Food Safety Glossary
This glossary explains the key food safety terms you will meet while studying for SITXFSA005 and SITXFSA006 in Australia. Understanding the language — not just memorising it — makes the rest of your study far easier, because most exam questions are really testing whether you understand these core concepts. Use it as a quick reference while you work through the study guide, the practice test or the flashcards. Each definition is written in plain English and links back to the topics that matter most for your assessment, from the temperature danger zone to HACCP and the role of a Food Safety Supervisor.
- Acidic food
- Food with a low pH (such as citrus, vinegar or pickles). High acidity slows the growth of most food-poisoning bacteria, which is why acidic foods are generally lower-risk.
- Allergen
- A substance that can trigger an immune reaction in some people. Australia requires priority allergens (peanuts, tree nuts, milk, egg, wheat/gluten, soy, sesame, fish, crustacea/molluscs, lupin and added sulphites) to be declared.
- Anaphylaxis
- A severe, rapid and potentially fatal allergic reaction. Even a trace of an allergen can cause it, which is why allergens cannot be “cooked out” and accurate ingredient information is critical.
- Approved supplier
- A supplier a food business trusts to provide safe food, often with agreed standards for transport temperature and traceability.
- Bacteria
- Microscopic single-celled organisms. Some are harmless or useful, but pathogenic bacteria such as Salmonella and Listeria cause food poisoning when allowed to multiply.
- Best-before date
- Indicates quality, not safety. Food may legally be sold after its best-before date if it is still fit to eat, unlike a use-by date.
- Biofilm
- A layer of bacteria that builds up and sticks to surfaces or equipment. It resists cleaning, which is why thorough cleaning before sanitising matters.
- Calibration
- Checking and adjusting a thermometer so it reads accurately — for example using iced water (0 °C) or boiling water (100 °C). Inaccurate probes give false confidence about temperature control.
- CCP (Critical Control Point)
- A step in a process where control is essential to prevent, eliminate or reduce a food safety hazard — cooking to 75 °C is the classic example.
- Chemical contamination
- Contamination of food by chemicals such as cleaning agents, sanitisers, pesticides or machine oil. Store chemicals well away from food.
- Cleaning
- Removing visible dirt, grease and food residue using detergent and water. Cleaning must happen before sanitising.
- Cold chain
- Keeping chilled food at or below 5 °C continuously from delivery through storage, preparation and display.
- Contamination
- The presence of anything harmful in food — biological (microbes), chemical, or physical (foreign matter).
- Corrective action
- The step taken when monitoring shows a critical limit has not been met — for example reheating, discarding food, or adjusting equipment.
- Critical limit
- A measurable boundary that must be met at a CCP, such as a minimum cooking temperature or a maximum time in the danger zone.
- Cross-contamination
- The transfer of harmful bacteria or allergens from one food, surface or person to another — commonly from raw food to ready-to-eat food.
- Danger zone
- 5 °C to 60 °C — the temperature range in which food-poisoning bacteria multiply most rapidly. Minimise the time food spends here.
- Decanting
- Transferring food from its original container into another. Decanted food should be labelled and dated to avoid confusion and to support FIFO.
- Detergent
- A cleaning agent that removes grease and dirt. It cleans but does not sanitise.
- Environmental Health Officer (EHO)
- A council or government officer who inspects food businesses, investigates complaints and enforces the Food Standards Code.
- FIFO (First In, First Out)
- A stock-rotation method where older stock is used before newer stock, reducing waste and the risk of using expired food.
- Food Act
- State and territory legislation that gives the Food Standards Code legal force and sets out offences and penalties for unsafe food handling.
- Food authority
- The state or territory body responsible for food regulation — for example the NSW Food Authority or Queensland Health.
- Food handler
- Anyone who works with food or food-contact surfaces — preparing, cooking, serving, packing, displaying or cleaning.
- Food poisoning
- Illness caused by eating contaminated food. Symptoms include nausea, vomiting, diarrhoea and cramps, and can be serious for vulnerable people.
- Food premises
- Any place where food is handled for sale. Premises must be designed and maintained to allow safe food handling (Standard 3.2.3).
- Food recall
- The removal of unsafe food from sale and from customers, coordinated with the relevant authority.
- Food safety program
- A documented, systematic plan (often HACCP-based) that identifies and controls food safety hazards in a business.
- Food Safety Supervisor (FSS)
- A trained, certified person responsible for overseeing food safety on site. Many businesses are legally required to have one; certification generally renews every five years.
- Food Standards Code
- The set of standards governing food in Australia and New Zealand, including Standards 3.2.2, 3.2.2A and 3.2.3 for food businesses.
- Foreign matter
- Physical contaminants such as glass, metal, plastic, hair or jewellery that should never end up in food.
- FSANZ
- Food Standards Australia New Zealand — the body that develops the Food Standards Code. It does not enforce it; that is done by states, territories and councils.
- Hazard
- Anything that could make food unsafe — biological, chemical or physical.
- HACCP
- Hazard Analysis and Critical Control Points — an internationally recognised, preventive food safety management system built on seven principles.
- High-risk food
- See Potentially hazardous food. Examples include cooked rice, meat, poultry, dairy, eggs, seafood and prepared salads.
- Hot holding
- Keeping hot food at 60 °C or above to keep it out of the danger zone while on display or service.
- Incubation period
- The time between eating contaminated food and the onset of food-poisoning symptoms — from hours to days depending on the pathogen.
- Listeria
- A bacterium that can grow even at refrigeration temperatures and is especially dangerous for pregnant women, the elderly and immune-compromised people.
- Microorganism
- A microscopic living thing — bacteria, viruses, yeasts and moulds. Some cause spoilage or illness.
- Mould
- A type of fungus that grows on food and can produce toxins. Visible mould usually means the food should be discarded.
- Pathogen
- A microorganism that causes disease, such as Salmonella, Campylobacter or E. coli.
- Personal hygiene
- The practices food handlers follow to avoid contaminating food — handwashing, clean clothing, covering cuts, and not working while ill.
- Pest
- An animal such as a rodent, cockroach, fly or bird that can contaminate food and spread disease.
- Physical contamination
- Contamination by foreign objects — glass, metal, hair, fingernails, packaging or jewellery.
- Potentially hazardous food (PHF)
- Food that must be kept at controlled temperatures to keep it safe because it supports the growth of pathogens or the production of toxins.
- Probe thermometer
- A thermometer used to measure the internal temperature of food. It must be clean, sanitised and calibrated.
- Ready-to-eat food
- Food that will be eaten without further cooking, such as salads, sandwiches and cooked meats — especially vulnerable to cross-contamination.
- Reheating
- Heating previously cooked food rapidly to 70 °C or hotter before hot holding. Food should only be reheated once.
- Salmonella
- A common food-poisoning bacterium associated with raw poultry, eggs and cross-contamination.
- Sanitise
- To reduce microorganisms on a clean surface to a safe level using heat or a chemical sanitiser, with the correct contact time.
- Sanitiser
- A chemical or heat method used to sanitise. It only works on a surface that has already been cleaned.
- Shelf life
- The length of time food remains safe and of acceptable quality under specified storage conditions.
- Single-use
- Items designed to be used once and discarded, such as paper towel or disposable gloves, to prevent cross-contamination.
- SITXFSA005
- The national unit “Use hygienic practices for food safety” — the core food handler competency.
- SITXFSA006
- The national unit “Participate in safe food handling practices” — associated with the Food Safety Supervisor role.
- Spore
- A dormant, highly resistant form some bacteria produce to survive heat and drying. Spores can survive cooking and grow later if food is mishandled.
- Staphylococcus aureus
- A bacterium often spread from hands, skin and noses to food, where it can produce a heat-stable toxin.
- Temperature control
- Keeping potentially hazardous food out of the danger zone by chilling, hot holding or cooking to safe temperatures.
- Thawing
- Defrosting frozen food safely — in the fridge or under controlled conditions, never left in the danger zone.
- 2-hour / 4-hour rule
- A guide for ready-to-eat PHF in the danger zone: under 2 hours total → refrigerate or use; 2–4 hours → use now; over 4 hours → discard.
- Toxin
- A poison produced by some bacteria or moulds. Many toxins are not destroyed by cooking, so prevention is essential.
- Use-by date
- A safety date. Food must not be sold or eaten after its use-by date because it may be unsafe.
- Virus
- A tiny infectious agent (such as norovirus or hepatitis A) that can spread through food via poor hygiene. Viruses do not grow in food but can be carried by it.
- Vulnerable populations
- Groups at higher risk from food poisoning — the elderly, young children, pregnant women and people with weakened immune systems.
- Yeast
- A type of fungus that can spoil food, especially sugary or acidic products.
- Zoonotic
- Describes a disease that can pass between animals and humans, relevant to handling raw meat, poultry and eggs.
