Albuquerque Police Department spokeswoman Trish Hoffman said Thursday an investigation is continuing but the man faces a potential charge for battery.
Hoffman says Food and Drug Administration authorities are also looking into the case and might pursue a federal felony charge for food tampering.
Police responded to the Sunflower Market in northwest Albuquerque on Jan. 26 after a woman called 911 and reported a store employee had given her what she was told was a yogurt sample. The woman told police she believed it was actually a bodily fluid.
Hoffman says the man was arrested on an unrelated warrant.
