The Southern Nevada Health District will take a closer look at a popular brand of poker chips because of concerns about lead.

An Arizona news station hired a private lab to test Paulson brand poker chips for lead. All of them exceeded legal limits. Half of them were 160 times the federal limit.

The Health District says under normal use, the chips are not an immediate threat. But if your kids get a hold of them that could be a major problem. If they were to place the chips in the mouth, they most certainly have potential to sustain significant dose of lead.

The company that makes the chips is based here in Las Vegas and released a statement that says the chips are not a health hazard when used normally.

MGM Mirage is the only company that confirmed it's used the chips for decades. A spokesperson referred to a statement from the American Gaming Association, saying it's concerned and wants health leaders to look into the potential risks.
