Food Industry – Risk and Loss Prevention

Expert-reviewed Updated: 2026-09-01 Expert-reviewed: 2026-09-04 (Guido Hesse, Hesse Group Holding AG) Version 0.1.0

The food industry combines dust explosion, cooking-oil fire and ammonia refrigeration risk with strict hygiene and traceability requirements, closely linking loss prevention and product liability exposure.

Risk drivers

Processing steps such as milling, drying and conveying flour, sugar or milk powder generate combustible dust that poses a significant explosion risk inside enclosed vessels and silos. Frying and baking processes involving hot fats and oils are also a frequent fire cause, while the ammonia refrigeration systems widely used for chilled and frozen products bring their own release and explosion risk. In addition, production interruptions can quickly result in total losses of perishable raw materials and semi-finished goods.

Protection measures

Industry-typical measures include explosion protection concepts for silos, mills and pneumatic conveying systems, grease-fire suppression in kitchen and frying areas, a systematic maintenance and leak-monitoring programme for ammonia refrigeration plant, and strict separation of clean and unclean zones to prevent cross-contamination. Hygiene requirements and loss prevention are closely intertwined here, as structural measures frequently serve both objectives at once.

Insurance relevance

Beyond property damage, the combination of business interruption and product liability exposure is of central importance for food businesses, since a contamination event can trigger recall costs and reputational damage far exceeding the immediate physical loss. Insurers reviewing the risk pay particular attention to the condition of refrigeration plant, dust management and documentation of the operational hygiene concept.
