PFA Level-1 Food Safety cheat sheet

Food safety hazards are classified into four groups: biological (bacteria, viruses, parasites, moulds), chemical (cleaning agents, pesticides, heavy metals), physical (glass, metal, stone, bone), and allergenic.

The danger zone is 5 °C to 63 °C; bacteria multiply fastest between 20 °C and 50 °C, so keep high-risk food below 5 °C or above 63 °C.

In the temperature danger zone bacteria can double roughly every 20 minutes under ideal conditions, so 2 hours at ambient is the practical cumulative limit for high-risk food.

High-risk foods are those that are moist, protein-rich and near-neutral pH: cooked rice, meat, poultry, dairy, eggs, seafood, gravies, and cut fruit.

Low-risk foods are dry, highly acidic, heavily sugared or heavily salted: dry flour, sugar, vinegar, pickles, and dry biscuits.

The five key controls are: keep clean; separate raw and cooked; cook thoroughly; keep food at safe temperatures; use safe water and raw materials.

Cross-contamination is the transfer of hazards from raw to ready-to-eat food via hands, utensils, boards, cloths, drips, or packaging.

Cleaning removes visible soil; disinfection reduces microorganisms to a safe level - surfaces must be cleaned before they are disinfected, since soil protects microbes.

A food handler is anyone who works with unpacked food or food-contact surfaces, and is legally bound to report certain illnesses and symptoms to the person in charge.

Bacterial foodborne illness is either infection (living cells colonise the gut, e.g. Salmonella) or intoxication (pre-formed toxin is swallowed, e.g. Staphylococcus aureus, Bacillus cereus).

Staphylococcus aureus toxin is heat-stable: reheating does not destroy it, and it is commonly introduced by hand contact to cooked foods kept warm.

Bacillus cereus has two forms: a heat-stable emetic toxin in cooked rice left at room temperature, and a heat-labile diarrhoeal toxin in meat and vegetables.

Clostridium perfringens causes illness via toxin produced in the gut after eating stews, gravies and meats cooked in bulk and cooled slowly.

Clostridium botulinum is anaerobic and produces a neurotoxin in low-acid, low-oxygen, improperly canned or vacuum-packed foods; boiling destroys the toxin but not the spore.

Salmonella is associated with poultry, eggs, raw meat and unpasteurised milk, and is killed by thorough cooking to 74 °C core temperature.

Listeria monocytogenes grows at refrigeration temperature, survives freezing, and is a particular risk in ready-to-eat chilled foods for pregnant women, the elderly and immunocompromised people.

Escherichia coli O157:H7 is linked to undercooked minced beef and raw milk, has a very low infectious dose, and can cause haemolytic uraemic syndrome.

Adulteration is the addition of a foreign or inferior substance to food - for example water in milk, chalk or starch in flour, or non-permitted colour in spices - and is a legal offence distinct from spoilage.

Handwashing steps: wet hands, apply soap, rub palms, backs, between fingers and under nails for at least 20 seconds, rinse, then dry with a single-use towel or air dryer.

Hands must be washed on entry to the kitchen, after toilet use, after handling raw meat or eggs, after touching the face or hair, after waste handling, and after cleaning chemicals.

Exclude a food handler from food areas when they have vomiting, diarrhoea, jaundice, fever with sore throat, or an infected skin lesion on exposed skin; require clearance before return.

A food handler with diarrhoea must not return to food handling until at least 48 hours after symptoms stop.

Correct protective clothing: clean light-coloured or designated uniform, hair restraint covering the scalp and hair, no nail varnish or false nails, no wrist jewellery or watches, and no strong perfume.

Personal items - mobile phones, cigarettes, money, and street clothes - must not enter food preparation areas; store them in a designated locker outside the kitchen.

Colour coding of chopping boards reduces cross-contamination: red for raw meat, blue for raw fish, yellow for cooked meat, green for salad and fruit, brown for vegetables, white for dairy and bakery.

Refrigerator rules: store raw meat and poultry below ready-to-eat food, keep cooked food covered and labelled with date, and do not overload - cold air must circulate.

Pest control requires proofing (mesh screens, door sweeps, sealed gaps), waste in lidded bins emptied frequently, no standing water, and a documented pest-control schedule.

The Punjab Food Authority regulates food businesses across Punjab under the Punjab Food Authority Act 2011, with rules and regulations made under that Act.

A food business must hold a valid PFA licence before commencing operations; operating without one is an offence attracting penalty and possible sealing of the premises.

Licence categories are tiered by scale and risk - typically a small-scale registration or licence for small units, and higher-tier licences for medium and large manufacturers, hotels and chains.

A licence is premises- and activity-specific: it names the address, the food category and the business activity, and a change of address, ownership or activity requires an amendment or fresh application.

A licence is time-limited and must be renewed before expiry; continuing to trade on an expired licence is treated as operating without a licence.

The application is accompanied by the prescribed fee, proof of identity and ownership or tenancy of the premises, and premises details sufficient for inspection.

PFA inspectors may enter and inspect premises, take samples, examine records, and seize or seal food and equipment suspected of being unfit or adulterated.

A licence may be suspended or cancelled for serious or repeated violations, for adulteration, or for failing to comply with an improvement notice within the stated period.

Display of the licence at the premises and maintenance of traceability and hygiene records are ongoing conditions of holding the licence, not one-time requirements.

A complaint may be lodged with PFA by a consumer, by telephone, in writing, or through the PFA's designated complaint channels, and is logged with the complainant's details and the food business concerned.

A valid complaint identifies the food business, the product or premises, the nature of the problem, and the date - anonymous complaints may be recorded but are harder to act on.

After a complaint, the inspector conducts a visit, records findings against the relevant hygiene and food-safety requirements, and may take a formal sample for laboratory analysis.

Sampling follows a defined procedure: the sample is divided into portions, sealed and labelled, one portion left with the business, and a receipt or memo issued; a chain of custody is maintained.

Laboratory analysis determines whether the sample is adulterated, misbranded, substandard, or unfit for human consumption, and the report is the evidential basis for further action.

Enforcement is graduated: verbal guidance, then a written improvement notice with a compliance deadline, then penalty, prosecution, sealing, or licence suspension for persistent or serious breaches.

A food business served with a notice has a right to be heard and to appeal through the prescribed forum within the stated time; ignoring a notice is itself a separate violation.

Compliance records to retain include cleaning schedules and sign-off sheets, temperature logs, pest-control reports, staff training and medical records, supplier and traceability records, and calibration certificates.

An effective internal complaint response is to investigate promptly, correct the cause, document corrective action, and verify that the corrective action worked.

Cooking targets: poultry and rolled roasts to 74 °C core; minced meat and sausages to 71 °C; whole cuts of beef and lamb may be served rarer but surface must be seared.

Reheating must reach 74 °C throughout and be done once only; never reheat food more than once.

Cooling cooked food must pass 63 °C to 5 °C within 90 minutes; divide into shallow containers and use rapid cooling, not room-temperature standing.

Hot holding must keep food at or above 63 °C; cold holding at or below 5 °C; frozen storage at or below −18 °C.

Thaw food in a refrigerator at 5 °C or below, under running potable water, or in a microwave for immediate cooking - never on a bench at room temperature.

A probe thermometer must be cleaned and disinfected between readings, and its accuracy verified - typically in ice water at 0 °C and boiling water at 100 °C.

Freezing does not kill bacteria; it only stops their growth, so frozen raw food must be treated as contaminated after thawing.

Chemical hazards include cleaning and sanitising chemicals, pesticides, veterinary residues, non-food-grade lubricants, and excessive or banned food additives.

Chemical contamination is prevented by storing chemicals away from food in labelled containers - never in drinks bottles or unlabelled sprayers.

Physical hazards include glass, hard plastic, metal fragments, stones, bones, jewellery, plasters and packaging clips; controls are breakage logs, metal detection, and no-glass policies in production areas.

The 14 major allergens include cereals containing gluten, crustaceans, eggs, fish, peanuts, soybeans, milk, tree nuts, celery, mustard, sesame, sulphites, lupin and molluscs.

Allergen control requires separated storage, dedicated or thoroughly cleaned utensils, and accurate ingredient information for every dish served or sold.

An allergic reaction can occur from trace amounts; 'may contain' labelling is a risk statement, not a substitute for proper allergen management.

Mycotoxins such as aflatoxin arise from mould growth on stored nuts, grains and spices, and are not removed by normal cooking.

The six stages of cleaning: pre-clean (remove debris), main clean with detergent, rinse, disinfect, final rinse where required, and dry.

Detergents remove grease and soil; disinfectants kill microbes; sanitisers do both in one product - a two-in-one sanitiser is used only on already visibly clean surfaces.

Disinfectant contact time must be respected; a surface wiped dry immediately after spraying has not been effectively disinfected.

Cleaning chemicals must be diluted per the manufacturer's instructions and stored below food preparation surfaces, never above them.

Waste must be held in lidded, leak-proof bins, removed frequently, and never stored in food preparation or storage rooms overnight.

Food-contact surfaces must be cleaned and disinfected after each use and between different food types, especially after raw meat.

A cleaning schedule records what is cleaned, by whom, how often, with what chemical and at what concentration, and is signed off after each task.

An inspection typically checks: valid licence displayed, premises structure and pest proofing, water supply, handwash facilities with soap and drying, refrigeration temperatures, staff hygiene and medical certificates.

Food handler medical certificates are required and must be current; an expired certificate is a routine inspection finding.

The inspector must be given access and cooperation; refusing entry, obstructing sampling, or concealing records is itself an offence.

Records commonly requested: licence, training records, medical certificates, temperature logs, cleaning schedules, pest control reports, supplier records and water test reports.

A notice issued at inspection states the violation, the required corrective action, and the compliance deadline; the business must respond in writing by that deadline.

Non-compliance with a notice escalates to penalty, prosecution, premises sealing, or licence suspension or cancellation.

Traceability requires that the business can identify, one step back and one step forward, the source and destination of each food batch.

A consumer who suspects adulteration or unhygienic handling may complain to PFA, and may also pursue a claim under consumer protection law.

The complainant should retain evidence - the product, packaging, batch or date code, receipt, and photographs - since the sample link is central to any action.

A complaint should be made promptly; delay weakens both the evidential value and the ability to trace the batch.

The business's own complaints log should record the complaint, investigation, root cause, corrective action and closure date.

Complaints are also a compliance signal: repeat complaints on the same product or premises indicate a systemic failure rather than an isolated error.

A complainant is entitled to be informed of the outcome of the investigation, subject to the authority's procedures.

False or malicious complaints are themselves actionable, so complaints should be truthful, specific and evidence-based.
