Reliable food safety powered by Testo
The challenges of summer push food safety systems to their limits. Testo’s intelligent measurement solutions help you stay cool even under maximum pressure.
High heat, high pressure?
Master your summer challenges with ease!
Summer is coming – and with it, the toughest season for food safety and HACCP compliance in retail, logistics, and catering. Rising temperatures mean rising pressure across the entire cold chain: high heat pushes cooling systems to their limits, weak points become more critical, and food waste risks spike, while vacation-season staff shortages further strain daily operations. Still, performance has to be on point. Without exception.
Testo understands these specific summer challenges and helps food businesses maintain control, ensure food safety, and keep operations running reliably – even under peak performance pressure.
White paper „Relax in the summer heat – Identify risks before they arise using temperature mapping and monitoring"
Undetected temperature fluctuations in summer can significantly affect the indoor climate in warehouses, cold storage rooms, and loading areas. In our white paper, you’ll learn how temperature mapping and temperature monitoring can help you keep critical areas safe, and maintain optimal temperatures in your entire warehouse.
Summer challenge #1
Cold chain interruptions
Numerous handover points, different product groups, packaging types, and temperature requirements for fresh and frozen goods: the already complex cold chain is further strained by high summer temperatures. Short sections without active cooling – such as loading ramps, cross-docking facilities and delivery handover points – are particularly critical areas, as even brief waiting times in hot weather can compromise product safety. These weak points must therefore be avoided or passed through as quickly as possible. However, manual checks and paper-based documentation are often too slow to detect deviations in time, increasing the risk of spoilage, storage losses, or unsafe food.
With precise monitoring instruments, and digital checklists for incoming goods inspection, Testo reliably helps close temperature gaps, reduce human error, and keep the cold chain uninterrupted.
White paper “Stay cool – how your cold chain can withstand any inspection”
In this white paper, you will find practical information, tips, and tricks to help you identify weak points and potential sources of error in your cold chain, minimise risks through intelligent and practical measurement solutions, simplify your everyday workflows, and reduce food loss.
Summer challenge #2
Technical performance limits
High ambient temperatures put cooling units in vehicles, shelves, and warehouses under immense strain, as cooling capacities are typically not specifically designed for peak summer conditions. Increased external heat requires greater performance from refrigeration systems, elevating the risk of both overcooling and undercooling: overcooling leads to unnecessary energy consumption and potential product freezing, while undercooling increases the risk of food spoilage. When cooling systems have to work harder to maintain target temperatures, this often leads to uneven performance, higher operating costs, reduced efficiency, and potential losses in product quality.
By identifying weak points, critical locations, and optimal sensor placement, Testo’s temperature mapping solutions focus on systematic planning and preparation as the strategic basis for subsequent monitoring.
Why food retail uses Testo products
Testo's stationary monitoring solutions offer universal flexibility wherever reliable food safety is essential. Universally applicable, they adapt seamlessly to any number of measurement points, measurement parameters, and measurement environments – from retail storage and shelf presentation to food preparation. Our comprehensive range of devices, all connected via testo Smart Connect, covers various application scenarios for continuous temperature monitoring.
In retail, this delivers reliable 24/7 temperature control across critical cold chain areas – ensuring food safety, HACCP compliance, and operational efficiency even under summer heat pressure.
Summer challenge #3
Food waste
Rising summer temperatures significantly increase the risk of food spoilage across retail, logistics, and catering. As the weather heats up, the margin for error in food handling becomes much smaller: within the danger zone of 4 to 63 °C, bacterial growth accelerates rapidly, turning deviations that might be tolerable in winter into risky issues in summer. Without continuous cold chain monitoring, even slight temperature fluctuations can cause products to reach critical conditions and be discarded prematurely for safety reasons. Much of this costly food waste, however, is avoidable – with closer control, timely intervention, and seamless monitoring that helps protect product quality and safety.
With real-time temperature tracking, smart alerts, and automated documentation, Testo’s stationary monitoring solutions enable early detection of deviations in all temperature-sensitive processes.
