Sentence 1: Last month, Menu Foods recalled all of its 60 million products of dry and wet dog and cat food after pets began to fall ill and in some cases died of kidney failure. "Natural Balance, Pacoima, CA, is issuing a voluntary nationwide recall for all of its Venison dog products and the dry Venison cat food only, regardless of date codes. The recalled products include Venison and Brown Rice canned and bagged dog foods, Venison and Brown Rice dog treats, and Venison and Green Pea dry cat food. Recent laboratory results show that the products contain melamine. We believe the source of the melamine is a rice protein concentrate. Natural Balance has confirmed this morning that some production batches of these products may contain melamine," said a press released issued by Natural Balance.
