All farmers and vets were confounded,

The heifer in deep and strange distress,

Grass stagger symptoms, minerals in balance,

Blood tests tell no tales,

The cow moves distraught about,

Eyes with tears, walking with dropped withers,

And the animal cannot stand,

It always staggers to keep its feet,

When we saw, how could we foretell,

The vast numbers in pain with it,

And that variant CJD would befall,

It was me that got a future shock,

It would change me in later years,

In programming, tagging and tracing cattle all.
