Food Safety and Wildfires

Food Safety and Wildfires

Key Points- General
  • Wear appropriate personal protective equipment. Respiratory protection is important during a fire event and gloves and goggles are important during clean up efforts. 
  • Wash your hands and clothes after handling foods/items that were impacted by fire or smoke. 
  • Chemicals used to fight fires cannot be washed off foods and these foods should not be consumed.
  • If in doubt, throw it out! This goes for foods and any potentially hazardous materials (e.g., garden chemicals and sanitizers) that show signs of damage.


Key Points - Produce

*These recommendations are based on a report from UCCE Sonoma County entitled, "Produce Safety after Urban Wildfire: Citizen Science Initiative". These findings are based on gardens and produce not directly in the line of fire or adjacent to burnt structures that were impacted by smoke contaminants.

  • First, inspect produce for visible particle deposits and plant damage. If any damage is observed, discard these items and do not consume.

  • Washing produce with clean running water, remove outer leaves of leafy greens, and peel root vegetables prior to eating, cooking, preservation, or storage.

  • Test soil regularly to determine if and what level contaminants are present. This will serve as an indicator for potential produce contamination.

  • Produce can be soaked in a 10% white vinegar solution (by volume) to remove soil particles from produce (e.g., leafy greens).

  • Much is still unknown about produce safety following a wildfire event and more investigation is needed.
