It is our firm iaelief that the manifestation of this disease, 

 discovered in Massachusetts in 1976, came from the use of hog cholera 

 vaccine. It is quite possible that the use of this vaccine continued 

 after it was outlawed in 1969. 



It is reliably reported that hog cholera vaccine still exists in 

 Massachusetts. It is likely that it will be used again. In view of 

 this situation, plans should be made to continue a surveillance of 

 Massachusetts hogs for the presence of hog cholers titero It is 

 recommended that every herd be checked at least once per yearc Much 

 of this could be accomplished by splitting samples taken in connection 

 with brucellosis eradication and revalidating. 



BRUCELLOSIS ERADICATION IN SWINE 



The number of known hog farms with brucellosis infection is now 

 less than a dozen. Some of those remaining are large. It is possible 

 that complete clean-up will require the implementation of a law making 

 eradication mandatoryc A bill will be placed in the legislative channels 

 calling for complete eradication and indemnity. Study may show that a 

 redesigning of import requirements may be in order to protect our farms 

 from reinfection o 



PSEUDORABIES IN SWINE 



The increased prevalence of Pseudorabies in other parts of the U»S. 

 is a signal for us to study procedures to prevent its entry into Massachu- 

 setts. Import requirements should be developed, surveillance within the 

 state established and a laboratory in the state designated to perform the ' 

 necessary testing procedures. Policy and rules for the use of Pseudorabies 

 vaccine in Massachusetts should be developed. 



AFRICAN SWINE FEVER 



This devastating foreign disease is traveling toward us at a rapid 

 speed and may arrive here or the Caribbean via Puerto Rico at any time. i 



Stronger enforcement of the Garbage Cooking Law is now needed 

 because of the threat of this disease^ The most likely way of entry 

 to the UcSc is by illegal import of pork products on the person of 

 visitors or citizens from countries where African Swine Fever exists. 

 A legal proceeding is now in the planning stages with the Attorney General's 

 Office against a swine raiser who refuses to cook garbage and obtain a 

 permit to feed garbage.
