Police said some of the medicines were expired. On other bottles some of the expiration dates were tampered or obliterated. It appears all the medicines were purchased legally in Guatemala and other Central American countries.

Rosa Yaneth Aguilar Tzampop, 25, of Oakland, was arrested on suspicion of dispensing or furnishing medicine without a license and possessing hypodermic syringes. Both are misdemeanor charges, police said.

Police contacted Marin County Public Health Officer Jason Eberhart-Phillips, who advised, “Antibiotics purchased on the street are potentially very dangerous and should be never used…Using these medicines puts you at risk of serious illness, even death, because no one can vouch for their safety.”

The San Rafael Fire Department will accept any medicines sold on the street at any of their city firehouses and will dispose of them properly. Consumers are asked not to throw away medicines in the garbage or down toilets and drains, police said.

The California Poison Control System told police the antibiotics seized by police could be toxic to the kidneys if taken.
