Salmonella has been detected in the world’s largest chocolate factory run by Barry Callebaut in Belgium, but the majority of the products affected remained on site.

The company announced the news Thursday, and a spokesman said production was shut down at the plant which makes liquid chocolate for 73 clients, CBS News reported.

“All products manufactured since the test have been blocked,” spokesman Korneel Warlop explained. “Barry Callebaut is currently contacting all customers who may have received contaminated products.”

Salmonella is described as an illness-causing bacteria, according to the Centers for Disease Control and Prevention’s (CDC) website, and the majority of people infected suffer diarrhea, fever, and stomach cramps.

“Symptoms usually begin six hours to six days after infection and last four to seven days. However, some people do not develop symptoms for several weeks after infection and others experience symptoms for several weeks,” the agency continued.

“Salmonella live in the intestines of people and animals,” the site reads. Humans can be infected in multiple ways such as eating contaminated food, drinking contaminated water, or by touching infected animals, their feces, or environment.

Per the CBS report, the company notified clients and requested they not ship products made with chocolate since Saturday at the plant in Wieze. Food safety officials have opened an investigation into the matter.

“The Wieze plant doesn’t make chocolates to be sold directly to consumers and the company says it has no reason to believe any contaminated goods made by clients have made it onto shop shelves,” the CBS article said.

In May, the J.M. Smucker company recalled almost 50 different Jif peanut butter products because of potential Salmonella contamination, Breitbart News reported:

The U.S. Food and Drug Administration (FDA) said in a press release that it is investigating a Salmonella Senftenberg infection outbreak in 12 states that the FDA says is “linked to certain Jif peanut butter products produced at the J.M. Smucker Company facility in Lexington, Kentucky.” The investigation is in partnership with the Centers for Disease Control and Prevention  (CDC) and local and state authorities.

Barry Callebaut provides cocoa and chocolate products to companies such as Hershey and Nestle, according to the CBS article.
