HOG CHOLERA 



There were no cases of Hog Cholera in the entire country during 

 this past fiscal year, a fact for which the U.S. Department of 

 Agriculture also deserves great credit. Potentially explosive, this 

 disease lurks in other countries and only the strictest of border 

 controls excludes it from our own large hog industry. Mandatory cooking 

 of all meat wastes and meat products that are fed to hogs is an 

 important facet of the constant battle against this disease. The 

 temptation for producers to use illegal but relatively easily prepared 

 vaccines against hog cholera also exists as a severe threat. 



SWINE BRUCELLOSIS 



The voluntary program to eliminate Brucellosis in the swine 

 breeding herds in Massachusetts continues. Less than fifteen herds 

 containing titered animals are now listed with the U.S. Department 

 of Agriculture and some of these are very close to validation. 

 Proposed legislation which would have made testing mandatory and 

 offered an indemnity program as an incentive to achieving IOO96 herd 

 validation in the state did not receive legislation approval but will 

 be resubmitted for further consideration. With several states to our 

 north now completely validated, it is important that we achieve the 

 same status. As with Bovine Brucellosis, this disease has a human 

 health impact and must be eradicated. 



PSEUDORABIES IN SWINE 



Although Pseudorabies in swine is prevalent in many other areas 

 of the country, it has not yet appeared in the breeding herds in 

 Massachusetts. Many of these are certified free of this disease and 

 export to other areas. Consideration is being given to legislative 

 controls with regard to imported animals. 



AFRICAN SWINE FEVER 



African Swine Fever exists in several areas of the Caribbean and 

 poses a real threat to the pork producers of the United States. This 

 disease is difficult to diagnose and has proven extremely difficult 

 to deal with once it gains a foothold in a country. It is vitally 

 important that it not enter the United States. Strict enforcement of 

 our garbage-cooking law with regard to meat wastes is believed to be 

 a strong deterrent to the entry of African Swince Fever as well as to 

 the reentry of Hog Cholera.
