WHAT IS ORGANIC FOOD?
According to the United States Department of Agriculture’s (USDA) Agricultural Marketing Service, organic foods are foods produced using methods that exclude the use of synthetic pesticides or chemical fertilizers. Organic foods do not contain genetically modified organisms (GMOs) or chemical food additives and are not processed using irradiation or industrial solvents.
For many countries around the world, certified organic food production is highly regulated and the term “organic” refers to foods produced based on the standards set forth by these governments or international organizations.
CONVENTIONAL VS. PASTURED VS. ORGANIC FOODS
Over the years, demand for organic and natural poultry products has increased, mostly due to the perception that these products are safer and more wholesome than traditionally raised poultry. In the U.S., organic broiler production increased from 1.9 million in 2000 to more than 10.4 million in 2005. Organic layer production increased from 1.1 million in 2000 to 2.4 million in 2005.
Locating and identifying organic products was initially difficult and confusing to consumers without federal regulations, as consumers could not differentiate between organic, natural, locally grown, and pasture-raised foods. In 1990, the U.S. Congress passed the Organic Food Production Act (OFPA) to avoid confusion, prevent misinterpretation, and develop a uniform standard for organic food claims. In 2002, the USDA formed the National Organic Program (NOP) to establish and regulate national standards for production, handling and processing of organic foods.
CONVENTIONAL POULTRY PRODUCTION
Ninety-nine percent of the total poultry production in the U.S. is done in conventional housing systems. This refers to commercial broiler birds which are raised for six to eight weeks to achieve an average market weight of 2.5 to 3.9 kg. These birds are typically Cornish white or white rock breeds that have a high feed conversion rate. The birds are raised in environmentally controlled houses and are fed commercial feed that contains antimicrobials and dietary supplements.
PASTURE POULTRY PRODUCTION
The terms “pasture raised” and “free range” refer to birds that have been grown outdoors. They are exposed to fresh air, grass, and insects, a more natural environment. Some form of shelter is usually provided so that the birds are protected from the elements. Some pasture flocks are raised in lightweight movable pens, which are moved daily or weekly, depending on the availability of pasture space. In this system, the grass is supplemented with commercial feed and they have access to whatever insects they can find in their enclosures. Pastured poultry is not regulated.
ORGANIC POULTRY PRODUCTION
The increased need for a more natural product without additives to enhance growth has been one of the driving factors for the continued demand of unconventionally produced food. Many consumers perceive that organically grown poultry products such as broiler chickens and eggs are safer and more nutritious than those grown under traditional conditions. The USDA defines organic foods distinctly from conventional products in growing, handling, and processing but not in safety and nutrition. The guidelines of the NOP for poultry produced in the organic program requires that poultry is raised without synthetic pesticides, antibiotics, hormones, andmammalian byproducts in the feed. Only organic and non-GMO feed ingredients are allowed for organic poultry production. Prebiotics, probiotics, and vaccines are allowed to replace antibiotic growth promoters, and there are potential growth deficiencies due to insufficient dietary sources of trace elements and minerals. These supplements have been approved for organic diets by the U.S. Food and Drug Administration (FDA). L-Methionine (MET) is an essential amino acid that is required for protein synthesis and the production of S-adenosyl-methionine (SAM), which is the primary methyl donor in metabolism. According to the USDA- NOP, all synthetic amino acids (AA) have been banned for use in organic poultry feeds except for methionine (USDA 2018). In addition to feed, living conditions and breeder sources are important factors when obtaining organic certification.
