Don't know if there's anyone out there who knows a lot about biosecurity. I'm a student who lives away from home and works at the poultry farm at my school (once or twice a week, we are a smaller farm), but I also have my own small flock back at home. I only go home a few times a year. Basically my question is how much should I worry about bringing possible diseases between the two flocks. I have my own boots for work that will never be used at home, and I walk through disinfectant pans when entering the pens at work. Similarly, I have my own shoes at home for my coop that never go anywhere else. I was told by my boss that NPIP says 48 hours is the amount of time where it is safe to go from one flock to another, so I didn't know if anyone else could confirm that. There is always around a 5 day period between me working at the farm and going home to my birds. My main worry is that the birds at the farm get bumblefoot sometimes, and I really don't want my birds catching it. Any insight is appreciated.
