DeJong,\nThe U.S. Food and Drug Administration (FDA) conducted an inspection of your dairy operation, located at 102218 Draper Road, Dorchester, Wisconsin 54425 on April 6 and April 8, 2026. This letter notifies you of the significant violations of the Federal Food, Drug, and Cosmetic Act (FD&C Act) that were found during our inspection of your operation.

We received your response dated April 13, 2026, and have reviewed them below in relation to each noted violation.\nAdulteration of New Animal Drugs\nOur inspection found you did not use (b)(4) ((b)(4)) for intramammary infusion in accordance with its approved labeling and your veterinary prescription. Use of a drug in a manner that is not consistent with its labeling is extralabel use.1\nThe manufacturer’s label for (b)(4)® states, “(b)(4)”. However, our inspection found that your treatment of multiple cows failed to conform with these directions. You administered one syringe once a day in affected quarters for three consecutive days for the following cows:\nCow with ear tag (b)(4) was treated once a day with one syringe in affected quarters on August 15 through 17, 2025.\nCow with ear tag (b)(4) was treated once a day with one syringe in affected quarters on August 22 through 25, 2025.\nCow with ear tag (b)(4) was treated once a day with one syringe in affected quarters on January 11 through 13, 2026.\nSince you did not follow the labeled directions, you used the drug in an extralabel manner. The extralabel use of approved animal or human drugs is only allowed if the extralabel use complies with the FD&C Act, including that the use must be by or on the lawful order of a licensed veterinarian within the context of a valid veterinarian-client-patient relationship,2 and 21 CFR 530.3 Your extralabel use of this drug was not done in accordance with an order from a licensed veterinarian, in violation of 21 CFR 530.11(a). Because your extralabel use of this drug was not in compliance with the FD&C Act and 21 CFR 530, you caused the drugs to be unsafe and adulterated.4 The doing of any act to a food or drug after shipment of the food or drug and\u002For its components in interstate commerce and while the food or drug is held for sale (whether or not the first sale) that results in the food or drug being adulterated or misbranded is a prohibited act.5\nEvaluation of your response:\nWe reviewed your emailed response dated April 13, 2026. Your response does not provide enough details for us to adequately evaluate the effectiveness and sustainability of your actions. You did not provide supporting documentation that you trained your employees in the proper use of the medications they administer to your animals. You also did not provide supporting documentation, such as treatment records, demonstrating the correct use of (b)(4) and other drugs at your dairy.\nConclusion\nThis letter is not intended to be an all-inclusive statement of violations that may exist at your facility. You are responsible for investigating and determining the causes of any violations and for preventing their recurrence or the occurrence of other violations. It is your responsibility to ensure that you comply with all requirements of federal law and FDA regulations.\nThis letter notifies you of our concerns and provides you with an opportunity to address them. You should take prompt action to correct any violations. Failure to adequately address any violation may lead to regulatory, or where appropriate, legal action.\nWithin fifteen (15) working days of receipt of this letter, please notify this office in writing of the specific steps that you have taken to correct any violations.

If you cannot complete corrective action within fifteen (15) working days, state the reason for the delay and the time within which you will complete the correction.
