Mars believes an “isolated incident” in one of its factories in the Netherlands led to plastic being found in a Snickers bar bought in Germany.
The company has voluntarily recalled Snickers bars, along with Mars Bars, Milky Way and Celebrations products in at least 55 countries, including the UK, after the small piece of red plastic was found by a customer last month.
The recall concerns items produced between 5 December 2015 and 18 January 2016 at Mars’ Veghel site in the south of the Netherlands, which are labelled “Mars Netherlands”.
The Netherlands Food and Consumer Product Safety Authority said the plastic posed a choking risk.
The plastic is thought to have come from a protective cover used in the manufacturing process, according to the Guardian newspaper.
“While the number of Mars products affected is limited, they have been shipped to numerous countries outside the Netherlands, including some duty free retailers,” said Mars in a statement.
“As a precaution, the product recall is being implemented in all markets served by our Netherlands facility.”
Mars UK said: “Mars Chocolate UK regrets any inconvenience caused to our consumers. We offer our consumers our sincere apologies.”
