Microplastics contamination in selected staple consumer food products.

Unlabelled: The use of plastics in the manufacturing of food products is of concern as microplastics (MPs, 1 µm to 5 mm) find their way into food which poses risks to human health. This study is the first to report detection of MPs in selected staple food products in the Philippines, specifically sea salt, white and brown sugar, fish sauce, and rice. Raman microspectroscopy was used to identify the MPs and pigment additives.
