STORY AT-A-GLANCE

• Conventionally grown and organic kale may be contaminated with toxic per- and polyfluoroalkyl chemicals (PFAS)
• Out of eight kale samples purchased in four U.S. states, only one had no detectable PFAS
• Among the others, the highest level of total PFAS was found in conventionally grown kale purchased in a Georgia Publix store
• Overall, PFAS levels were higher in organic kale samples than conventional samples
• Kale is just one example — albeit a surprising one — of where you may come into contact with PFAS; concerning levels of PFAS have also been found in peanut butter, pasta sauce, freshwater fish, cooking oil and many other consumer goods
