diseased excluded. Slaughter houses and meat-packing
establishments where meat is packed for interstate or foreign
commerce are inspected; meat that is unfit for use being
condemned, while that which is good has the government stamp
placed upon it. Such measures are primarily health measures (see
Chapter XX), but they have great economic value.

In a similar manner imported seeds, plants, and plant products are
inspected to prevent the importation of plant diseases and plant
pests, and also to prevent adulteration of plant products.
Warehouses are inspected and licenses granted to those that are
suitable for the proper storage of cotton, grains, tobacco,
flaxseed, and wool. The Department enforces the laws that fix the
standards for grading cotton and grain, and licenses grain
inspectors. It also enforces the Food and Drugs Act (see Chapter
XX).
