Food Safety & Hygiene Vocabulary in English

Contamination is when any harmful substance — bacteria, chemicals, physical objects, or allergens — enters food. Cross-contamination is the specific transfer of bacteria or allergens from one food or surface to another — for example, using the same chopping board for raw chicken and salad without washing it in between. Cross-contamination is one of the most common causes of food poisoning outbreaks in professional kitchens.

HACCP stands for Hazard Analysis and Critical Control Points. It is a systematic, science-based approach to identifying potential food safety hazards and establishing controls at the points in the production process where those hazards can be prevented, eliminated, or reduced to a safe level. HACCP is required by law for all food businesses in the UK and EU, and forms the basis of most food safety training programmes.

Sterilisation destroys all microorganisms including heat-resistant spores, typically using very high temperatures or pressure. It produces a sterile product with a long shelf life but can affect taste and nutrients. Pasteurisation uses lower temperatures — typically 72°C for 15 seconds for milk — to kill most pathogens while preserving more of the food's original flavour and nutritional value. Pasteurised products still require refrigeration.

An allergen is a substance that causes an allergic reaction in sensitive individuals. UK law requires the 14 major allergens to be declared on food labels and menus. These include cereals containing gluten, nuts, dairy, eggs, fish, shellfish, peanuts, sesame, soya, mustard, celery, lupin, molluscs, and sulphur dioxide. Failing to declare allergens correctly can be life-threatening and is a serious legal offence.

Traceability is the ability to track any food product through every stage of the supply chain — from the farm where it was grown, through processing and packaging, to the point of sale. If a contamination problem or mislabelling issue is discovered, traceability enables a fast, targeted recall of only the affected batches, minimising waste and protecting consumers.

Most perishable foods must be stored at or below 5°C (41°F). The danger zone — where bacteria multiply most rapidly — is between 5°C and 63°C. Hot food being held for service must be kept at or above 63°C. Cooked food being cooled must pass through the danger zone as quickly as possible and reach 5°C within 90 minutes.

Spoilage is the natural deterioration of food caused by microorganisms, enzymes, or chemical reactions — it makes food unpleasant to eat (off smells, slimy textures, mould) but does not always indicate the presence of dangerous pathogens. Contamination introduces harmful bacteria or substances that can cause illness even when the food looks and smells completely normal. You cannot always tell contaminated food by appearance alone.

PPE stands for Personal Protective Equipment — the protective clothing and equipment worn by food handlers to prevent contamination of food and protect the worker. In food environments, PPE typically includes disposable gloves, hairnets or head coverings, aprons, and sometimes face coverings and steel-toed footwear. Requirements vary by food type and environment and are covered by food hygiene regulations.

Food safety and workplace health topics appear in IELTS General Training Reading and Listening, typically in workplace, public health, or instruction-text formats at B1–B2 level. Cambridge B1 and B2 reading and listening tasks also include scenarios set in professional food environments, where understanding terms like temperature, storage, and hygiene is important.

Flash Cards are ideal for memorising definitions of technical terms like HACCP and pasteurisation. Wordsearch and Hangman reinforce spelling. Reading UK Food Standards Agency (FSA) guidance documents, food hygiene training materials, and the NHS Eatwell Guide online shows these terms in authentic regulatory contexts and helps prepare for both exams and workplace training.
