How long can Pasteurella live in soil?

[Mmueller12]

Hey everyone - I had 2 different sources for some younger chicks and I kept all of them separated when in the yard (they weren't combined with my older hens yet), but unfortunately, they either came with pasteurella or got it from somewhere. Now, I still have the area fenced off in my yard and it's been that way for about a month. I've read that it can live in the soil for months - does anyone know if that's true? I'd love to take the temp fence down.

Thank you,
Melissa
