'Nuclear' candy turns out to be toxic

US authorities issued a recall Friday for a brand of Pakistan-made candy called Toxic Waste Nuclear Sludge Chew Bars because it turns out the sweets actually are toxic.

Tests showed that the cherry flavoring in the chew bars contained extremely high levels of lead - 0.24 parts per million when the US limit is 0.1.

"That potentially could cause health problems, particularly for infants, small children, and pregnant women," the Food and Drug Administration said.

The recall affects all flavors of the candy and all the bars the company ever made from its inception in 2007 until January 2011.

The candy was imported from Pakistan by an Indiana-based company called Circle City Marketing and Distributing, which said it has not received any reports of sickness from the product.
