The key to high food safety and reduced food waste

Published 2025-06-17

Tougher competition, increased customer demands and stricter legal requirements. The food industry is experiencing increased pressure from many directions. This makes it more important than ever to have accurate and reliable temperature measurement of food in all possible environments. This in turn helps to ensure high food safety and reduce food waste.

Food belongs on the plate – not in the bin

Billions of tons of food are wasted around the world every year. As much as one third of all food produced ends up in the garbage. This is an unnecessary waste of resources and money. Broken cold chains and improper storage are some common causes of food going bad and being thrown away too early. Estimates show that restaurants and supermarkets, for example, can cut their costs by up to 30% by reducing their food waste.

Key metrics for good food safety

Whether in incoming goods and warehouse management, or production and processing, two measurement parameters are important at several stages: temperature and pH. In many cases, these measurements have a crucial impact on food safety in terms of quality and shelf life of raw materials and food that are particularly sensitive.

By regularly measuring food temperatures, you can identify anomalies at an early stage and quickly take action to ensure an unbroken cold chain. This avoids the growth of bacteria and the need to throw away food, which can cost you a lot of time and money. We offer a wide range of measuring instruments for easy spot checks of temperature, pH and frying oil quality.

To keep raw materials fresh, ensure quality and maintain an unbroken cold chain, temperature monitoring is an effective and reliable tool. At the same time, it helps you meet current industry regulatory requirements. With Testo’s data loggers and smart monitoring systems, you can continuously monitor temperatures in transportation, warehouses, refrigerators, freezers, heating cabinets and production – both for internal follow-up and for regulatory requirements. This improves food safety and can help reduce food waste, saving money and benefiting the planet.

Popular calibration with food customers

By calibrating measuring equipment with us, you get answers to how “correct” measurement values your equipment shows compared to values from a highly accurate reference equipment. In the lab in Gothenburg, we perform accredited calibration of food instruments from all manufacturers. With quality assured methods, mostly standard calibration for the food industry is issued at the measuring points -18, ±0 and +60 °C (it is also possible to choose your own measuring points).

One service that is increasingly in demand is field calibration. Our calibration technicians from our offices in Gothenburg and Uppsala are constantly on the move, calibrating measurement equipment at customer sites – without disrupting their operations. Our field technicians calibrate everything from blast freezers at -30 °C to large baking ovens at +225 °C.

Field calibration of meters in transport

Properly tempered food transportation is important to maintain high quality and safety of raw materials and food even during longer shipments. Whether food transportation takes place during winter or summer. Requests from customers have led us to expand our offer to perform calibrations in transportation spaces on their premises. We calibrate both integrated sensors and mobile transport loggers – from all manufacturers – in road, rail, sea and air transportation. We see a clear trend: more and more people are realizing the value of reviewing and taking a holistic approach to food transport conditions.
