Yes, Some TSCs in some places get some of the bird's from Mt Healthy. But, they also use Townline here in the upper midwest and other hatcheries other places. Since Mt Healthy had an outbreak a year or so ago and were deluged with Federal inspectors, it would very unfortunate if they were once again the source. Thanks for the news link outing Mt Healthy as the source of the outbreak, such news travels very, very fast.
I think in the Minnesota case reported, the story did not identify any hatchery as the source of the outbreak, but seemed to suggest that was from the ducks at that store. It wasn't entirely clear, but that seemed to be the take away.
Children, especially, are at risk when they handle or snuggle chicks or ducklings. Kids put their fingers in their noses, mouths and rub their eyes. This is reality of poultry handling. Wash your hands, of course. Here's to hoping it all works out well.
Thanks for bringing this issue forward. It is important.
