A recent study has revealed that cheese and other dairy products may contain microplastics, raising concerns for food safety and public health. Researchers found that cheese carries significantly more microplastic particles than milk, with certain types being more prone to contamination.
Microplastics are tiny plastic fragments typically smaller than 5 millimetres that originate from plastic containers, water bottles, packaging, and other everyday items. These particles can infiltrate the food chain and have been detected in multiple human organs, including the liver, stomach, and even blood vessels.
The study, conducted by the University of Padua in Italy and published in the npj Food journal, analyzed 28 dairy samples including milk and various types of cheese. Microplastics were found in nearly all samples, except two. Milk contained around 350 particles per kilogram, while cheese had a staggering 1,000 particles per kilogram. Common plastic types identified were PET, polyethylene, and polypropylene, often linked to packaging, processing machinery, farm equipment, and animal feed.
Certain cheeses were found to carry higher microplastic loads. Fresh cheeses like mozzarella, ricotta, and paneer contained approximately 1,280 particles per kilogram, while aged cheeses such as cheddar, Gouda, and Parmesan had around 1,857 particles per kilogram, making them the most contaminated.
Exposure to microplastics may have serious health implications, including inflammation, hormone disruption, liver damage, gut disorders, and mental health effects. Long-term risks may include cancer, infertility, heart disease, and lung problems. Experts recommend staying informed about dairy product safety and maintaining a balanced diet while research continues.
