    ACTION: Final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: FSIS is amending the Federal meat inspection regulations to 
    permit the use of carbon dioxide to induce death in swine. The 
    amendment, prompted by a petition from the Danish and Swedish Meat 
    Research Institute, is based on scientific research showing the use of 
    carbon dioxide to induce death in swine to be an effective and humane 
    slaughtering method.
    
    EFFECTIVE DATE: May 26, 1994.
    
    FOR FURTHER INFORMATION CONTACT: Dr. William O. James, Director, 
    Slaughter Inspection Standards and Procedures Division, room 202 Annex 
    Building, FSIS, USDA, 300 12th Street SW., Washington, DC 20250-3700, 
    (202) 720-3219.
    
    SUPPLEMENTARY INFORMATION:
    
    Executive Order 12866
    
        This final rule has been determined to be not-significant for 
    purposes of Executive Order 12866 and therefore has not been reviewed 
    by the Office of Management and Budget.
    
    Executive Order 12778
    
        This final rule has been reviewed pursuant to Executive Order 
    12778, Civil Justice Reform. This final rule will permit swine to be 
    humanely slaughtered in official meat-packing establishments through 
    the administration of carbon dioxide.
        State and local jurisdictions are preempted under the Federal Meat 
    Inspection Act (FMIA) from imposing any requirements with respect to 
    federally inspected premises and facilities, and operations of such 
    establishments, that are in addition to, or different than, those 
    imposed under the FMIA. States and local jurisdictions are also 
    preempted under the FMIA from imposing any marking, labeling, 
    packaging, or ingredient requirements on federally inspected meat or 
    meat food products that are in addition to, or different than, those 
    imposed under the FMIA. States and local jurisdictions may, however, 
    exercise concurrent jurisdiction over meat products that are outside 
    official establishments for the purposes of preventing the distribution 
    of meat products that are misbranded or adulterated under the FMIA or, 
    in the case of imported articles, which are not at such an 
    establishment, after their entry into the United States. States and 
    local jurisdictions may also make requirements or take other actions 
    that are consistent with the FMIA, with respect to any other matters 
    regulated under the FMIA.
        Under the FMIA, States that maintain meat inspection programs must 
    impose requirements on State-inspected products and establishments that 
    are at least equal to those required under the FMIA. These States may, 
    however, impose more stringent requirements on such State-inspected 
    products and establishments.
        No retroactive effect will be given to this final rule, and 
    applicable administrative procedures must be exhausted before any 
    judicial challenge can be taken to the application of these provisions. 
    Those administrative procedures are set forth in 9 CFR 306.5.
    
    Effect on Small Entities
    
        The Administrator has determined that this final rule will not have 
    a significant economic impact on a substantial number of small 
    entities, as defined by the Regulatory Flexibility Act (5 U.S.C. 601).
        The use of the carbon dioxide (CO2) slaughtering methods is 
    voluntary. FSIS is not aware of any domestic establishments that are 
    currently planning to use this swine slaughtering method. Even if some 
    establishments decide to use the method, there is no indication that a 
    substantial number of establishments will. There will be no impact on 
    entities other than establishments engaged in the slaughter of swine 
    and the sale of swine carcasses and parts for human food. A significant 
    investment will be required by large or small entities establishing 
    CO2 slaughtering facilities. Inspection program experts estimate 
    that an investment of $50,000 to $100,000 per slaughtering line would 
    be necessary, depending on the size and complexity of the 
    establishment. The decision to make this initial investment will be 
    entirely up to the establishment, although this rule authorizing 
    CO2 slaughtering of swine could be a factor in making the 
    decision. This investment could be more than offset by a reduction in 
    manpower required for restraining, stunning, and handling hogs after 
    stunning.
        Further, the improvement in meat quality, which advocates of the 
    CO2 process claim, could lead to a greater amount of saleable 
    product. Because the hogs are much more relaxed when slaughtered with 
    CO2 than they are when slaughtered by current methods, a number of 
    desirable characteristics are imparted to the meat. The amount of pale, 
    soft, exudative pork, considered undesirable by meat buyers, is reduced 
    under the process, as well as blood spattering and broken bones. Also, 
    less effort is expended on trimming and the removal of quality defects.
        No adverse competitive effects on small entities resulting from 
    adoption of the rule are anticipated. Because the equipment needed for 
    establishments to benefit from CO2 slaughtering is available in a 
    range of prices, larger establishments choosing to use this method will 
    not receive greater proportional advantages than smaller ones choosing 
    to do the same. For the reasons discussed above, the rule will not have 
    a significant impact on a substantial number of small entities.
    
    Paperwork Requirements
    
        This final rule imposes no new information collection requirements 
    on official establishments or other members of the public. Under the 
    rules for the use of carbon dioxide to anaesthetize animals before 
    slaughter, establishments are required to sample gas for analysis from 
    representative locations within the gas tunnels which convey the 
    animals. Gas concentrations and exposure times are to be recorded 
    throughout each day's operations. These records are subject to FSIS's 
    standard records retention requirement at 9 CFR 320.3 and must be 
    available to employees of the inspection service. These carbon dioxide 
    monitoring requirements are continued under this final rule.
    
    Background
    
        Under the Humane Slaughter Act (HSA) of 1958 (7 U.S.C. 1901-1906), 
    as amended, the Secretary of Agriculture is authorized to designate 
    humane methods of handling and slaughter of food animals. The HSA 
    (section 2 (a) ) sets forth in number of methods of handling and 
    slaughtering that have been found to be human, including the 
    anaesthetization of animals by electrical or chemical means before they 
    are shackled, hoisted, thrown, cast, or cut. These methods are 
    available to slaughtering establishments under the FMIA (section 3; 21 
    U.S.C. 603).
        FSIS was petitioned by the Danish and Swedish Meat Research 
    Institute to amend the Federal meat inspection regulations to permit 
    the use of CO2 for the purpose of inducing death in swine. The 
    petitioners based their request on studies demonstrating the beneficial 
    effects of this method on meat quality and the efficient handling of 
    slaughter swine. Some Danish firms that export product to the Untied 
    States are planning to install systems for slaughtering swine with 
    CO2, and FSIS believes it may be potentially beneficial to U.S. 
    industry to make generally available the option of this use of 
    CO2.
        The use of CO2 gas for stunning has been permitted since the 
    early 1900's and is permitted by the HSA. Animals to be anaesthetized 
    by this method are placed on a conveyor and passed through tunnels 
    filled with the gas. They are moved through the tunnels at such a slow 
    rate that they are unconscious when they emerge. They are then 
    shackled, hoisted, stuck, and bled out.
        In the last two decades, reports in the scientific literature have 
    shown that the stunning of slaughter animals by the administration of 
    CO2 gas is just as effective as electrical stunning. There is 
    little or no difference between the two methods in the amount of stress 
    inflicted on the animal. Whichever method is used, animals should be 
    carefully handled before slaughter to reduce stress, and sticking 
    (exsanguination) should take place as soon as possible after stunning 
    to prevent a return to consciousness.
        With respect to the administration of CO2, it has been 
    demonstrated that if the concentration of the gas in the tunnels is 
    increased, death ensues. Other effects, including fewer injuries to the 
    animals or establishment employees, have also been noted. Depending on 
    the facilities and equipment used and the technique of administration, 
    CO2 stunning of swine can yield meat that has improved color, 
    carcasses with fewer broken bones and blood spots in the most desired 
    cuts, less pale, soft, exudative pork, and higher boning and cutting 
    yields.
        Studies have shown that the necessary conditions for death to take 
    place are a 95-98 percent CO2 concentration and an exposure time 
    of 3.5 minutes. The death-to-bleeding interval should be no longer than 
    2 minutes to prevent pooling of blood in intestines and edible organs 
    and no longer than 5 minutes to prevent the pooling of blood in muscle 
    tissue.
        Under the FMIA, only those foreign establishments that have 
    complied with inspection standards ``at least equal to'' those enforced 
    domestically by the United States Government may export product to this 
    country. An establishment in which slaughter methods are used that are 
    prohibited by regulations under the FMIA is not eligible to export 
    product to the United States. Without the change in the regulations 
    effected by this final rule, an establishment using CO2 to induce 
    death in swine would be unable to export pork products to the United 
    States.
    
    Comments on the Proposed Rule
    
        On September 10, 1993, FSIS published in the Federal Register (58 
    FR 47673) a proposed rule to amend the Federal meat inspection 
    regulations to allow official establishments to induce death in swine 
    by the use of carbon dioxide. The Agency received two comments, one 
    from an industry consultant, and one from a swine processor. Both 
    commenters supported the proposed change in the regulations, citing 
    research indicating the process is safe and humane. One of the 
    commenters expressed the belief that use of the carbon dioxide 
    slaughter process would encourage operators and suppliers to develop 
    improved methods of handling and slaughtering swine.
    
    Final Rule
    
        The Agency is, therefore, amending Sec. 313.5 of the Federal meat 
    inspection regulations to remove the prohibition against the use of 
    CO2 as a direct cause of asphyxiation or death in swine and 
    provide for monitoring of the conditions under which slaughter by use 
    of CO2 gas is administered. This amendment is consistent with the 
    main purpose of the HSA, which is to render animals insensible to pain 
    before slaughter. The change will not require swine to be asphyxiated 
    by CO2 before bleeding, but will permit exposure to concentrations 
    of the gas for a sufficient amount of time for death to occur. In 
    addition, the requirement for a suitable exhaust system (9 CFR 313.5 
    (b)(3)) has been amended to more accurately state the system's purpose, 
    which is, in case of equipment breakdown, to prevent both nonuniform 
    carbon dioxide concentrations in the gas tunnel and leakage of carbon 
    dioxide gas into the ambient air of the establishment.
    
    List of Subjects in 9 CFR Part 313
    
        Humane slaughter of livestock, Meat inspection.
    
        For the reasons set out in the preamble, 9 CFR part 313 of the 
    Federal meat inspection regulations is amended as follows:
    
    PART 313--HUMANE SLAUGHTER OF LIVESTOCK
    
        1. The authority citation for part 313 continues to read as 
    follows:
    
        Authority: 7 U.S.C. 1901-1906; 21 U.S.C. 601-695; 7 CFR 2.17, 
    2.55.
    
        2. Paragraph (a)(1) of Sec. 313.5 is amended by adding a new last 
    sentence; paragraphs (a)(3), (b)(1)(i), and the last sentence of 
    paragraph (b)(3) are revised to read as follows:
    
    
    Sec. 313.5  Chemical; carbon dioxide.
    
    * * * * *
        (a)  * * *
        (1)  * * * In swine, carbon dioxide may be administered to induce 
    death in the animals before they are shackled, hoisted, thrown, cast, 
    or cut.
        (2) * * *
        (3) On emerging from the carbon dioxide tunnel, the animals shall 
    be in a state of surgical anaesthesia and shall remain in this 
    condition throughout shackling, sticking, and bleeding, except for 
    swine in which death has been induced by the administration of carbon 
    dioxide. Asphyxia or death from any cause shall not be produced in 
    animals before bleeding, except for swine in which death has been 
    induced by the administration of carbon dioxide.
        (b) * * *
        (1) * * *
        (i) The carbon dioxide gas shall be administered in a tunnel which 
    is designed to permit the effective exposure of the animal. Two types 
    of tunnels, based on the same principle, are in common use for carbon 
    dioxide anesthesia. They are the ``U'' type tunnel and the ``Straight 
    Line'' type tunnel, and are based on the principle that carbon dioxide 
    gas has a higher specific gravity than air. The tunnels are open at 
    both ends for entry and exit of animals and have a depressed central 
    section. Anesthetizing, or, in the case of swine, death-inducing, 
    carbon dioxide concentrations are maintained in the central sections of 
    the tunnels. Effective anaesthetization is produced in these central 
    sections. Animals are driven from holding pens through pathways 
    constructed of large-diameter pipe or smooth metal and onto continuous 
    conveyor devices that move the animals through the tunnels. The animals 
    are either compartmentalized on the conveyors by mechanical impellers 
    synchronized with the conveyor or they are otherwise prevented from 
    crowding. While impellers are used to compartmentalize the animals, 
    mechanically or manually operated gates are used to move the animals 
    onto the conveyors. Surgically anaesthetized animals, or killed swine, 
    are moved out of the tunnels by the same continuous conveyors that 
    moved them into and through the carbon dioxide gas.
        (2)  * * *
        (3)  * * * An exhaust system must be provided so that, in case of 
    equipment failure, non-uniform carbon dioxide concentrations in the gas 
    tunnel or contamination of the ambient air of the establishment will be 
    prevented.
