1

what would be known as a peracute condition of sudden death

suddenly found dead with no preceding signs

2

anthrax investigation - contact APHA if clinical signs are suggestive or no other cause can be identified
collect blood from marginal ear vein

3

6-24 months
sudden death, lameness and swelling of the proximal limb and emphysematoua and respiratory distress if the tongue swells
animals have a good body condition score

7
