» Hygiene lock : do you really manage to enter or leave a poultry barn/farm properly ? » Farm vs house hygiene lock » Reply To: Farm vs house hygiene lock
Rules for farm hygiene lock versus poultry barn hygiene lock may differ between countries and production types. Poultry barns should have their own hygiene lock, otherwise contamination between barns/flocks is favored, as well as contamination between the “working zone” (feed delivery, tractors, etc.) to the poultry barn. A central farm hygiene lock can be a supplementary tool to reduce contamination, when biosecurity need is increased, but may be less efficient for the drivers of vehicles which enter the farm, as they go back to the vehicle cabin afterwards. For all other pedestrians who parked outside the farm zone (employees, vets, advisors, etc.) it should improve the biosecurity.
In conclusion I think that both are complementary, and barn hygiene lock a minimal requirement
