A Marion County grocery store deli worker was arrested Wednesday after authorities say at least two of her co-workers ate bean dip she spiked with methamphetamine, leading to one of them being hospitalized.

The Marion County Sheriff’s Office said Thursday that investigators had “no reason to believe” any customers of the Jefferson Thriftway on Old Pacific Highway were served any of the meth-based bean dip.

Cassandra Medina-Hernandez, 38, of Albany was arrested Wednesday. She remained held Thursday in the Marion County Jail on suspicion of delivery of methamphetamine and causing another person to ingest a controlled substance.

According to a probable cause affidavit, surveillance footage from the deli at the Jefferson-based store on Sept. 9 showed Medina-Hernandez remove something from inside her bra while her back was to the camera, go behind a microwave, lean down and wipe her nose when she stood up. She then walked to a table, got a small paper dish, turned her back again to the camera, and placed bean dip in the dish. The affidavit said the item she retrieved from her bra also appeared to be on the plate.

Medina-Hernandez allowed two store employees to eat from the dish and Medina-Hernandez also ate some of the dip, the affidavit said.

An assistant store manager contacted the Marion County Sheriff’s Office later that night and reported her daughter was hospitalized for unknowingly being given food with meth in it while at work, the court documents said.

The manager said she was told by another employee that Medina-Hernandez and the third worker who ate the dip intentionally put meth in her daughter’s food.

The daughter told the deputy that she went to the deli to get something for lunch, saw Medina-Hernandez making bean dip and asked to try some, the affidavit said. She took some of the dip home with her about a half-hour later, “thought one of the bites she ate tasted odd, but she did not think anything of it,” the affidavit said.

She returned to work and felt her stomach was upset and her feet were unsteady. She said she’d never taken meth before, the affidavit said.

The employee who spoke to the assistant manager told the deputy that Medina-Hernandez told her she put meth in the sick worker’s food, the affidavit said.

The third employee who ate the bean dip told the deputy that Medina-Hernandez texted her explaining the meth in the sick worker’s food was an accident, the affidavit said. The employee said she didn’t want to get Medina-Hernandez in trouble and said she was told the meth-laced dip was meant for Medina-Hernandez and another employee, according to the court papers.

Medina-Hernandez told the deputy that she didn’t want to speak without an attorney and agreed to turn herself in to authorities in Linn County, where she lives, the affidavit said.

The sheriff’s office said it doesn’t anticipate any other arrests being made in the case.
