Organic beef

Organic beef is beef grown according to organic food principles.
Organic beef.
According to the USDA National Organic Program (NOP) Standards rules passed on October 22, 2002, certified organic livestock, including beef, must come from a fully verifiable production system that collects information on the history of every animal in the program, including its breed history, veterinary care, and feed. Further, to be certified as organic, all cattle should meet the following criteria:
Organic vs. Natural.
With the arrival of the organic label, many assumed that the terms “organic” and “natural” were interchangeable, failing to understand the strict regulations required to raise certified organic beef. The USDA defines “natural” beef as minimally-processed beef without additives. Natural beef producers may choose not to use antibiotics or growth-promoting hormones, but there is no third-party verification system required by the USDA. Beef from feedlots can be labeled natural, according to the USDA’s definition.
The U.S. Department of Agriculture allows any fresh meat to be described as "natural" if it includes no artificial flavoring, coloring, preservative or any other artificial ingredient. Minimally processed products, such as ground meat, also count as "natural." To be marketed as "natural," the product can not contain any additives, such as monosodium glutamate or salt.
Grass-fed vs Grain-fed beef.
As organic cattle approach market weight, there are two feeding methods that producers most commonly use to deliver beef products to their customers: “grass-fed” and “grain-fed”. In the “grass-fed” program, the cattle continue to eat certified organic grass right up to the time of slaughter. The USDA is currently developing guidelines to define the term “grass-fed”, and it is expected to call for an all-grass diet of at least 95%. Strictly grass-fed cattle tend to be leaner than grain-fed. Grain-feeding produces cattle with a higher percentage of fat. All grains must be certified organic to ensure the integrity of the program.
