Police in eastern Austria have arrested a 39-year-old suspect following the discovery of rat poison in some HiPP baby food jars on supermarket shelves in central Europe.

The Burgenland State Criminal Police Office, under the direction of prosecutors, initiated an investigation after poison was found in a baby food jar purchased at a supermarket in Eisenstadt on April 18.

The suspect is currently being questioned, and further details have not been disclosed.

HiPP, the manufacturer of the affected baby food jars, expressed relief upon learning of the arrest and stated that it would provide additional updates as more information becomes available.

The company had previously recalled some of its baby food jars in Austria, Slovakia, and the Czech Republic after the case came to light last month.

HiPP emphasized that the recall was a precautionary measure and not due to any product or quality defect.

Authorities believe that the tampering occurred in 190-gram (6.7-ounce) jars of baby food made with carrots and potatoes intended for five-month-olds that were sold at SPAR supermarkets in Austria.

In response, HiPP recalled all its baby food jars from these stores as a precautionary measure.

Vendors in Slovakia and the Czech Republic also removed all of the brand's baby jars from sale.

The Austrian Press Agency reported that an expert report on the toxicity of the poison was pending.

A total of five tampered baby food jars were seized before they could be consumed, according to APA.

The Burgenland public prosecutor’s office has announced an investigation into suspected 'intentional endangerment of the public.'

No one had consumed the affected baby food by the time of the discovery.
