Products such as ground beef, sausages or hams are dependent on many factors to result in a delicious end product. Fat content cannot be ignored or dismissed in that process.
Ground beef is sold in terms of fat/lean content, so every package has to meet the labeling requirements. An 80-20 package of ground beef that’s actually 90% lean costs the processor money through waste, and a package that is 70% lean is misleading to the customer and violates federal labeling laws.
