Fish cured with salt and sea salt from India's east coast have a lot of tiny plastic bits in them—some types of plastic like PVC and polystyrene—and that could be a problem for our health and the environment.

What we've found so far is that salt-cured fish and sea salt from India's east coast may contain microplastics. The evidence we've reviewed leans toward the presence of tiny plastic particles in these products [1]. Our analysis of the available research shows that both salt-cured fish and sea salt from this region have been found to contain microplastics, including types like PVC and polystyrene [1]. These are synthetic materials commonly used in packaging and insulation, and their presence in food raises concerns. We don’t yet know how much of these materials people are consuming or what long-term effects they might have on health or the environment, but the fact that they are present is a signal worth noting [1]. We looked at one key assertion, and it was supported by eight separate lines of evidence, with no studies or data refuting it [1]. That means what we’ve seen so far points in one direction—microplastic contamination is detectable in these foods from this region. However, we don’t have enough information to say how widespread or severe the issue is, or whether it happens in other coastal areas too. Our current analysis is limited to what has been studied and reported so far. We can’t say for sure how much risk this poses, or whether certain processing methods make contamination more likely. More data would help us understand the full picture. Practical takeaway: If you're eating salt-cured fish or sea salt from India's east coast, it’s possible you’re also consuming tiny plastic particles. Until we know more, being aware of the source of your salt and seafood might be a reasonable step.
