WASHINGTON (AP) _ Hartz Mountain Corp. has agreed to settle an Environmental Protection Agency complaint that it failed to report cases of pet illnesses and deaths from a powerful flea and tick repellent.

However, the Harrison, N.J.-based pet product giant admitted no liability, according to a statement.

The company agreed to pay $45,000 of the original $90,000 in fines, which stemmed from a 1987 investigation into complaints from veterinarians and consumers that Blockade sprays were making some dogs and cats sick.
