ALBUQUERQUE, N.M. (AP) — A cook at a New Mexico facility that trains state corrections employees faces battery charges after authorities say she secretly licked sandwiches then served them to probation and parole officers.

KOAT-TV reports (http://goo.gl/MCnk5i) Yolanda Arguello (ar-GWAY’-oh) was charged last week following witness interviews into the bizarre allegations at the South Valley New Mexico Women’s Recovery Academy in Albuquerque.

According to a criminal complaint, witnesses told investigators that the 59-year-old would take a piece of cheese, lick it and put it on sandwiches at the academy. Another witness told authorities Arguello was seen sucking on an ice cube and putting it back into a cup before handing it to a staff member.

She is charged with three counts of battery on a peace officer.

It was unknown if she had an attorney.
