Cargill Meat Solutions Corp. has announced for the second time in less than six weeks a voluntary recall of ground turkey products after tests found they were contaminated with a strain of salmonella bacteria that can prove fatal.

“That’s one of the challenges and frustrations about trying to get one’s arms around a naturally and randomly occurring bacterium that exists throughout the environment,” said Mike Martin, director of communications for the company in Wichita, Kansas.

“It is frustrating but it strengthens our resolve to also do more to find additional methods and measures that are going to further reduce the potential for pathogens that can cause food-borne illnesses.”
