Historical archives reveal that municipal authorities in Saltillo, Coahuila, distributed poisoned meat to reduce the stray dog population in 1929 [1].

These records provide a window into early 20th-century urban management and the drastic measures cities once employed to handle public health crises. The discovery highlights the evolution of animal welfare standards and municipal policy in Mexico.

The city government at the time targeted the overpopulation of stray dogs to address specific public health concerns [1]. To achieve this, officials distributed poisoned meat, which were referred to as "bocados" [1]. This method was deployed across the city to systematically lower the number of roaming animals.

Saltillo's approach in 1929 reflects a period when urban centers prioritized immediate sanitation and disease prevention over the ethical treatment of animals. The use of poisoned bait was a common, albeit brutal, strategy used by various administrations globally during that era to manage wildlife and domestic animals that had become feral.

The archival findings emerge from documents detailing the city's historical efforts to maintain order and health within the municipality [1]. While the records do not specify the exact number of animals affected, they confirm that the distribution of poisoned meat was an official government action.

Modern animal control strategies have since shifted toward sterilization and shelters. The contrast between the 1929 "bocados" method and current veterinary science underscores a fundamental shift in how municipal governments perceive their responsibility toward animal populations in urban environments [1].

This historical revelation illustrates the transition from eradication-based pest control to the modern humane management of urban animals. By documenting the use of poison in 1929, historians can trace the development of public health laws and the eventual rise of animal rights movements in Mexico, moving away from state-sponsored culling toward sustainable population control.
