FAO Puts Food Safety at the Heart of Cutting Food Waste

Food safety is often treated as the final checkpoint before a meal reaches the table. A recent FAO update argues that it should be part of the food-waste conversation much earlier. In its 24 March 2026 report, the Food and Agriculture Organization described how contamination, poor handling and weak infrastructure can turn usable food into loss long before it reaches consumers.

The report followed a webinar held on 11 March by FAO’s Agrifood Systems and Food Safety Division. More than 550 people registered from around the world. Its central message was practical: food safety is not only a regulatory requirement or a response to an outbreak. Preventive hygiene and better controls can also help food remain suitable for sale, preparation and consumption.

Why unsafe food becomes waste

Food may be rejected, discarded or lose its value when it is contaminated or handled in a way that makes its safety uncertain. FAO’s speakers connected this problem to several points in the food chain, including farms, markets, transport and processing. That matters because preventing a loss at its source is usually more effective than trying to recover food after a safety failure has occurred.

The webinar highlighted examples of pesticide misuse that can lead to vegetables being rejected, poor hygiene contributing to losses in fish value chains, and contamination risks affecting crop quality and prices. These are not simply questions of appearance or consumer preference. Once a hazard makes food unsafe, keeping it out of the waste stream can conflict with the more basic duty to protect people from harm.

The food-safety and food-waste link is global

FAO’s regional examples showed that the problem looks different in different settings. In the Near East and North Africa, microbial contamination, pesticide residues and mycotoxins were identified as important drivers of rejection and trade losses. In Zambia and Colombia, the organization pointed to pesticide misuse and poor agricultural practices as contributors to both safety risks and production losses.

A separate project in Asian fruit and vegetable wholesale markets showed how better hygiene, waste management and infrastructure can address both problems at once. Cleaner facilities, improved handling and more reliable systems can reduce the chance that food becomes unsafe while also protecting its quality and value. FAO said it plans to explore this connection further through scientific analysis and policy work.

What the update means for home cooks

The webinar focused on food systems rather than issuing a new household rulebook. Still, its message translates well to everyday kitchens. The safest way to reduce waste is to make food-safety decisions before food becomes questionable, rather than trying to rescue it after uncertain storage or cross-contamination.

Plan portions before cooking. The FAO’s food-waste reduction guidance recommends serving smaller portions when appropriate and saving leftovers that can be stored safely. Cooked food that is clearly assigned to a later meal is easier to cool, cover and label than food left in a serving dish for hours.
Keep raw and ready-to-eat foods apart. Use clean utensils and surfaces for cooked food, salads and other items that will not receive further cooking. FAO’s Good Hygiene Practices toolbox explains that preventing biological, chemical and physical hazards is the foundation of safe food handling.
Make storage information visible. Move leftovers into clean, covered containers, mark what they are and when they were stored, and follow the storage instructions that apply in your location. Clear product information and intended-use instructions help consumers handle, prepare and store food safely.
Do not gamble with uncertainty. If you cannot verify how food was handled, whether it has been exposed to contamination or whether its storage conditions were safe, discarding it is the responsible choice. Saving food is worthwhile only when the safety decision is sound.

A useful shift in perspective

FAO’s report does not suggest extending shelf life or overriding a recall, use-by date or safety instruction. Its point is more straightforward: hygiene, clean equipment, appropriate storage and preventive controls can stop food from becoming waste in the first place. That is useful at every scale, from a wholesale market to a family refrigerator.

The timing also gives the update a longer shelf life of its own. FAO’s food-loss-and-waste platform points toward the International Day of Awareness of Food Loss and Waste on 29 September. For home cooks, the takeaway is immediate: waste reduction begins with buying and portioning realistically, but it only works when food remains safe throughout the journey from preparation to the next meal.
