Cleaning of Clothing, Equipment and Supplies During Survey of
Commercial Potato Fields
On surveys of commercial potato fields, special cleaning must be
completed as follows before leaving one field and entering the next
field:
1. Each crew member must use a stiff bristle brush to clean all soil
from their trousers, shoes, and materials.
2. Thoroughly clean trowels used for sample collection. Trowels
must be free of recesses or grooves where soil may become
impacted.
3. Before leaving the survey property, clean mechanical sampling
equipment with hot water under pressure, using a single orifice
nozzle to remove all soil from the equipment. See Cleaning and
Disinfecting Equipment on page 2-2-19.
Cleaning and Disinfection for Survey of Seed Potato Fields
Personnel conducting survey on seed potato lands must take extra
sanitary precautions before entering, moving from one field to the
next, and exiting survey fields.
When the seed potato field survey is complete, clean your boots,
materials, and tools with a stiff bristle brush to remove all soil.
Disinfect boots, materials, and tools by scrubbing with a solution of
5.25 percent hypochlorite in 10 parts water before leaving one field
and continuing in another field.
