking in food prep areas round out the basics.
Prevent Cross-Contamination
Cross-contamination happens when bacteria from raw food, dirty surfaces, or unwashed hands transfer to food that’s ready to eat. Preventing it comes down to separation and sanitation.
Store raw meat, poultry, and seafood on the lowest shelves of the refrigerator, below ready-to-eat items, so juices can’t drip onto other foods. Use separate cutting boards and utensils for raw proteins and produce. Never place cooked food on a plate or surface that previously held raw meat without washing and sanitizing it first.
Clean and Sanitize Surfaces Properly
Cleaning and sanitizing are two different steps, and both are necessary. Cleaning removes visible food and grease. Sanitizing kills the bacteria left behind. For food-contact surfaces like prep tables, cutting boards, and equipment, follow this sequence:
- Remove leftover food debris
- Rinse the surface to clear remaining residue
- Scrub with detergent
- Rinse again thoroughly
- Apply sanitizer according to the product’s directions
Sanitize surfaces after each use, between tasks involving different food types, and any time contamination could have occurred. In a three-compartment sink, dishes follow a similar process: wash, rinse, sanitize, then air dry.
Store Chemicals Away From Food
Cleaning supplies, sanitizers, and any toxic materials must be stored in a designated, secured area that is physically separated from food, food-contact surfaces, and food storage areas. Use spacing or a partition to keep them apart. Every chemical container needs a clear label identifying what’s inside.
First aid supplies and employee medications also stay away from food areas. If medicine needs refrigeration, store it in a covered, leak-proof container that can’t come into contact with food. Mixing up a spray bottle of sanitizer with a container of cooking liquid is a real risk in busy kitchens, and proper labeling and separation are the fix.
Respond to Emergencies Correctly
Certain situations qualify as “imminent health hazards,” and the required response is to stop serving food immediately. These include fires, floods, sewage backups, and the loss of electricity or water for two or more hours. In any of these situations, a food worker should stop operations and the manager must notify the local health authority right away.
If power or water goes out for less than two hours, you’re still responsible for protecting food safety during that window. That means monitoring food temperatures, keeping refrigerator and freezer doors closed, and discarding anything that enters the danger zone. Operations should not resume fully until the hazard is resolved and it’s safe to handle food again.
