Texas couple sentenced in smuggled veterinary drugs case

A Texas couple who operated a website selling smuggled veterinary drugs and pesticides from Mexico has now been sentenced, closing a case that federal agencies framed as both an animal health and environmental enforcement matter. On September 8, 2026, the Justice Department said Garland residents Thao Duong and Lam Mai were sentenced after selling FDA-unapproved veterinary drugs and EPA-unregistered pesticides nationwide. Duong was sentenced to three months in prison, two years of supervised release, and forfeiture of more than $1.5 million; Mai received two years of probation. (justice.gov)

The case had been building since at least January 20, 2026, when the couple pleaded guilty. According to DOJ, Duong pleaded guilty to conspiring to smuggle and sell unregistered pesticides and misbranded veterinary drugs, while Mai pleaded guilty to conspiring to sell those products through the website. Federal agencies said the products had been smuggled into the U.S. from Mexico, then distributed to customers around the country. (justice.gov)

The government’s concern centered not just on unlawful importation, but on the nature of the products themselves. DOJ identified the pesticides Taktic and Bovitraz as containing amitraz. EPA says amitraz products used improperly in beehives can expose bees and contaminate honey, honeycomb, and beeswax, creating potential human exposure concerns. EPA’s advisory on varroa-mite control also makes clear that distributing unregistered pesticide products for use in beehives can violate federal pesticide law. (justice.gov)

On the veterinary drug side, FDA’s framework is straightforward: new animal drugs generally must have an approved or conditionally approved application, an index listing for certain minor-species uses, or another specific legal basis to be marketed in the U.S. FDA also says unapproved veterinary drugs may not be legally imported except in limited circumstances, and products entering outside those channels can be detained or refused. In practice, that means a product’s availability online, or its routine use in another country, doesn’t make it lawful or appropriate for U.S. clinical use. (fda.gov)

Federal officials used the sentencing to emphasize the broader enforcement message. DOJ said the defendants “traded human safety and environmental health for illicit profit,” while FDA’s Office of Criminal Investigations said smuggling and distributing misbranded, unapproved veterinary drugs “jeopardize the health of animals.” Those statements align with FDA CVM’s larger compliance posture, which focuses on protecting both animal and human health when products bypass approval, labeling, manufacturing, and import controls. (justice.gov)

Why it matters: For veterinarians, this case sits at the intersection of pharmacology, client education, and regulatory risk. Clinics may encounter pet parents, producers, or hobbyists who buy lower-cost imported products online, particularly for parasite control or food-animal use. But if those products are unapproved, misbranded, or unregistered, practitioners face unanswered questions about formulation quality, dose consistency, residue avoidance, withdrawal guidance, and adverse-event reporting. The issue is especially sensitive when products could affect the food chain or adjacent sectors such as apiculture. (fda.gov)

The case also reinforces a practical point for veterinary teams: regulatory status matters as much as active ingredient familiarity. Amitraz itself has lawful uses in certain registered or approved contexts, but EPA and DOJ drew a sharp distinction between regulated products and smuggled, unregistered ones. Likewise, FDA notes that legitimate animal drugs typically carry approval identifiers and move through regulated import and distribution channels. That distinction is likely to matter more, not less, as federal agencies continue targeting online and cross-border sales that evade oversight. (epa.gov)

What to watch: The next signal will be whether this sentencing is followed by more coordinated FDA-EPA-DOJ enforcement actions involving online marketplaces, border seizures, or warning activity tied to imported animal health products. Given recent federal messaging around illicit imports and pesticide distribution, veterinary professionals should expect continued attention to products sold outside approved U.S. channels.
