BLACKSBURG, Va. -- The company behind several brands of rawhide pet products has issued a voluntary recall over concerns that they may contain an industrial cleaning product.

United Pet Group, a division of Spectrum Brands, is recalling multiple brands of rawhide dog chew products that were sold to retail outlets and online in the United States.

The recall comes after the company found that facilities in Mexico, Columbia, and Brazil were using a "quaternary ammonium compound mixture" as a "processing aid" in the products' creation. That compound is an antimicrobial chemical that has been approved for cleaning equipment but not for processing the rawhide products themselves - at least not in the United States.

"We take our responsibility to pets and their owners seriously and we are continuing to investigate the cause of this problem," the company said in a statement. "We are implementing changes across the affected manufacturing facilities in order to prevent this problem from reoccurring in the future."

The company confirmed it has already received at least some reports of pet illness - though a limited number compared to the volume of the product in distribution. Those consumers who did have sick pets said they noticed an unpleasant odor. Some also reported that their dogs were vomiting and having diarrhea.

"Exposure to quaternary ammonium compounds through direct ingestion may cause the following symptoms in dogs: reduced appetite, and gastric irritation including diarrhea and vomiting," a company statement said. "These symptoms may require treatment by a veterinarian depending on severity."

The products all originate from the company's Edwardsville, Ill. distribution center but were distributed nationwide. They include:
