The United States has recalled more than 1,200 dog food products, citing the possibility that they contain a carcinogen, the US Food and Drug Administration (FDA) said in a statement on Wednesday.
The US government said in March that it had recalled more 1,600 products after the agency received complaints of gastrointestinal illness from dogs.
It has also announced a recall of dog biscuits.
The products affected include dog food brands that are recalled from the United States, Canada, Mexico, Japan, Australia, New Zealand, China, South Korea and Taiwan.
The agency said in its statement that the dogs that received the product were in their first year of life and were in the care of the owners.
“The dogs that had received the recalled product had gastrointestinal illness,” it said.
“We are continuing to investigate the nature of the recalled products and the possible connection to this outbreak.
In the meantime, the FDA has decided to take immediate action to recall these products.”
In March, the United Nations launched an investigation into the contamination of dog food sold in the US, in response to the contamination by a Japanese manufacturer of a dog food with a suspected human carcinogen.
The United States recalled nearly 2 million dogs, mainly because of gastrointestinal issues, after a batch of dog meat in a package was found to contain aflatoxin, the agency said.
