You're over-reacting. These reports come out every year. Salmonella is everywhere.
Honestly, some store bought eggs contain it. Ever see the disclaimer on menus in restaurants about under-cooked eggs and meat? This is why. At one time they tried to legislate no dippy eggs be served because of it.
Wash hands, cook meat, go on with your life. IF your new birds had it, I think it will spread, but it really isn't that big an issue. They could just as well get it from wild birds or the soul
Chalk it up as slow news day.
Just my opinion, but I surround myself with dirt to build a naturally strong immune system. I avoid sanitizers and stick with old fashioned soap and water.
Soap and water works for me...
Salmonella is all over the place, best defense is allowing your birds and yourselves to have a good immune system.
I bought birds from Mt Healthy last year (also a reported outbreak source) and this year... and haven't had a sick bird or person as a result....
