State legislation providing for brucellosis eradication work on a complete area basis in Arizona was strengthened by passage of amendments to the law tightening restrictions on the disposition of reactors. All reactors are to be disposed of by July 14, 1959, and retention of reactors is not permitted in designated brucellosisfree areas. Written quarantine notices are used in area test work and dairy and beef cattle owners have been very cooperative.

It is anticipated that all counties with the exception of Maricopa will be certified by December 31, 1958.

At the present time, there is no State program for the establishment and maintenance of brucellosis-free swine herds.

The brucellosis eradication program in Arkansas has expanded to the limit of available funds. One deficiency in the program resulted from failure of the State Legislature at its last session to pass an auction barn law. However, the Legislature did enact two laws which are proving beneficial to the program; one inaugurating Statewide compulsory calfhood vaccination and the other providing for complete area work.

Local brucellosis committees have been very helpful in sponsoring meetings for the purpose of publicizing the program. They have also taken an active part in obtaining signatures on petitions requesting area testing.

Technicians are being used extensively in the Arkansas program. Carefully selected, well-trained and properly-supervised lay personnel have proved entirely satisfactory in carrying out many of brucellosis project operations.

The anticipated goals for calendar year 1958 are: (a) 25 counties to be initially certified; (b) area work will be in progress in 36 counties; (c) 31 counties will be qualified as certified.

The Statewide certification goal is 1960, which does not represent any change.

There is no program or provision for the establishment and maintenance of brucellosis-free swine herds in Arkansas.

The brucellosis program was accelerated considerably since September 1957, when the State laws in California providing for brucellosis eradication work on an area basis became effective. A total of 21 counties have been declared in the process of certification and one county has qualified as the initial certified area. It is anticipated that 38 counties will be operating on an area basis as of December 31, 1958, and that 10 counties will have been certified by that time. It is expected that the entire State will be certified by June 30, 1960 provided sufficient funds are made available.

The State brucellosis regulations were amended to terminate adult vaccination as of January 1, 1957 and to withdraw privileges as official vaccinates for such animals as of July 1, 1958. BRT trailer laboratories continue to play an important part in the brucellosis eradication program.

More personnel are needed to supervise properly the brucellosis eradication program in California. The practice of vaccinating dairy calves when they are over eight months of age also is a problem in California which continues to cause difficulties.

Provisions are available in California for the establishment and maintenance of brucellosis-free swine herds. As of December 31, 1957, there were 14 certified brucellosis-free swine herds in the State.

New Colorado regulations became effective in April 1957 which provide for the conduct of brucellosis eradication on area basis in conformity with the Uniform Methods and Rules. County brucellosis committees continue to be active in circulating petitions, calling meetings, and otherwise promoting the program.

It is expected that 30 counties will be certified by December 31, 1958, and that area work will be in progress in a total of 46 counties, provided funds are made available. The goal for State-wide certification is June 30, 1960.

No provisions are available in Colorado for the establishment and maintenance of brucellosis-free swine herds.

A revision of Connecticut's brucellosis law became effective April 1, 1957. This provides for indemnity payments on reactors, slaughter of all reactors, quarantine of infected herds, and incorporates the ring test into the official program. As a result, Connecticut qualified as a certified State on July 26, 1957, ten months prior to the goal previously established. Local brucellosis committees were effective in stimulating enthusiasm for the drive toward Statewide certification. Efforts are being directed toward a further reduction in the incidence of brucellosis by increased efforts to locate and remove remaining infection foci.

There are no general provisions in this State for the certification of brucellosis-free swine herds. However, there is a section in the State law that requires blood testing of all swine herds maintained on the same premises with dairy cattle. This section reads as follows: "After April 1, 1957, no swine or goats used for breeding purposes shall be kept on the same premises as cattle unless such swine or goats are certified free from brucellosis. Any positive reactors shall be immediately slaughtered and the premises cleaned and disinfected."
