A pet food company has denied a report it bought pet food from a company which it sold back to elderly people.

The story has reignited debate about the safety of pet food in the United States and abroad.

The Food and Drug Administration (FDA) said it is “looking into the allegations.”

A spokesperson for the Petco and PetSmart chains told ABC News that Petco’s stores do not sell pet food directly to the elderly, but only provide the products to consumers through the retailer’s website.

The spokesperson said Petco is currently working with regulators and has opened a new division to ensure that the product is safe for the customer.

The company told ABC that PetCo does not knowingly buy or sell pet foods that are contaminated with bacteria, mold or viruses.

Petco, the world’s largest pet food seller, said the story was false and said that PetSmart does not buy pet food to the same extent.

It said PetSmart sells pet food that it distributes to pet owners and does not send it back.

The spokeswoman said PetCo has been working with the FDA to ensure its pet food is safe and that it has been “working with our supply chain partners and the USDA to ensure these products are available for purchase at retail.”

Petco did not immediately respond to ABC News’ request for comment.

In the US, pet food manufacturers must test the food before it can be sold to the public.

The FDA requires the pet food industry to post the results of its testing on its website, and the FDA has a program that helps pet food companies find out what foods are most likely to cause food poisoning.

The Centers for Disease Control and Prevention says that pet food products can be dangerous for pets.

“In addition to the pet owner and the caregiver, pets may ingest pet food if they swallow, chew, or bite the contents, which could result in aspiration pneumonia or death,” the CDC said.

The USDA says that if you buy food from the company, you should not eat it and the food is likely to be unsafe for your pet.

The food industry said that it takes the safety and quality of the food very seriously.

“We are constantly assessing the products we purchase and the processes we use to ensure our food is free of contamination,” a Petco spokesperson said in a statement.

“Our food is certified by the American Academy of Pediatrics (AAP), the American Veterinary Medical Association (AVMA), and the Food and Drugs Administration (FDCA).”

The company added that its “safety protocols are followed to ensure pet food meets its nutritional and health objectives and is safe to use for our customers.”

In a statement, Petco said it had been cooperating with the USDA’s investigation.

“Petco’s policy is to make sure our products meet our customer’s nutritional and food safety needs,” the company said.

“It is important to note that Petcos products do not have any ingredients or ingredients from pet foods, nor are any of our pet food ingredients GMO, free of antibiotics, and made with organic ingredients.

Our goal is to provide safe food to our customers in a safe environment and Petco has a zero-tolerance policy on any contamination,” the spokesperson said. “

This is our first reported incident of a PetCo product that could potentially be dangerous to pets.

Our goal is to provide safe food to our customers in a safe environment and Petco has a zero-tolerance policy on any contamination,” the spokesperson said.

A Petco spokeswoman told ABC’s “Good Morning America” that the company does not believe the food could be dangerous.

“The product was tested by our quality assurance team, which determined it to be safe for our pet population,” the PetCo spokesperson said, adding that the PetSmart chain has a similar policy and the company was not aware of any cases of the product being contaminated with dangerous bacteria or viruses as a result of its sales.

“These are all things we have taken seriously, and we are taking action to ensure Petco products are safe to eat,” the spokeswoman said.

PetCo did not respond to a request for more information.

The Petco statement said that the food was tested for salmonella, which is a bacterial disease that can cause illness in humans.

The statement said Petcos food is not subject to recall or recall notification.
