Jeremy Clarkson
Clarkson's Farm viewers are eager to discover what transpired at Diddly Squat Farm following suspicions that one of Jeremy Clarkson's expectant cows had contracted TB (Bovine tuberculosis). Welsh vet Dilwyn Evans had been conducting routine examinations on Clarkson's herd when he identified a potential 'fail' on one of the animals, who was carrying calves. In distressing scenes during the final episode of Season 5, the very first cow to have been brought to the farm, while expecting twins, was sent to be put down after the suspected TB outbreak resulted in two inconclusive examinations.
Clarkson was subsequently left with his "blood boiling" after a post-mortem of the animal revealed she did not actually have TB, yet the farm was still obliged to remain in lockdown. Here is everything you need to know about the current situation at Diddly Squat following the TB scare.

The outbreak occurred in August of 2025, prior to Season 5 of Clarkson's Farm being released, with the former Top Gear host announcing it on X.
When a cow fails a TB test, the whole herd must be placed on lockdown and any affected animals are legally obliged to be slaughtered. Fortunately, Clarkson disclosed in a column for The Sun in March 2026 that the farm had emerged from lockdown restrictions.
He said: "After seven months of lockdown, Diddly Squat farm became officially TB-free this week."
Sadly, there was some unwelcome news to contend with, as he went on to reveal: "But before we had a chance to celebrate, we found out that one of our donkeys has laminitis and must be put down.
"In farming, it seems you are allowed one bit of good news, but it must always be accompanied by some kind of disaster."
The television personality had previously spoken candidly about the severe impact the TB lockdown had on the farm, which had been prevented from trading as a business.
He said in his column for The Times: "All the barns we needed to store the grain in, we now have to convert into a cow hospital.
"We've got another calf with pneumonia, so that needs to be housed. And we can't buy or sell a cow now because the farm officially, you know, has TB."
Following such a torrid period, Clarkson and his team can now look ahead with renewed optimism, with the threat of TB finally lifted from their shoulders.
