Pfizer plant prepped before demolition to contain killer API

A former Pfizer manufacturing site in the UK got a good cleaning before it was demolished. Plant decommissioning specialist EDS cleaned piping and process equipment in addition to sealing structures to prevent toxins from reaching a nearby river. Selamectin materials, the basis of Pfizer's pet anti-parasite treatment Revolution, were the chief toxin of concern. According to EDS, "a pin head of Selamectin released into the local watercourse could kill all marine life for 10 miles." Story
