Foodborne Illness Outbreak

A situation in which two or more people experience a similar illness after eating the same food, with laboratory or epidemiological evidence confirming the food as the source.

Related: Foodborne Illness, Hazard Analysis
Biological Hazard

A living organism or its toxin that can cause illness when present in food, including bacteria, viruses, parasites, and molds.

Related: Pathogen, Spore-Former
Chemical Hazard

A harmful substance that contaminates food unintentionally or through misuse, such as cleaning compounds, pesticides, toxic metals, or unapproved additives.

Related: Physical Hazard, Cross-Contamination
Physical Hazard

A hard or foreign object that can injure a person who eats the food, such as glass, metal fragments, bone, stones, or packaging materials.

Related: Chemical Hazard, Receiving Inspection
Pathogen

A microorganism capable of causing disease, including bacteria such as Salmonella and Listeria, viruses such as norovirus, and parasites.

Related: Biological Hazard, TCS Food
Spore-Former

A bacterium that can form a heat-resistant resting structure, allowing it to survive normal cooking and later grow in food held at unsafe temperatures.

Related: Temperature Danger Zone, Cooling
Temperature Danger Zone

The temperature range of 41°F to 135°F (5°C to 57°C) in which bacteria multiply most rapidly in food.

Related: TCS Food, Time as a Public Health Control
TCS Food

Food that requires time and temperature control for safety because it supports rapid bacterial growth, such as meat, poultry, dairy, cooked rice, and cut melons.

Related: Temperature Danger Zone, Cooling
Cross-Contamination

The transfer of harmful microorganisms or other contaminants from one food, surface, or utensil to another, often through direct contact or shared equipment.

Related: Cross-Contact, Sanitizing
Cross-Contact

The transfer of an allergen from a food containing it to a food that does not, typically through shared utensils, surfaces, or frying oil.

Related: Cross-Contamination, Allergen
Allergen

A protein in a food that triggers an immune reaction in sensitive individuals; major ones include milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soy, and sesame.

Related: Cross-Contact
Handwashing Sink

A sink designated and used only for washing hands, supplied with hot and cold running water, soap, and a means of drying hands.

Related: Hand Hygiene, Exclusion
Hand Hygiene

The practice of cleaning hands at proper times and in the proper way, including wetting, soaping, scrubbing, rinsing, and drying, to reduce contamination.

Related: Handwashing Sink, Glove Use
Glove Use

The practice of wearing single-use gloves over clean hands, changing them when soiled or torn and between tasks, as a supplement to rather than a substitute for handwashing.

Related: Hand Hygiene
Exclusion

A regulatory restriction that prevents a food employee diagnosed with or symptomatic for a communicable illness from working in food operations.

Related: Restriction, Food Employee Reporting Agreement
Restriction

A limitation placed on a food employee's duties so they avoid contact with food, utensils, and clean equipment while they may be carrying a communicable illness.

Related: Exclusion
Food Employee Reporting Agreement

A written document in which employees acknowledge their duty to report symptoms, diagnoses, and high-risk exposures to their person in charge.

Related: Exclusion, Person in Charge
Cooling

The process of bringing cooked food down quickly through the danger zone, typically from 135°F to 70°F within two hours and to 41°F within six hours total.

Related: Reheating, Temperature Danger Zone
Reheating

Raising previously cooked and cooled food to a safe internal temperature, generally 165°F for 15 seconds, before hot holding.

Related: Cooling, Hot Holding
Hot Holding

Maintaining cooked food at or above 135°F (57°C) to prevent bacterial growth until it is served.

Related: Cold Holding, Reheating
Cold Holding

Maintaining food at or below 41°F (5°C) to slow or stop the growth of microorganisms until it is used or served.

Related: Hot Holding, Temperature Danger Zone
Time as a Public Health Control

A written procedure allowing food to be held without temperature control for a limited time, provided it is marked and discarded or cooked when that time expires.

Related: Temperature Danger Zone, Active Managerial Control
Cleaning

Removing visible soil, food residue, grease, and other debris from a surface using detergent and mechanical action.

Related: Sanitizing, Three-Compartment Sink
Sanitizing

Reducing the number of microorganisms on a cleaned surface to safe levels using heat or an approved chemical sanitizer at the proper concentration and contact time.

Related: Cleaning, Test Strip
Test Strip

A paper or plastic strip used to measure the concentration of a chemical sanitizer solution so it stays within the required range.

Related: Sanitizing
Three-Compartment Sink

A sink setup with separate basins for washing, rinsing, and sanitizing equipment and utensils by manual immersion.

Related: Cleaning, Sanitizing
Backflow Prevention

A device or air gap that stops contaminated water from flowing backward into the potable water supply.

Related: Potable Water
Potable Water

Water that is safe to drink and use in food preparation, obtained from an approved source and protected from contamination.

Related: Backflow Prevention
Integrated Pest Management

A preventive approach to pest control that combines sanitation, exclusion, and monitoring, using pesticides only as a last resort under trained supervision.

Related: Pest Sighting Log
Pest Sighting Log

A record kept by the operation documenting observed pests, evidence of activity, and the corrective actions taken in response.

Related: Integrated Pest Management
Receiving Inspection

The check performed when deliveries arrive to verify temperature, packaging integrity, labeling, and condition before accepting food.

Related: Approved Supplier, Physical Hazard
Approved Supplier

A vendor that has been verified as meeting regulatory standards and can provide documentation, such as a letter of guarantee, for the foods it supplies.

Related: Receiving Inspection, Shellstock Tag
Shellstock Tag

A label attached to a container of live molluscan shellfish identifying the harvest area and date, which must be retained for 90 days after sale.

Related: Approved Supplier
Hazard Analysis

The first HACCP principle, in which a team identifies potential biological, chemical, and physical hazards and the steps needed to control them.

Related: Critical Control Point, Critical Limit
Critical Control Point

A step in the flow of food where a control measure can be applied to prevent, eliminate, or reduce a significant hazard to an acceptable level.

Related: Hazard Analysis, Critical Limit
Critical Limit

A measurable value, such as a temperature or time, that must be met at a critical control point to keep a hazard under control.

Related: Critical Control Point, Corrective Action
Corrective Action

The step taken when monitoring shows a critical limit was not met, including fixing the problem and handling the affected food safely.

Related: Critical Limit, Monitoring
Monitoring

Scheduled observation or measurement, such as taking temperatures, to confirm that critical limits at control points are being met.

Related: Corrective Action, Verification
Verification

Activities, other than monitoring, that confirm the food safety system is working as intended, such as record review, calibration checks, and internal audits.

Related: Monitoring, Active Managerial Control
Active Managerial Control

The operator's ongoing, deliberate system of procedures and oversight that actively prevents, eliminates, or reduces food safety hazards rather than reacting after problems occur.

Related: Person in Charge, Time as a Public Health Control
Person in Charge

The individual present during operations who is responsible for food safety, including supervising employees, monitoring temperatures, and enforcing hygiene and illness policies.

Related: Active Managerial Control, Food Employee Reporting Agreement
