§ 119.59 Retests when serum found "unsatisfactory for potency."

When a test of anti-hog-cholera serum, prepared at a licensed establishment, has shown it to be "unsatisfactory for potency," the serum may be tested again as prescribed in § 119.51. Should this retest show the serum to be "unsatisfactory for potency" it may be so retested again, and if still found "unsatisfactory for potency" the serum shall be destroyed or otherwise disposed of as prescribed by the Director.

§ 119.60 Tests for purity.

Should abscesses develop at the sites of the serum inoculations in any of the pigs used at licensed establishments for testing serum as provided in this part, the following rules shall apply:

(a) Judgment of the results of tests made on pigs to determine the potency of anti-hog-cholera serum will be rendered irrespective of conditions found which are regarded as an index to the purity of the product.

(b) If anti-hog cholera serum upon testing is declared "satisfactory for purity," and it is found necessary to subject the batch of serum to a retest to determine its potency, judgment concerning the purity of the product shall be based on the first test unless evidence is found subsequent to such test which indicates that the serum is contaminated. § 119.61 Retests for purity.

(a) When anti-hog-cholera serum prepared at a licensed establishment has once been found "unsatisfactory for purity," as defined in § 119.58, it may be tested again for purity on eight pigs, provided each pig receives a single injection, in the axillary space, of at least 20 cc. of the product.

(b) When anti-hog-cholera serum produced at a licensed establishment has twice been found "unsatisfactory for purity," as defined in § 119.58, but is "satisfactory for potency," as provided in § 119.58, it may be tested again to ascertain whether it is contaminated with pus-producing organisms by treating 50 hogs on the premises of the licensed establishment. Each hog treated shall receive a single injection, in the axillary space, of not less than 25 cc. of the product to be tested. Serum tested as provided in this paragraph shall be destroyed or otherwise disposed of or used as prescribed by the Director.

§ 119.62 Purity test animals; holding period.

Animals used for testing serum as provided in § 119.61 at licensed establishments shall be held for at least 14 days, and be carefully examined at the sites of inoculations to determine whether the serum has caused abscess formation. § 119.63 Minimum dosage.

Anti-hog-cholera serum or hog cholera antibody-concentrate may be marketed if, upon testing, as provided in Parts 101 to 122 of this subchapter, it is found "satisfactory for potency" and "satisfactory for purity," provided the label on the true container thereof contains recommendations for use as specified in this section:

(a) For use in preventive vaccination, the minimum dose shall be 10 cc or more of anti-hog-cholera serum or 5 cc or more of hog cholera antibody-concentrate when used with modified live virus hog-cholera vaccine, plus the following statement: "If immediate protection against hog cholera is desired or movement of the animals from the premises is anticipated within 21 days following immunization, 15 cc or more of anti-hogcholera serum or 72 cc or more of hog cholera antibody-concentrate should be administered simultaneously with the vaccine."

(b) Export labels only may contain recommendations for use with simultaneous virus in doses not less than those appearing in the following table:

duced at licensed establishments expire before the serum is used, the serum may be retested, and if found "satisfactory for potency” and “satisfactory for purity," as defined in § 119.58 (b) and (e), the expiration date may be extended for 1 year from the date of conclusion of the retest for potency. Should a batch of anti-hog-cholera serum not be found "satisfactory for potency" or "satisfactory for purity" before the expiration of 3 years from the date of collection of the oldest serum in the batch, or should it not be so found in time to allow it to be used before the expiration of said 3 years, the expiration date will be limited to 6 months from the date of conclusion of a satisfactory test for potency.
