Around 300 pet owners have sued Streetsville, Ontario-based Menu Foods Income Fund in U.S. District Court since the contamination was discovered more than a year ago.
The company announced on April 1 that it was settling lawsuits with pet owners in the U.S. and Canada, but terms were not disclosed.
Details of the deal were due in U.S. District Court in Camden on Tuesday, but lawyers in the case asked for a 24-hour extension. A hearing on the settlement agreement is scheduled for May 30.
The pet food was discovered to contain wheat gluten imported from China that was contaminated with melamine, a chemical used to make plastics.
