Chocolate maker Mars has recalled Mars and Snickers bars in Germany after bits of plastic were found in a product.
Other products affected include Milky Way Minis and Miniatures and certain kinds of boxes of Celebrations.
The products involved have best before dates from 19 June 2016 to 8 January 2017.
The US company has not said how many bars are affected, but its German unit produces around 10 million snacks every day.
A spokesman was unable to say if Tuesday’s recall was the biggest ever in the company’s history.
A full list of products affected can be found on the company’s website, www.mars.de, but that address appeared not to be responding on Tuesday afternoon.
The company said in a statement: “With this recall, we would like to prevent consumers who have purchased one of the above-mentioned products from consuming it.”
