A map of the property identifying any risk areas.
The location of old batteries, farm rubbish tips, old painted timbers, commercial painted surfaces, machinery and any potential chemical storage or disposal area. or land which shares a boundary with public land (eg. roadways. railways. state forest. national park) should be highlighted on the map.
This will ensure a livestock producer is doing all they can to prevent unacceptable levels of persistent chemicals and physical contaminants entering the meat they produce.
Physical contaminants are items such as broken needles, buckshot and wire which may work their way into the meat being produced.
Persistent chemicals break down very slowly. Areas contaminated with persistent chemicals may have to be managed for decades, depending on the chemical involved, climate and soil type. Lead, arsenic and cadmium do not breakdown, although their levels may reduce over time as a result of dilution or leaching.
