So my uncle was drilling through our ceiling to put some wiring in to install a light anyways, player and stuff went everywhere and I realised that his plaster has hair in it, researched it and apparently it is horse hair plaster which could contain anthrax so scared we been out at risk and also my toddler son managed to pick up some and our it in his mouth the bits I didn't notice and didn't clean and couldn't get the hair out In time before he swallowed it could he get ill I'm so so worried
