Measures that reduce the vulnerability or susceptibility of the commodity (host or carrier) to pest infestation.
Host or carrier
Summary
Trade is restricted to commodities that are not hosts (or carriers), or that are modified to make them less vulnerable to infestation.
Trade can be restricted to those varieties or cultivars that are a non-host or poor host for the pest. In some cases, the export standard commodity may be harvested at a developmental stage that is a non-host or poor host for the pest. Quality specifications and prohibit parts of commodity measures can ensure that commodity units or parts thereof, respectively, that are more likely to be infested are excluded. And the vulnerability of the commodity to infestation can also be modified physically or chemically.
Host status is a key consideration when conducting pest risk analysis. Measures that affect the host or carrier can be considered during risk assessment or be applied as phytosanitary measures.
Additional measures are not required if the commodity is a non-host. Measures that result in poor host status may be incorporated into a phytosanitary systems approach.
