Bait samples were solvent extracted and ergocalciferol concentration determined by high pressure liquid chromatography (HPLC). Ergocalciferol levels were constant for more than 21 days in dry samples and did not fall by more than 30% in 100 days. When water (10% w\/w) was added to the baits in the laboratory the ergocalciferol concentration fell by approximately 30 % in 30 days. In these wet laboratory samples there was a rapid visible growth of fungus and in normal rodent control use baits should have been replaced when such deterioration became evident.<\/jats:p>","DOI":"10.1017\/s0022172400028928","type":"journal-article","created":{"date-parts":[[2009,5,15]],"date-time":"2009-05-15T05:37:41Z","timestamp":1242365861000},"page":"253-258","update-policy":"http:\/\/dx.doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":1,"title":["The stability of ergocalciferol in rodenticidal baits"],"prefix":"10.1017","volume":"90","author":[{"given":"A.
