LAFD Opens 2 Shelters as Boyle Heights Warehouse Fire Spreads Smoke Across Los Angeles

Q: Beyond the smoke, what biohazard from 85 million pounds of rotting food now threatens Los Angeles?

Beyond the smoke, the main biohazard risk is the mass decomposition of roughly 85 million pounds of frozen food inside the burned Boyle Heights cold-storage warehouse. As that food thaws and rots, it can generate bacteria, mold, foul runoff, and decomposition gases, creating a major public-health and environmental threat if waste liquids or contaminated water escape the site. That is why Los Angeles officials are emphasizing continued air and water monitoring, not just smoke control. Ammonia was an early hazard because the facility used industrial refrigeration, and a suspected leak forced firefighters to pull back. But LAFD has said the ammonia tanks have been removed and that no additional toxic chemical threat beyond normal structure-fire smoke has been confirmed. The longer-term concern now is the spoiled food itself becoming a large-scale sanitation hazard. Experts generally worry in such cases about pathogen growth, odor, insect and vermin attraction, and polluted runoff entering storm drains or nearby waterways. The risk is heightened here because the warehouse is enormous, heavily damaged, and difficult to access, slowing removal and cleanup. So the threat “beyond the smoke” is not a newly identified airborne poison spreading across Los Angeles, but the biohazard created by millions of pounds of rotting food and the possibility that its decay products contaminate the surrounding environment.

Two shelters opened in Boyle Heights on June 20 as LAFD kept working the warehouse fire and smoke odor spread across most of Los Angeles.
Changing weather and ongoing suppression have made smoke more visible, with crews still attacking the fire from the roof and exterior and pouring large volumes of water into the structure.
A shelter-in-place order for zone 1279-A was lifted June 19, but a smoke advisory remains for zones 1239, 1241, 1279A, 1279B and 1281, with health officials urging residents to limit exposure.
The blaze began June 17 at a 1,000-by-500-foot cold-storage facility on South Los Palos Street, where a suspected ammonia leak forced firefighters from an offensive attack to a defensive posture.
