What do the organic rules require for dairy cows?
In the United States, milk can only be sold as organic by a certified operation. The federal rules (7 CFR Part 205) set the standards for the animals that produce it.
- Organic feed: producers must give a full diet of organically produced farm products, including pasture and forage.
- Pasture: ruminants must be managed on pasture with daily grazing through the grazing season. Dairy animals must get an average of at least 30 percent of their dry matter intake from grazing during that season.
- Outdoor access: all animals need year-round access to the outdoors, shade, shelter, exercise areas, fresh air and clean drinking water. Temporary confinement is allowed for reasons such as bad weather, health or milking.
Are antibiotics and hormones allowed in organic milk?
Growth hormones are not allowed: the rules bar giving hormones for growth promotion, production or reproduction, and bar feed that has had antibiotics added. A sick animal must still be treated, but an animal treated with antibiotics, or its products, cannot be sold or labeled as organic.
How long must a cow be organic before her milk is organic?
Dairy animals must be under organic management for at least 12 months immediately before milk is produced for sale as organic.
Does the label say anything about nutrition?
The sections we read set farming and handling rules. They do not make any claim about calories, vitamins or health effects, and we found no such claim in them. For questions about diet, ask a doctor or dietitian.
