Thai authorities have confirmed the existence of listeriosis-associated apples imported from the U.S. to Thailand, advising the public to thoroughly wash fruits and vegetables before consumption.

The Director-General of the Department of Medical Science (DMSC) Apichai Mongkol have addressed the warning issued from the U.S. Food and Drug Administration (FDA) about the recall of the apples from Bidart Bros. as the FDA have confirmed a contamination of Listeria in the apples.

Produce contaminated by Listeriosis have been confirmed in Thailand at the Laem Chabang port in Rayong province through a cargo vessel, as warned in the FDA’s document.

Two strains of Listeria monocytogenes were confirmed in the Bidart Bros apple processing plant near Bakersfield, California, the FDA said.

“Those same strains were also found in Bidart Bros. apples collected from a retailer,” the FDA said in a statement on Friday.
