Roundup and other glyphosate-based products aren’t only used on farms. In a coastal-suburban community like San Juan Capistrano, exposure often shows up in familiar settings, for example:
- Home and yard maintenance: mixing concentrate, spraying around patios/walkways, or mowing treated areas shortly after application.
- Landscaping and grounds work: property maintenance, HOA landscaping, or seasonal weed control for shopping centers and office parks.
- Secondhand exposure: residue brought home on work gloves, shoes, or clothing, especially when protective gear isn’t used consistently.
- Nearby spraying and drift: living or working near properties where herbicides are applied on a schedule.
Because these scenarios are common, the legal question usually isn’t whether a chemical was “in the world”—it’s whether the product was used/present in a way that can be connected to your illness with credible evidence.
