First Priority, Inc. has recalled over 1.2 million syringes of canine and feline piperazine deworming pastes because the products failed stability testing. The deworming pastes were found to be too thick (high viscosity) to be used as intended, and the canine version also contained an improperly high concentration of the active ingredient (high assay). This recall includes several popular brands like Hartz Ultra Guard, Happy Jack, and Worm Protector sold in Alabama, Illinois, Missouri, New Jersey, North Carolina, Ohio, Puerto Rico, and Texas.
The thickened consistency may make it difficult to administer the correct dose, while the canine product's high potency could lead to accidental over-medication of pets. No specific pet injuries have been reported, but the products no longer meet safety and quality specifications for effective treatment.
