FDA WARNING_LETTER - Riedstra Dairy, Ltd. - November 02, 2021

On February 4, 2022, the FDA issued a Warning Letter to Riedstra Dairy, Ltd. following an inspection from September 2 to November 2, 2021. The letter details violations of the Federal Food, Drug, and Cosmetic Act.

The FDA found that Riedstra Dairy offered an adulterated animal for human consumption.

This renders the food adulterated under section 402(a)(2)(C)(ii) of the FD&C Act.

Deficiencies included incomplete and inaccurate treatment records (e.g., unrecorded treatments, missing routes of administration) and a lack of a drug inventory system.

The new animal drug (b)(4) (ceftiofur hydrochloride) was also found to be adulterated (21 U.S.C. § 351(a)(5)) due to extra-label
