Safer water use from field to market

How water source, timing, contact with edible crops, cleaning, and simple records affect food safety and crop quality.

01

Know the source and exposure

Water risk depends on its source, storage, treatment, distribution, timing, and how it contacts the edible part of a crop. Protect wells and tanks from runoff, animals, waste, and damaged covers. Inspect irrigation lines and storage containers regularly. A clear-looking source is not proof that water is microbiologically or chemically safe, so testing and local public-health or agricultural guidance may be necessary.

02

Prevent contamination during handling

Use clean hands, containers, knives, tables, and packing areas. Prevent dirty field crates from becoming wash containers. Keep livestock, manure, wastewater, and chemicals away from harvest and packing zones. Washing cannot reliably correct every upstream contamination problem, and using contaminated water may add risk rather than remove it.

03

Respond when water safety is uncertain

After flooding, sewage exposure, chemical spills, unusual odour, dead animals near a source, or a public warning, stop and assess before using the water or selling affected produce. Separate potentially affected lots, record dates and fields, and contact the appropriate local authority or qualified professional. Do not market food as safe based only on appearance, smell, or taste.
