That’s terrible luck
One of the things that worried me the most moving my lot south was moving from TB4 to a TB-endemic area.
We did hear of farms in the TB4 zone getting the occasional reactor, even when there’d been no movements at all and no neighbours with any. We surmised deer or badgers, but you can never be sure, of course. It had been found in badgers 30-odd miles south, but never that far north.
Do you have any other animals on the holding? Other ruminants, dogs, cats, anything? It’s unusual in other species but not unknown, so that might be another possible source.
We use AI to reduce the possibility of bringing infection on - easier with our Jersey and Jersey cross than with Dexters, but yours sound tame, so could be a possibility for the future.
Fingers crossed the other girl stays clear. You’d get her a companion if so? Very hard decision.
