Doganjo
Apologies for the typo ! However now that you have explained the derivation I should hopefully not get it wrong again. Am worried that the dog comes first then the lady and the bloke a poor third, but probably like our household it is very true
For England there are 8 notifiable diseases relevant for
pigs (not sure if the talk you went to was just pigs or all animals)
Under the 1981 health act
African Swine Fever
Aujeszky's disease
Anthrax
Classical Swine Fever
Swine Vesicular Disease
Teschen Disease
Vesicular Stomatitis
and Brucellosis under the Specified Diseases Orders 1992 and 1996
Of these, the only potential for sudden death would be Anthrax, and the last case of this was in 2006 in 2 cows in Wales. It does occur in pigs, but is not common. Typically pigs go off food for 24 hours before, and frequently have hot swellings in the throat.
From a little look at the 2006 Scotland Animal Health Bill which references the 1981 UK wide act, I would expect Scotalnd to have much the same rules.
As Lillian says any sudden unexplained death without any other factors should cause you concern and you should consult your vet, and it is them who would typically inform AH if they dignosed or suspetcted a notifiable disease.
I would doubt a statement from an AH rep that either all fallen stock or those suffering sudden death HAVE to be reported without some supporting regulations or law.
Again as Lillian says informing a police constable would be pointless and confusing to them, but AH was not around when the 1981 Act was written. As the Act is still on the statute books, and this is what it says, you would be compliant by telling the local PC !
