Some paper and bamboo straws contain so-called "forever chemicals" that could make them a less-than-ideal alternative to plastic, researchers have found.
Scientists in Belgium recently tested dozens of straws from supermarkets, retail stores and fast-food restaurants in the country, and found that the majority contained PFAS — a family of synthetic chemicals used in the manufacture of consumer products because they can resist stains, grease and water.
The researchers sampled 39 brands of straws made of paper, bamboo, glass, stainless steel and plastic. Of those, 27 were found to contain PFAS, though the concentrations were low.
The results were published Thursday in the journal Food Additives and Contaminants.

PFAS, an acronym for per- and polyfluoroalkyl substances, are often referred to as “forever chemicals” because they linger almost permanently in air, water and soil. They are frequently detected in food wrappers, cosmetics, carpet, furniture and textiles such as raincoats or workout clothes.
