Not necessarily. CL is not difficult to clean up until it gets in the soil or on wooden surfaces. As for your neighbors goats, a double fence with about a foot or so between them will keep your goats from coming in direct contact with their goats. CL is not airborne unless the abscess is in the animals lungs. It is not passed through milk unless there is an abscess in the animals udder. Goats generally develop external abscess, not internal. In most cases, CL requires direct contact with broken skin to infect.I could rehome her to a non-breeding farm, but I feel now that any breeding animals I bring in will be exposed also, so I fear I will never be able to have a goat in milk for our family's use. My neighbor's goats are CL positive now as well, and they share a fence line.
