Agriculture, Weights & Measures
If you've ever been to a farmers’ market, checked out at a
grocery store, pumped gas, or wondered if your produce was organic,
then you've benefitted from the Department of Agriculture, Weights
& Measures (AWM).
As part of the County’s Land Use & Environment Group, we're here to serve you.
What AWM does for you:
- Ensures pesticides are used safely and investigates related illness.
- Prevents the spread of pests that harm agriculture and the environment.
- Promotes the use of natural pest controls.
- Verifies produce that is marked as organic.
- Ensures vendors at farmers' markets grow what they sell.
- Verifies that commercial weighing and measuring devices and price scanners are accurate.
- Protects people from injury
and disease caused by wildlife.
