Abstract
Transport of infected birds is thought to play a key role in the spread of avian influenza (AI) on poultry farms during epizootic outbreaks. Ensuring efficient cleaning and disinfection (C&D) of equipment used for transport is needed to prevent the spread of AI. This study aimed to evaluate the efficacy against the AI virus of C&D protocols applied on trucks and crates used for the transport of ducks during the H5N8 AI outbreaks in France in 2017. In 3 abattoirs, 16 transport vehicles and their crates were sampled by swabbing to detect the influenza type A genome by real-time reverse-transcription polymerase chain reaction. Vehicles were tested before and after decontamination, which was carried out in accordance with the abattoirs' protocols. A total of 86 samples out of 299 collected before C&D were positive for AI (29%); 7 trucks out of 16 transported crates detected positive for AI. After C&D, the AI genome was detected in 56 samples out of 308 (18%). Ten trucks were loaded with a shipment of AI-positive crates. Eight vehicles were detected positive in the cabin, on the truck bed, and/or on the wheels. Despite reinforcement of C&D, the efficacy of decontamination was variable among slaughterhouses. The efficacy seemed to depend on the initial contamination load, C&D protocols, and how the protocol is implemented. Breaks in biosecurity measures led to frequent contamination of trucks after C&D. Observational studies during animal health crises are of interest to analyze practices in emergency conditions and to put forward measures aimed at increased preparedness.
