In one of the largest product recalls in history, US food giant Cargill has recalled more than 36 million pounds of fresh and frozen ground turkey because of a possible salmonella contamination.
One man has been killed by the strain of salmonella, and 79 others have taken ill.
Food advocates in the US are calling for changes to mean recall rules after it took regulators months to warn the public about the salmonella threat.
A government agency that tracks antibiotic-resistant pathogens found evidence of the contamination in Cargill ground turkey in early March, but it took five months for the recall to be announced.
On Friday the company admitted that Salmonella Heidelberg was detected at the Springdale plant even earlier than the March discovery.
