by “Microplastic contamination has been reported in beef and pork for the first time, as well as in the blood of cows and pigs on farms.
Scientists at the Vrije Universiteit Amsterdam (VUA) in the Netherlands found the particles in three-quarters of meat and milk products tested and every blood sample in their pilot study.
They were also found in every sample of animal pellet feed tested, indicating a potentially important route of contamination. The food products were packaged in plastic, which is another possible route.”

Plastic particles were detected in 18 of 25 milk samples of all types. PP and Styr-P were not detected
in any off the milk samples. PET in only 1 of the 25 samples (0.90 μg/g), PE in 2 samples (21 and
22 μg/g), PVC-P (6.1-13 μg/g) in 16% of the samples, and PMMA (0.11-1.2 μg/g) in 68% of the milk
samples. Although some of the milk samples do contain one or more plastics types, a general
answer cannot be given on how much plastic is present in Dutch cow’s milk
