Multiple PFAS analytes analyzed using LC-MS/MS. All tested PFAS analytes were below the limit of quantification (LOQ).

All tested PFAS < LOQ

PFOA — < LOQ

PFOS — < LOQ

PFHxS — < LOQ

PFNA — < LOQ

PFBS — < LOQ

PFHxA — < LOQ

Glyphosate	Not detected (Below LOQ)
AMPA	Not detected (Below LOQ)

Method: LC-MS/MS. Serving size: 28 g.

LOQ definition: LOQ = Lowest level the method can accurately quantify. "< LOQ" means the compound was present below the measurable threshold or not detected.
