The Environmental Protection Ministry opened a criminal investigation this weekend against alleged abuse occurring in Tnuva's Beit Shean slaughterhouse, the ministry said on Saturday evening.

In conjunction with the Beit Shean police, an Environment Ministry team launched the investigation on Friday following an undercover exposé on the company's Adom-Adom brand slaughterhouse that aired Thursday night on Reshet TV's Kolbotek program.

The ministry credited Kolbotek for uncovering "grave findings" on the program, which included video evidence of workers electrifying calves by means of a shocker, as well as beating them, standing on them and dragging them by their legs using a forklift.

"There is no reason that animals should experience such horrible abuse over the course of their lives," said Environmental Protection Minister Gilad Erdan.
