Microplastics in the food chain: is milk immune from microplastics contamination?
A group of scientists from the Mexican Instituto Politécnico Nacional (IPN) collected and tested a total of 23 milk samples from five international and three national brands to detect the presence of microplastics.
Milk is often tested for the presence of contaminants like allergens and pathogens, however the repercussions of microplastics along the whole manufacturing chain (from the farm to the dairy industry) were largely unknown.
The study demonstrates that the levels of microplastics contamination in branded milk need to be taken into account as a direct effect of the industrial process. The results showed that the release of secondary microplastics is a significant source of plastic waste in branded milk.
The European Commission’s Rapid Alert System for Food and Feed’s portal and the European Food Safety Authority’s website reported the presence of microplastics contaminants in many food products.
WHAT TO DO?
The vast array of different plastic types available on today’s consumer market makes the qualitative or quantitative analysis of microplastics extremely challenging and there are currently no officially recognized methods available.
Thanks to the long standing experience of EcamRicert-ECSIN laboratories, it has been possible to develop and validate specific methods that can be applied to diverse matrix types including detergents, cosmetics, drinking water, milk, beverages, mineral salts, fish products and environmental matrices.
