Researchers from EPFL have identified rubber-related chemicals in Swiss milk, raising new questions about how substances used in agricultural and food-production environments can enter the dairy supply chain.
The study investigated chemicals associated with rubber materials, including compounds that may originate from equipment, tyres and other rubber products used around farms and milk-production systems.
Chemicals Detected in Milk
The research highlights the ability of modern analytical techniques to detect trace-level contaminants that may otherwise remain unnoticed during conventional food-safety monitoring.
The findings are relevant to dairy because milk can potentially reflect environmental and production-related exposure. Identifying the sources of these compounds is therefore important for understanding how they move through the farm-to-milk pathway.
Farm and Dairy Equipment Under Focus
Rubber is widely used across agricultural operations, including hoses, seals, conveyor components, tyres and other equipment. Contact with such materials provides potential pathways through which rubber-associated chemicals could enter agricultural environments or food-production systems.
The research does not mean that all detected compounds necessarily originate directly from dairy-processing equipment. Determining the precise sources and exposure pathways requires further investigation.
Why This Matters for Dairy Safety
The findings underline the importance of contaminant surveillance beyond traditional microbiological and chemical testing. As analytical methods become more sensitive, dairy laboratories can identify previously overlooked substances and investigate their potential sources.
For dairy processors and farmers, the study reinforces the value of food-contact-material management, equipment hygiene, environmental monitoring and traceability as part of a broader dairy safety strategy.
The research also highlights an emerging challenge for the dairy industry: maintaining milk safety requires monitoring not only the final product, but also the materials and environments that come into contact with milk throughout the supply chain.
