WINDOM, MINN. — Three US subsidiaries of Canadian pork processor HyLife Ltd. filed for Chapter 11 bankruptcy on April 27.

HyLife Foods Windom LLC, Tritek International Inc. and Canwin Farms LLC petitioned for relief in the US Bankruptcy Court for the District of Delaware. They estimated 200-999 creditors are owed. The companies’ liabilities and assets were both estimated to be in the $100-500 million range.

Two weeks ago, HyLife announced intentions to sell its Windom plant.

HyLife president and chief executive officer Grant Lazaruk cited unprecedented challenges like inflation, high grain costs and exchange rates as hurdles to the business.

“This is an extremely hard week, and we are unquestionably sad,” he said at the time of the announcement. “We are doing our best to share the information we currently have.”
