ALBANY, N.Y. (AP) — New York's attorney general has announced an agreement with an herbal supplement maker to implement new quality control measures to confirm the authenticity of its products.

The settlement with Long Island-based NBTY follows earlier agreements by Attorney General Eric Schneiderman (SHNEYE'-dur-muhn) with GNC and Nature's Way.

His office last year wrote to several makers of herbal products, demanding detailed ingredient and quality control information on products they sell in the state.

The new agreement calls for NBTY to phase in DNA barcoding on herbal ingredients within two years and implement annual testing to detect allergens like peanuts, milk, soy, eggs and wheat in products.

NBTY said there was no evidence it failed to comply with FDA requirements and that they are committed to promoting reliable testing for herbal dietary supplements.
