Chocolate giant Mars Tuesday ordered a massive recall of Mars and Snickers bars as well as Milky Way Minis in Germany and the Netherlands after plastic was found in a product.

"Mars Chocolate is carrying out a voluntary recall of chocolate products of Mars, Snickers, Milky Way and Celebrations after a bit of plastic was found in a product," the company said in a statement on the recall in Germany.

Products with a best before date from June 19, 2016 to January 8, 2017 have been affected, it said.

The company said a full list of affected products could be found on its website www.mars.de but the site appeared to be down in the early afternoon.

"With this recall, we would like to prevent consumers who have purchased one of the above-mentioned products from consuming it," said Mars.

The US giant's Dutch subsidiary also issued a call-back for similar products with the same expiration dates, Dutch news agency ANP said.

The products covered by the Dutch recall were all made at a factory in Veghel, in southern Netherlands, ANP said.
