Austrian and German health authorities traced six listeria deaths to contaminated acid curd cheese made by Prolactal. Lidl pulled the cheeses off its shelves on 23 January when suspicions of a link were first aroused.
The supermarket chain has now reiterated its warning to avoid eating two suspect Reinhardshof-branded cheeses. Prolactal has said its management is “deeply shocked” by the listeria cases and has stopped production at its Hartberg site in Styria pending a full investigation.
