10 Aug 2020 --- A new report has warned that nearly half of all take-out food packaging tested across major US food chains contains potentially toxic chemicals. The Mind the Store campaign and Toxic-Free Future nonprofit combined forces to investigate the presence of PFAS (per- and polyfluoroalkyl substances) – chemicals known to threaten human health – in Burger King, McDonald’s, and Wendy’s as well as top health-minded food chains Cava, Freshii, and Sweetgreen. The investigation showed that all six food chains sampled had one or more food packaging items that “likely contain” toxic PFAS.
