McDonald’s are willing to pay a premium amount just to recall the cadmium-tainted Shrek glasses. 

McDonald’s had been selling the glasses for $1.99 with a food purchase and $2.49 without food. The company will pay customers $3 for every glass they return. About million of glasses painted with characters from the movie “Shrek Forever After” are to be recalled. Shrek drinking glasses found to contain elevated levels of cadmium, which is hazardous for the health.

What is Cadmium?

Cadmium is used in some paints to make bright colors, but industry representatives said that it was unusual for paints containing cadmium to be used in consumer products like glassware.

Long-term exposure to cadmium has been associated with a variety of health problems, including kidney and bone ailments.

As of today, no injuries have been reported. The glasses, manufactured in the U.S. by ARC International, came in four designs to promote “Shrek Forever After”.

McDonald’s also said today that sales at U.S. restaurants open at least 13 months climbed 3.4 percent in May, fueled in part by the popularity of the “Shrek” promotions, McDonald’s said in a statement.

McDonald’s rose $1.63 to $68.38 at 4.00 p.m. in New York Stock Exchange composite trading. The shares have climbed 9.5 percent this year.
