On the evening of April 21, 2026, a significant fire broke out in the vicinity of the Sonora Market and La Merced area in Mexico City, prompting an immediate response from emergency services. The blaze, which began around 23:17 CST, quickly spread through a cluster of semi-fixed commercial stalls near the market complex, leading to the evacuation of approximately 200 people from nearby buildings and market areas. Footage shared on social media showed large flames engulfing rows of temporary structures, with thick smoke visible across the skyline of the Cuauhtémoc borough.
According to preliminary reports from local authorities and verified by multiple news outlets, the fire affected around 50 semi-fixed commercial units, commonly used by vendors selling traditional goods, food and crafts in the informal market zones surrounding the Sonora and La Merced markets. These semi-fixed structures, often made of wood, plastic, and metal sheeting, are particularly vulnerable to rapid fire spread due to their close proximity and flammable materials. No fatalities were reported in the initial response, though several individuals were treated for smoke inhalation and minor burns at local medical facilities.
Emergency teams from the Mexico City Fire Department (Heroico Cuerpo de Bomberos de la Ciudad de México) and the Secretaría de Seguridad Ciudadana (SSC) were deployed to the scene to contain the flames and prevent further spread to adjacent buildings, including historic market halls and residential units. By midnight on April 22, firefighters had brought the fire under control, though hotspots remained active and required continued monitoring. The SSC confirmed via its official X account (@SSC_CDMX) that evacuation procedures were carried out in coordination with civil protection units, with shelters established for displaced vendors, and residents.
The incident occurred in a historically significant commercial zone known for its dense concentration of informal and semi-formal trade. La Merced, one of the largest traditional markets in Latin America, and the adjacent Sonora Market—famous for its herbal remedies, esoteric goods, and cultural artifacts—form a critical economic hub for thousands of daily workers. The fire disrupted livelihoods for many informal vendors who rely on these stalls for their income, with local advocacy groups beginning to assess losses and coordinate support efforts.
Authorities have launched an investigation into the cause of the fire, with initial assessments pointing to a possible electrical short or accidental ignition from cooking equipment in one of the food stalls. However, officials have not confirmed any definitive source, and the investigation remains ongoing. The Secretaría de Gestión Integral de Riesgos y Protección Civil (SGIRPC) of Mexico City has stated that it will review safety compliance in the area, particularly regarding electrical installations and the use of open flames in temporary structures.
As of the morning of April 22, 2026, cleanup and damage assessment operations were underway. Mexico City’s government has urged the public to avoid the area to allow emergency and municipal crews to work safely. Official updates are being issued through the SSC and SGIRPC channels, with further information expected regarding the status of affected vendors, potential reopening timelines, and any preventive measures to be implemented in the market zones.
This incident highlights ongoing safety concerns in Mexico City’s informal market sectors, where rapid urbanization, high vendor density, and limited infrastructure regulation often increase vulnerability to hazards such as fires. Similar incidents have occurred in past years in La Merced and surrounding areas, prompting repeated calls for improved safety standards, better access for emergency vehicles, and formalization of vendor spaces to reduce risks.
