Supplier due diligence: protecting your kitchen upstream

Because the food you receive and use is only as safe as the suppliers who provide it - so your kitchen's food safety depends on the safety of what comes in. Food safety is often thought of as what happens in the kitchen (handling, cooking, hygiene), but the food arrives from suppliers, and its safety on arrival depends on how it was produced, handled, stored and transported before it reached you. So if a supplier provides unsafe food (contaminated, from poor food-safety practices, wrongly stored or transported, or mislabelled), that unsafe food enters your kitchen. And unsafe food coming in is a serious problem, because no amount of good practice in your kitchen fully compensates for it: your good handling may not make contaminated food safe (some contamination cannot be cooked out, mislabelled allergens are dangerous regardless, and unsafe food is a risk you bear). So your kitchen's food safety genuinely depends on the safety of what comes in - which depends on your suppliers. This is why food safety starts upstream, with the suppliers, and why protecting your kitchen requires supplier due diligence (protecting it at the supply source), not just good kitchen practice. So your food is only as safe as your suppliers - safety starts upstream. This is general commentary, not legal advice.

A reputable, reliable supplier with good food-safety standards - one you can trust to provide safe, properly-handled food. A good supplier provides food that is safe: produced, stored and transported safely (good food-safety practices through their operation), correctly labelled (accurate labelling, important for allergens and more), and from a sound, reputable operation. Established, reputable food suppliers - whose business depends on their food safety and reputation - generally have good food-safety standards and can be relied upon to supply safe food. So a good, safe supplier is a reputable, reliable one with sound food-safety standards, whom you can trust. Using such suppliers means the food coming into your kitchen is from a safe source, protecting your kitchen at the start of the chain. Conversely, unknown, dubious or poor suppliers risk unsafe food (contaminated, poorly handled, mislabelled) coming in - so who you buy from matters greatly to your food safety. So choose your suppliers with food safety in mind - reputable, sound, reliable suppliers you can trust - not just on price or convenience, and especially avoiding dubious, cheap, or unknown sources where the food safety is uncertain. So a good, safe supplier is reputable, reliable, and has good food-safety standards. This is general commentary.

Taking reasonable care to satisfy yourself that your suppliers are safe and reputable - checking who you buy from, rather than buying from just anyone unchecked. It involves: using established, reputable suppliers (choosing suppliers with good standards and reputation, whose food safety you can have confidence in); and, appropriately to the supplier and the risk, checking their food-safety credentials (satisfying yourself they operate to good food-safety standards - which reputable suppliers can demonstrate, e.g. through their food-safety accreditations, certifications or standards). So you take reasonable steps to check your suppliers are safe and reputable. The extent of the checking can be proportionate to the supplier and the risk: for established, well-known reputable suppliers, their reputation may give the assurance; for other suppliers or higher-risk supplies, more checking of their food-safety credentials may be warranted. The principle is to exercise due diligence - reasonable care over your suppliers' safety - so you are not buying from unsafe or unknown sources without any check. This protects against unsafe food from a poor source, and is part of your food-safety responsibility (and can matter legally). So supplier due diligence is checking, proportionate to the risk, that your suppliers are safe and reputable. This is general commentary; the appropriate due diligence depends on the supplier and supply.

For traceability and to show you exercised due diligence - both important parts of food safety. Traceability: keeping records of your suppliers (who you buy from, and what) - and more broadly being able to trace where your food came from - is important because if there is ever a problem (a contamination, recall, or issue traced to a supply), you can trace the food back to its supplier, which is essential for dealing with the problem (identifying the source, withdrawing affected food). Traceability is a food-safety requirement and a practical necessity, so keeping supplier records supports it. Showing you exercised due diligence: keeping records of your due-diligence checks and the assurances you have (your suppliers' food-safety credentials, certifications, or other evidence) provides evidence that you took reasonable care over your suppliers - part of your food-safety responsibility, and potentially important legally (the 'due diligence' defence in food-safety law rests on showing you took all reasonable precautions and exercised all due diligence, of which checking and record-keeping over your suppliers is part). So keeping records lets you demonstrate you did what you should. So keep records of your suppliers (for traceability) and your due-diligence checks (to show you exercised due diligence) - an important part of protecting your kitchen upstream. Follow food-safety guidance on traceability and records. This is general commentary, not legal advice.

Traceability is being able to trace where your food came from - to identify the supplier and source of the food you have. It matters for food safety because, if there is ever a problem with food (a contamination, a recall, an illness traced to a food, or a supply issue), traceability lets you trace the affected food back to its source (the supplier, batch, delivery) - which is essential for dealing with the problem: identifying where the unsafe food came from, withdrawing or recalling affected food, and stopping the problem. Without traceability, you could not tell where suspect food came from or what else might be affected, making it very hard to deal with a problem safely. So traceability - knowing where your food came from, supported by keeping records of your suppliers and supplies - is a food-safety requirement and a practical necessity. It is part of supplier due diligence and food-safety records: keeping records of your suppliers (and being able to trace your food) so that, if needed, you can trace food back to its source. So traceability matters because it lets you trace and deal with a food problem back to its source - an essential food-safety capability that keeping supplier records supports. So keep the records that give you traceability of your food. This is general commentary; follow food-safety guidance on traceability.

It complements it - supplier due diligence protects your food safety upstream (at the supply source), and the food safety in your kitchen protects it in the kitchen, the two together keeping the food safe from source to service. Safe food coming in (from good suppliers, via due diligence) is the necessary foundation, and safe handling in the kitchen (good food-safety practices, temperature control, hygiene, allergen management, and a genuinely clean kitchen) builds on it. Neither alone is enough: unsafe food coming in undermines even good kitchen practice (you cannot always make unsafe incoming food safe), and even safe incoming food can be made unsafe by poor kitchen handling - so both the upstream (suppliers) and the in-kitchen (handling and hygiene) food safety are needed. So supplier due diligence works together with your kitchen's food safety, the two making up your overall food safety. And the in-kitchen food safety rests on good practices and a genuinely clean kitchen - so keeping the kitchen genuinely clean (routine and periodic deep cleaning) is part of the in-kitchen food safety that complements the upstream supplier due diligence. So protect your food safety both upstream (supplier due diligence) and in the kitchen (safe handling, hygiene, a clean kitchen) - the two together keeping the food safe. This is general commentary.
