Did you seperate him after lancing it? If not, I would...and vaccinate those does. If he were here, he'd be quarantined until I could get him sold...which would be ASAP.
CL can live in the soil for a long, long time, especially in the housing areas where it's not exposed to the weather. We're talking years. If I'm not mistaken, I'm pretty sure I read (in The Goatkeeper's Veterinary Book, 4th Ed.) that open ground which has been fallowed for two years after containing goats can pretty much be considered "clean" for a new herd.
