Iophenoxic acid derivatives as markers of oral baits to wildlife

Abstract: The bait-marker iophenoxic acid (IPA) and its derivatives are increasingly used for evaluating and optimizing the cost-effectiveness of baiting campaigns on wildlife, particularly on game species such as the wild boar. We aimed to determine whether concentrations of the three main IPA derivatives ethyl, methyl and propyl-IPA measured on thoracic liquid extracts (TLE) of hunted wild boars may be representative of two exposure doses, 40 and 200 mg, from 20 to 217 days after ingestion. Then we developed a method … Show more

“…During initial field trials, tetracycline was used ( Kaden et al, 2000 ). However, bait markers efficient in this species (i.e., tetracycline, iophenoxic acid, rhodamine) are supposed at risk for human health, since wild boar are hunted and consumed by people ( Ballesteros et al, 2013 ; Sage et al, 2013 ) and subsequently increase the overall cost of vaccination, which compromises the use of chemical markers at a large scale in natural populations ( EFSA, 2008 ; Anses, 2012 ). Beef tallow which was used in the original bait, was removed from the bait matrix because regulatory requirements limited the use of certain bait materials (e.g., products derived from terrestrial animals; tissues that may transmit spongiform encephalopathy).…”
