At the end of When Birds Get Flu and Cows Go Mad!, author John DiConsiglio leaves what problem unresolved?

Whether, the U. S does more testing on cows.

Whether testing on cows should be continued by the United States

Explanation:

In the book When Birds Get Flu and Cows Go Mad! we have a great account of the animal health and disease problems that they can pass on to us, ranging from how cows caused problems in the pacific and even bird flu we eat every day, unfortunately at the end of the book John Diconsiglio doesn't make it clear whether cow testing should continue in the US for disease detection and to prevent the next pandemic disease.
