Any program only lasts as long as funding for it exists. It seems easy enough to design the program so that it has a defined start and end goal and target end date. The Yellowstone herd in the US is a special case. According to USDA numbers released this month, the US is free of cattle and swine brucellosis in all 50 states. The program has been successful in eradication with the exception of an occasional case in the Yellowstone area. Work is in progress to ensure containment of cases which mainly seem to affect the elk in the park but also affect bison.

Since the program to eradicate began in 1954, brucellosis in domestic cattle and swine has been eradicated in all 50 states as noted by the USDA. Spending has ramped down accordingly to the point where less than $1 million dollars was needed in 2010.

There are active monitoring efforts in place since cattle are routinely trucked across country to pasture on better grass and since cattle do come across the border from Mexico, which still has a problem with control in some areas. With that in mind, it took the years from 1954 to 2010 for it to be officially eliminated.
