This Policy Book is assembled in dictionary form and may be used in conjunction with the Meat and Poultry Inspection Regulations and the Meat and Poultry Inspection Manual, Directives and Notices. It is a composite of policy and day-to-day labeling decision, many of which do not appear in the above publications. They are subject to change and therefore a periodic updating of this book will take place. Note: Red Meat -- Required percentages of meat required for red meat products are shown on the basis of fresh uncooked weight unless otherwise indicated. For purposes of this Policy Book, whenever the terms beef, pork, lamb, mutton, or veal are used they indicate the use of skeletal muscle tissue from the named species (9 CFR 301.2). Note: Poultry-- Required percentages for poultry products are based on a cooked deboned basis unless otherwise stated. When the standards indicate "poultry", the skin and fat are not to exceed natural proportions per (9 CFR 381.117(d)).
