A British waste disposal firm has been stripped of its hospital contracts after allowing medical waste to build up, including human body parts, the government said on Tuesday.Healthcare Environment Services (HES) lost contracts with 15 regional bodies within the state-run National Health Service (NHS), health minister Stephen Barclay said."While the waste was stored securely, it was not being processed and disposed of within the correct regulatory timescales," he said in a written statement to parliament. Opposition Labour lawmaker Jonathan Ashworth said the backlog involved "350 tonnes of waste, including human body parts, amputated limbs, infectious fluid".He told MPs it was "left effectively stockpiled" and was "an absolute scandal".Barclay insisted "that just 1.1 percent of this clinical waste is anatomical", adding: "At no point has there been an impact on public health."HES managing director Garry Pettigrew said most of the backlog was plastic and denied any "stockpiling" of body parts."All anatomical waste is disposed of safely and there are no body parts 'stockpiled' at any of our sites, as some reports have alleged," he said.He added that there was a lack of incineration capacity in Britain and the "excessive" decision to terminate its contracts would only make this worse.
