An alternative hypothesis is proposed that cites exposure of the bovine embryo to various specific high-dose lipophilic formulations of organophosphates, such as the high-dose phthalimide containing organophosphate phosmet, (which were applied compulsorily and exclusively in the UK during the 1980s/early 1990s) as the primary trigger that initiated the deformation of prion protein and the onset of the bovine spongioform encephalopathy epidemic.

It has been suggested that exposure of cattle to the ectoparasiticide Phosmet in the 1980s caused a conformational change in the cellular prion protein (PrP (C)) to form the BSE prion (PrP (SC)), which initiated the epidemic of bovine spongiform encephalopathy (BSE).
