Brucellosis is a contagious disease affecting animals and humans, caused by bacteria of the genus Brucella.

The brucellosis regulations, contained in 9 CFR part 78 (referred to below as the regulations), provide a system for classifying States or portions of States according to the rate of Brucella infection present and the general effectiveness of a brucellosis control and eradication program. The classifications are Class Free, Class A, Class B, and Class C. States or areas that do not meet the minimum standards for Class C are required to be placed under Federal quarantine.

The brucellosis Class Free classification is based on a finding of no known brucellosis in cattle for the 12 months preceding classification as Class Free. The Class C classification is for States or areas with the highest rate of brucellosis. Class A and Class B fall between these two extremes. Restrictions on moving cattle interstate become less stringent as a State approaches or achieves Class Free status.

The standards for the different classifications of States or areas entail (1) maintaining a cattle herd infection rate not to exceed a stated level during 12 consecutive months; (2) tracing back to the farm of origin and successfully closing a stated percentage of all brucellosis reactor cases found in the course of Market Cattle Identification (MCI) testing; (3) maintaining a surveillance system that includes testing of dairy herds, participation of all recognized slaughtering establishments in the MCI program, identification and monitoring of herds at high risk of infection (including herds adjacent to infected herds and herds from which infected animals have been sold or received), and having an individual herd plan in effect within a stated number of days after the herd owner is notified of the finding of brucellosis in a herd he or she owns; and (4) maintaining minimum procedural standards for administering the program.

Before the effective date of this interim rule, Missouri was classified as a Class A State.

To attain and maintain Class Free status, a State or area must (1) remain free from field strain Brucella abortus infection for 12 consecutive months or longer; (2) trace back at least 90 percent of all brucellosis reactors found in the course of MCI testing to the farm of origin; (3) successfully close at least 95 percent of the MCI reactor cases traced to the farm of origin during the consecutive 12-month period immediately prior to the most recent anniversary of the date the State or area was classified Class Free; and (4) have a specified surveillance system, as described above, including an approved individual herd plan in effect within 15 days of locating the source herd or recipient herd.

The last brucellosis-infected cattle herd in Missouri was depopulated in October 2002. Since then, no brucellosis-affected herds have been detected.

After reviewing the brucellosis program records for Missouri, we have concluded that this State meets the standards for Class Free status. Therefore, we are removing Missouri from the list of Class A States in § 78.41(b) and adding it to the list of Class Free States in § 78.41(a). This action relieves certain restrictions on moving cattle interstate from Missouri.

Immediate Action

Immediate action is warranted to remove unnecessary restrictions on the interstate movement of cattle from Missouri. Under these circumstances, the Administrator has determined that prior notice and opportunity for public comment are contrary to the public interest and that there is good cause under 5 U.S.C. 553 for making this action effective less than 30 days after publication in the Federal Register.

We will consider comments we receive during the comment period for this interim rule (see DATES above). After the comment period closes, we will publish another document in the Federal Register. The document will include a discussion of any comments we receive and any amendments we are making to the rule.

Executive Order 12866 and Regulatory Flexibility Act

This rule has been reviewed under Executive Order 12866. For this action, the Office of Management and Budget has waived its review under Executive Order 12866.

Cattle moved interstate are moved for slaughter, for use as breeding stock, or for feeding. Changing the brucellosis status of Missouri from Class A to Class Free will promote economic growth by reducing certain testing and other requirements governing the interstate movement of cattle from this State. Testing requirements for cattle moved interstate for immediate slaughter or to quarantined feedlots are not affected by this change. Cattle from certified brucellosis-free herds moving interstate are not affected by this change.

The groups affected by this action will be herd owners in Missouri, as well as buyers and importers of cattle from this State.

There are an estimated 61,500 cattle operations in Missouri that may be affected by this rule. About 99 percent of these are owned by small entities. Test-eligible cattle offered for sale interstate from other than certified-free herds must have a negative test under present Class A status regulations, but not under regulations concerning Class Free status. If such testing were distributed equally among all animals affected by this rule, Class Free status would save owners of cattle operations approximately $3 to $4 per head.

Therefore, we believe that changing the brucellosis status of Missouri will not have a significant economic effect on the small entities affected by this interim rule.

Under these circumstances, the Administrator of the Animal and Plant Health Inspection Service has determined that this action will not have a significant economic impact on a substantial number of small entities.
