What quality costs will Mars incur from its recall of Snickers candy bars?

The US chocolate maker Mars, one of the worlds largest privately-held companies, issued a voluntary recall in 55 countries for Snickers bars, Milky Way minis, and some other candy bar varieties that were manufactured in a Dutch factory between December 2015 and January 2016. A red piece of plastic was found in one Snickers bar by a customer in Germany; that piece of plastic was traced back to a protective cover used in the manufacturing process at a Mars production facility in the Netherlands. This recall potentially covers millions of candy bars; the recall does not affect Mars products made in the US. In an interview with the Financial Times, a financial analyst estimated that the recall would cost the company tens of millions of dollars.
