              EXTERNAL PARASITE CONTROL RECOMMENDATIONS FOR SWINE

                                 Introduction

Keys to pesticide safety:
    1.  Before using any pesticide, stop and read the precautions.
    2.  Read the label on each pesticide container before each use.  Heed all
        warnings and precautions.
    3.  Store all pesticides in their original containers away from food or
        feed.
    4.  Keep pesticides out of the reach of children, pets and livestock.
    5.  Apply pesticides only as directed.
    6.  Dispose of empty containers promptly and safely.

Recommendations in this guide are for guidelines only.  The user must insure
that the pesticide is applied in strict compliance with label directions.

The Food and Drug Administration has established residue tolerances for
certain insecticides in the meat of certain animals.  When these and other
approved insecticides are applied according to recommendations, the pests
should be effectively controlled and the animals' products will be safe for
food.

The improper use of insecticides may result in residue in milk or meat.  Such
products must not be delivered to processing plants.

To avoid excessive residues, use the insecticides recommended at the time
recommended and in the amounts recommended.

The use of trade names is solely for the purpose of providing specific
information.  It is not a guarantee or warranty of the products named and does
not signify that they are approved to the exclusion of others.
