OFFICIAL NUMBER.
Regulation 3.
If inspection is established under said application the Secretary of Agriculture will give said establishment a number by which all its meats and meat food products shall thereafter be known, and this number shall be used by the inspectors of the Department of Agriculture, and also by the proprietors of said establishment, to mark the meats and meat food products of the establishment as hereinafter prescribed. Establishments having one or more branches may use the same number for all by affixing a serial letter in connection with the number to differentiate the products of the different branches. Each establishment at which inspection is maintained must be separate and apart from any other establishment engaged in similar business at which inspection is not maintained.
(a) Retail butchers and dealers who have been exempted from inspection under these regulations will be given numbers by which their products will be known.
