US trade in livestock and animal products is valued in the billions. The US must maintain strict biosecurity not only to try to prevent the introduction or spread of disease, but also to keep the trust of our trading partners. If the US allows possibly infected animals in, then foreign countries will start banning US livestock and products which would result in the loss of billions of dollars. The unfortunate fact is that tens of thousands of dollars is minimal in comparison. Even in the horse industry alone which represents a small part of that trade, it isn’t worth risking our ability to export US horses.
I think everyone would agree that the US should be using the most accurate test possible but unfortunately the USDA is pretty tightly bound by the current regulations.
A couple of posters have mentioned how complicated it generally is to change regulations. While it doesn’t usually quite literally take an act of Congress, rewriting regulations is hard, expensive, and time consuming.
General overview - some laws/regs might be handled slightly differently but this is generally how it’s done:
Congress enacts the basic statute/law (US Code) then the regulatory agencies write the rules and regulations to enforce the statute.
”‹
”‹”‹”‹The regulatory agency writes the regulation, performs economic/environmental analysis as required, has it internally reviewed and revised to make sure it is legal, then posts it in the Federal Register for public review and holds hearings if necessary, revises it if necessary, then publishes the final rule again in the Federal Register(Code of Federal Regulations).
”‹”‹”‹”‹”‹This is expensive and time consuming so the agencies have to prioritize. Given the horse industry’s relatively low trade value compared to other agricultural commodities, changing the regulations in regards to horses is probably low on USDA’s priority list.
(Congress can change regs and agencies can issue emergency rules but neither of those things are common.)
I agree that requesting the USDA to make an exception is probably (almost definitely) futile. And counterproductive, IMO.
Contacting congresspeople is probably also futile but it has worked on rare occasion before so worth a try, I think.
