**Rising Tuberculosis Cases in Baja California Due to Infected Cattle**
Between 2020 and January 2025, Baja California recorded 12,868 cases of pulmonary and extrapulmonary tuberculosis, resulting in 1,508 fatalities, despite the disease being preventable and treatable. The region ranks first in Mexico for both incidence and mortality rates per 100,000 inhabitants. Most of these cases are concentrated in Tijuana, with a significant number linked to the bacterium Mycobacterium bovis, transmitted from cattle to humans.
A study by the Autonomous University of Baja California highlights the increasing human-to-cattle transmission. As of December 2024, the state remains within the lower status of bovine tuberculosis control, not making substantial progress towards eradication. The National Campaign Against Bovine Tuberculosis shows minimal improvement, with little change in quarantine numbers. Certification of tuberculosis-free herds has significantly declined from 131 herds in 2020 to just 55 by 2024.
Baja California’s cattle sector lags behind Baja California Sur in funding and accreditation readiness, affecting the ability to export cattle to the U.S. The governmental efforts have been criticized for lacking effectiveness, with authorities not enforcing rigorous measures to combat bovine tuberculosis. The regional livestock sector suffers from neglect, minimal incentives, and leadership that lacks technical expertise, according to former government employees.
Federal and state budgets, managed by local committees, are mostly used for payroll rather than implementing effective strategies, contributing to stagnating efforts. Meanwhile, the U.S. expresses concern over potential tuberculosis spread due to cross-border interactions. Achieving certification could boost local economies by allowing cattle to be sold at higher prices in the U.S.
Efforts to inspect cattle have been inconsistent, with significant areas still pending completion. Although proposals have been made to designate some areas as certifiable to the U.S. Department of Agriculture, divided zones pose challenges to compliance with international standards.
**Additional Insights: Rising Bovine and Human Tuberculosis Concerns in Baja California**
Research has shown that Mycobacterium bovis, responsible for bovine tuberculosis, is increasingly affecting humans in Baja California. The bacterium, though traditionally linked to consumption of infected dairy products, is now also causing pulmonary forms of the disease, which are contagious between people. This shift in transmission dynamics underscores the necessity for heightened public awareness and food safety measures.
Moreover, studies reveal that a portion of cheese products in the region is contaminated with the bacterium, suggesting active transmission. Despite the public health risks, there is insufficient promotion of safe food practices, particularly in areas with the highest cases of tuberculosis.
Healthcare providers in Baja California are witnessing challenges beyond wildlife transmission, including treatment-resistant tuberculosis strains. This has been exacerbated by socio-economic factors such as poverty and limited healthcare resources, as well as a lack of sustained medications, contributing to continuous community transmission.
Emphasizing the importance of robust infrastructure, increased collaboration across administrative levels, and addressing medication shortages, experts call for comprehensive intervention strategies to mitigate tuberculosis rates effectively.
