Maine has enjoyed a Modified Certified Brucellosis-free status since July 1950, and was the third State to reach this goal.
There are no significant deficiencies apparent in the program as now constituted. Increased activities are being directed toward locating and removing all remaining sources of infection. The ring test is routinely applied to all dairy herds on a semi-annual basis with prompt follow-up blood tests of suspicious herds. All herds not covered by the ring test are blood tested at least once in three years. Attention is being given to tracing sources of infection when reactors are found.
Interest on the part of cattle owners in the vaccination of calves has been stimulated as a result of certain importing States accepting only vaccinated animals.
Provisions are not available in Maine for the establishment and maintenance of brucellosis-free swine herds.
Although progress is being made in the Maryland brucellosis eradication program, wider acceptance and use of the brucellosis ring-test would contribute to more rapid advancements. Also, the project has been retarded by a serious shortage of supervisory personnel. It is unfortunate that local brucellosis commitnot taking a
active part in promoting the Maryland program.
It is antic pated that 11 counties will be certified and complete area work underway in 12 ther counties by the end of calendar year 1958.
The goal for State-wide certification is still 1960.
While provisions for the establishment and maintenance of brucellosis free swine herds are available in Maryland, there seems to be very little interest in this program except for owners having a need for meeting sales requirements. There is reason to believe the certification of swine herds could be expanded if tests were conducted without expense to owners.
Improvements incorporated into the Massachusetts program during the calendar year included provisions the State's participation in the payment of brucellosis indemnities; plans to concentrate on area certification work, the discontinuance of routine herd certifications, and wider use of milk ring tests to locate suspicous Brucella infected herds.
County Brucellosis Committees were active during the year in obtaining legislation to increase State brucellosis funds for the payment of indemnities, and holding meetings to discuss progress reports covering the program.
Three of the fourteen counties in the State are certified brucellosis-free. It is anticipated that the remaining eleven counties will qualify by December 31, 1958. This represents a change from the previously reported goal of January 1, 1960.
There are no provisions for the certification of brucellosis-free swine herds.
June 30, 1958 remains the goal for state-wide certification of Michigan. Twenty-seven of the 83 counties in the State are still to be certified during the first six months of 1958. Legislation and funds are adequate to achieve this goal. No significant deficiencies are apparent in the Michigan program. Local brucellosis committees, the Extension Service, and the Livestock industry are contributing greatly toward successful promotion of the program.
The Michigan program is designed to achieve complete eradication as soon as possible after certification is complete. It is estimated that the state-wide infection rate on December 31, 1958 will be 3.7 percent herds and 0.5 percent cattle.
There is no program for the certification of swine herds at this time. However, such a program is under consideration. A survey is being made through testing of blood samples obtained at local slaughtering establishments to determine the extent of swine brucellosis in the State.
On May 31, 1957, Minnesota became the seventh State to attain state-wide certification. Those responsible for the program in Minnesota recognize the fact that attainment of this status is only an important milestone on the road toward complete eradication of bovine brucellosis. Increased efforts are being made to locate and remove residual foci of infection.
Although the program as presently designed is effective, considerable savings in funds and personnel could be made by a wider acceptance of the results of ring test operations.
During 1957 legislation was enacted which requires the prompt removal of reactors and their slaughter within 15 days after branding and appraisal.
Considerable credit must be given to the practicing veterinarians in Minnesota for bringing to a successful conclusion the initial stage of the eradication program, Through their continued cooperation final and complete eradication should be attainable,
It is estimated that the herd infection rate will be reduced to 1.9 percent and the cattle infection rate to 0.15 percent by December 31, 1958.
Provisions are available for certifying brucellosis-free swine herds. As of December 31, 1957, there was one such herd in Minnesota.
