Do you think the authorities might just have lifted the earlier restrictions too early? Looks to be the same strain from the government research centre at Pirbright as well!
I don't like seeing dead cattle piled up in a cart knowing that they have been culled early in their lives due to someone else's mistake.
I don't know much about foot and mouth but I do know there is a vaccine. Why don't they use it? Is it too expensive or does it have some sort of detrimental effect on the animals? What would be the effect if there was a national vaccination programme?

We can kiss goodbye to our export market for good if they use the vaccine, the Europeans wont take vaccinated meat. Not that our export market is worth **** all these days anyway.
as said the export ban is twice as long if we vaccinate plus once they have the antibodies you cannot test to make sure they aren't carrying it. Its a measure that if used here all the cattle vaccinated would be culled later on. The only reason to use it is if they can't shoot the cows fast enough. This is when they start having to cull everything within a certain radius of each outbreak. Lessons learned on the last 3 outbreaks are cull as fast as you can and hope.
From what i have been told foot and mouth can live for up to 90days in water, so it's a bit tricky to keep cattle away when the stuff is heading downstream.

Not strictly true, you can test for the non structural viral proteins that will be present in infected cattle, but not vaccinated ones. However, vaccination is only about 85% efficient so you are controlling rather than eradicating the disease. It may also cause an asymptomatic carrier state in a small number of animals. Overseas markets would then consider us an endemic disease area and would ban all our imports of animals, meats, dairy products, leather and (don't laugh, its a productive market) bull semen.
The new cases of FMD look like they are a continuation of the previous outbreak rather than a second laboratory escape.
