Shelby Poole, the owner of Jackson's Restaurant in Commack, New York, uses regular paper in her cash register. She believes it's safer than the more common thermal imaging receipts used by many businesses.
Thermal paper contains the chemical bisphenol-A, also known as BPA. The chemical is already banned from baby bottles and sippy cups.
Suffolk County Executive Steve Bellone signed into law the Safer Sales Slip Act, which bans businesses from using thermal paper receipts.
Legislator Steve Stern sponsored the bill because he believes BPA is absorbed through the skin and can cause diseases and disorders.
But not everyone is convinced that BPA is dangerous. The American Council on Science and Health said numerous studies have never shown that BPA is a threat to health.
Businesses won't be fined until 2014.
The county executive said officials will use this year to educate businesses and give them a chance to switch over to the new system.
