Stability returns in parts of Mexico after CJNG violence

Relative calm is beginning to return in parts of Mexico after one of the country’s most consequential cartel shocks in years: the February 22, 2026 killing of CJNG leader Nemesio Oseguera Cervantes, or El Mencho. Ackerman Group said Mexican security forces had contained much of the immediate retaliatory violence and were working to reopen transit corridors, though Jalisco and Nayarit remained areas of concern.

The violence erupted within hours of the military operation in Tapalpa, Jalisco, where Mexican forces fatally wounded Oseguera during an attempted capture operation. AP reported that cartel retaliation quickly spread across at least 20 states, with more than 250 roadblocks, burned vehicles, canceled classes, and deaths that included members of the security forces. The scale of the response illustrated both CJNG’s geographic reach and the extent to which its operations had been tied to Oseguera’s leadership. (apnews.com)

Ackerman Group’s follow-up assessment suggested the worst of the immediate disruption had started to ease within days. It reported that around 10,000 soldiers had been deployed, including roughly 2,000 in and around Guadalajara, and that normal activity appeared to be resuming in many affected states. Even so, the firm said disturbances were still being reported in Jalisco and Nayarit, and warned that airport access, highway travel, and local business operations could remain volatile with little notice.

That matters beyond traveler safety. Road insecurity and stop-start transport conditions can disrupt the movement of animals, feed, veterinary pharmaceuticals, biologics, laboratory materials, and inspection personnel. While this incident was not an animal disease event, it landed in a region that intersects with major agricultural and export activity. Separate reporting during the unrest indicated that some USDA APHIS personnel in Mexico were instructed to avoid certain worksites, and a produce trade outlet reported a temporary pause in some on-site inspection activity before operations resumed. That’s a reminder that security incidents can interfere with the practical infrastructure behind animal health surveillance and cross-border trade, even when no formal veterinary restriction has been announced.

On the policy side, the U.S. State Department’s Mexico travel advisory predates this incident, but the embassy and consular network issued security alerts during the February violence, including shelter-in-place guidance for some locations. Ackerman later said the stricter posture had eased in some states as conditions stabilized. Although the embassy’s final-update page was not fully accessible in this search session, multiple contemporaneous reports support the broader arc: an acute security lockdown followed by a cautious reopening of movement in some areas.

Expert commentary points to a more complicated second phase. AP quoted David Mora of International Crisis Group saying the return of El Mencho’s body to his family was unlikely to recreate the initial havoc, but that the next violence could look different as the cartel reorganizes and smaller groups compete. Ackerman made a similar assessment, warning that if CJNG fragments, the result could be more targeted attacks and prolonged instability rather than the highly visible roadblock campaign seen immediately after the killing.

Why it matters: Veterinary professionals tracking disease surveillance, livestock movement, or cross-border operations should read this as a logistics and continuity story. In Mexico and along the U.S.-Mexico interface, veterinary systems depend on safe road access, functioning inspection programs, reliable staffing, and predictable movement of animals and products. A security crisis in Jalisco and nearby corridors can complicate everything from ambulatory service and sample transport to export certification and emergency response readiness. For clinics, producers, and animal health companies, the practical question is whether staff and goods can move safely, not just whether formal trade rules have changed. (ackermangroup.com)

What to watch: Watch for signs of CJNG succession or fragmentation, any renewed U.S. or Canadian security alerts, and any knock-on effects on inspection, certification, or agricultural transport in western Mexico over the coming weeks. (ackermangroup.com)
