Abstract
With the global increase in feline and canine ownership, there has been a corresponding rise in the use of antiparasitic drugs for companion animals to treat fleas (Ctenocephalides felis), ticks (Ixodes ricinus, Dermacentor reticulatus, and D. variabilis), sarcoptic mange (Sarcoptes scabiei var. canis), ear mites (Otodectes cynotis), and poultry red mite (Dermanyssus gallinae), with the goal of combating potential zoonotic diseases. While similar drugs are being banned or restricted in agriculture—fipronil being banned and imidacloprid being restricted due to concerns regarding their impact on non-target invertebrates—there is limited research on the environmental consequences of companion animal antiparasitic treatments, especially in densely populated urban areas worldwide. A systematic literature review was conducted to investigate the environmental transfer of fluralaner, a widely used isooxazoline insecticide and acaricide, and its potential impact on non-target invertebrates. Through a comprehensive analysis of published studies, this review concludes that fluralaner exhibits high toxicity to 28 insect species across 12 orders. There are unsubstantiated claims of soil persistence and literature indicating that runoff—resulting from washing, walking in the rain, and swimming— by companion animals could pose a potential risk to aquatic environments and ecosystems, with the primary concern of potential transfer to the environment through excretion in animal faeces. This review highlights the need for further research on the environmental transfer of fluralaner and its impact on the environment with the goal of better inform veterinary health providers, given this drug extensive use in companion animal species.
