Here's a summary of research findings on microplastics in vegetables, fish, and meat:

* **Vegetables:** A study in *Environmental Pollution* found microplastic levels in fruit samples with a median of 223,000 particles/kg (IQR: 52,600-307,750) and in vegetable samples with a median of 97,800 particles/kg (IQR: 72,175-130,500). Apples were the most contaminated fruit samples. Source: [https://www.sciencedirect.com/science/article/pii/S0013935120305703](https://www.sciencedirect.com/science/article/pii/S0013935120305703)

* **Fish:** Microplastics have been observed in fish intended for human consumption, with typically one or two microplastic particles detected per fish.

* **Meat:** A study found XPS microplastics (MP-XPS) contaminate packaged meat at levels ranging from 4.0 to 18.7 MP-XPS/kg. Source: [https://www.sciencedirect.com/science/article/pii/S2214289419306738](https://www.sciencedirect.com/science/article/pii/S2214289419306738)
