    Are cash-register receipts hazardous?

    Bisphenol A (BPA), a compound used in making plastics, has been controversial for years because excessive accumulation in the body can have negative effects on health, especially for the foetus. Cash-register receipts contain BPA, which has been demonstrated to penetrate our skin.


    Supermarket cashiers have almost twice as much BPA in their blood as someone who does not spend the entire workday touching receipts. The reason for this is that BPA is in one of the layers of the “thermal paper” that is widely used in cash registers and credit card terminals. When we touch that layer, the compound penetrates our skin and enters the bloodstream. We all have BPA in our blood, but opinions about the potential hazards are conflicting.  Some countries have already scheduled a progressive ban on BPA. But the fact remains that, to date, no health authority has banned its use in industry other than in the manufacture of baby bottles.
