Israeli health officials and police are investigating a disturbing baby-food scare in Jerusalem after toddlers were hospitalized and later found to have traces of benzodiazepines, a class of sedative and anti-anxiety drugs used in adult medications such as Klonex and Valium.

According to Kan News, three toddlers from Jerusalem were taken to Hadassah Ein Kerem after showing symptoms including apathy and weakness. They were hospitalized for observation and later released. The Health Ministry has confirmed that it is investigating a possible link to fruit puree products made by the baby-food brand Prinok and purchased at Zol U’Begadol branches in Jerusalem.

At this stage, officials say they cannot determine whether the product caused the symptoms, and police are also involved as investigators examine all possible directions. The products reportedly were purchased as individual units, not as part of a multipack.

Benzodiazepines are not food additives, but rather they are powerful medications that can cause central nervous system depression, drowsiness, weakness and confusion, especially in young children. The symptoms described by the ministry are exactly the kind parents are now being told to watch for are unusual sleepiness, exhaustion, behavioral changes or confused speech.

The Health Ministry is urging parents who gave their children the suspected product to monitor them closely and contact their pediatrician if symptoms appear. Parents are also being asked to contact the ministry hotline at *5400 and report the child’s exposure to the product.
