(a) Each shipping container of any meat, meat food product, or meat by-product inspected under the authority of this article and found to be wholesome and not adulterated, shall at the time such product leaves the official establishment bear, in distinctly legible form, the official inspection mark and the approved plant number of the official establishment in which the contents were processed. Each immediate container of any meat, meat food product or meat by-product inspected under the authority of this article and found to be wholesome and not adulterated, shall at the time such product leaves the official establishment bear, in addition to the official inspection mark, in distinctly legible form, the name of the product, a statement of ingredients if fabricated from two or more ingredients, including a declaration as to artificial flavors or colors, if any, the net weight or other appropriate measure of the contents, the name and address of the processor and the approved plant number of the official establishment in which the contents were processed. The name and address of the distributor may be used in lieu of the name and address of the processor if the approved plant number is used to identify the official establishment in which the article was prepared and packed. Each livestock carcass and each primal part of such a carcass shall bear the official inspection mark and approved plant number of the establishment. The Director may by rules or regulations require additional marks or label information to appear on livestock carcasses or parts thereof, meat food products or meat by-products when they leave the official establishments or at the time of their transportation or sale in this State, and he may permit reasonable variations and grant exemptions from the marking and labeling requirements of this paragraph in any manner not in conflict with the purposes of this article. Marks and labels required under this paragraph shall be applied only by, or under the supervision of an inspector.
(b) The use of any written, printed or graphic matter upon or accompanying any livestock carcass, or part thereof, meat food product or meat by-product inspected or required to be inspected pursuant to the provisions of this article, or the container thereof, which is false or misleading in any particular is prohibited. No livestock carcasses or parts thereof meat food products or meat by-products inspected or required to be inspected pursuant to the provisions of this article shall be sold or offered for sale by any person under any false or deceptive name; but established trade names which are usual to such articles and which are not false or deceptive and which shall be approved by the Director are permitted. If the Director has reason to believe that any label in use or prepared for use is false or misleading in any particular, he may direct that the use of the label be withheld unless it is modified in such manner as he may prescribe so that it will not be false or misleading. If the person using or proposing to use the label does not accept the determination of the Director, he may request a hearing, but the use of the label shall, if the Director so directs, be withheld pending hearing and final determination by the Director. Any such determination by the Director shall be conclusive unless within thirty days after the receipt of notice of such final determination the person adversely affected thereby appeals to the court of common pleas or county court of the county in which he has his principal place of business.
