    Jerry,

    Uniformity of size refers to the degree of uniformity of the shrimp in the
    container to determine their conformity to the declared count. The product
    shall be evaluated in the fresh or thawed state for uniformity of size as
    follows:
    (A) From the adjusted sample unit (all whole, unbroken, undamaged shrimp in
    the sample unit) visually select and weigh not more than 10 percent by
    count, but not less than one, of the largest shrimp.

    (B) Visually select and weigh not more than 10 percent by count, but not
    less than one, of the smallest shrimp.

    (C) Divide the weight of the large shrimp by the weight of the small shrimp
    and the result will be the uniformity ratio.
