As a precaution, please adopt the following decontamination protocols regardless of where you are surveying/gathering materials.
If possible, only visit one field location per visit. Never go from one site to another site without cleaning your hands, shoes, tools, and vehicle.
Check that vehicle has been decontaminated including inside mats, tires and underside of vehicle before entering. Use alcohol wipes or sprays as on commonly touched areas.
Decontaminate hands and equipment before and after you survey/collect samples. To reduce the risk of moving spores from one tree to another, sanitize hands and tools after each tree.
When entering coffee farms, please keep in mind quarantine measures on infected and non-infected fields. If possible, meet farmer at gate to get materials or park outside of property away from coffee trees and enter field on foot.
After exiting vehicle, put on protective clothing (disposable or sterile coveralls).
Clean shoes or boots with a brush to remove debris and spray with 70% alcohol or dip in freshly prepared 10% bleach prior to entering field. A sanitizing footbath/mat can be used with a disinfectant. Or change shoes when entering and exiting vehicle, store shoes in a plastic bag, and disinfect shoes at office.
A freshly prepared 10% solution of chlorine bleach and water can be used on tools as long as tools are oiled afterwards, as chlorine bleach will corrode metal tools.
When leaving field: remove coverall and place in plastic bag and seal. Disinfect shoes with ethanol or bleach solution.
Vehicles used in infected areas should be thoroughly cleaned; run vehicle through car wash and include underside wash when returning from field and before returning to office. If the carwash is closed or unavailable, power wash field vehicle on gravel.
Disinfect equipment and tools and store in clean area.
Field clothing should be machine washed with detergent in hot water and dried under high heat. Disposable coveralls should be autoclaved prior to disposal.
Please be careful when using alcohol and bleach and follow all label precautions to prevent damage to your eyes, skin, respiratory system, clothing, and equipment. Correctly label spray bottles with a Sharpie pen and take bottles with you in any field vehicle for use before and after all field activities. Store bottles in the vehicle in such a manner that they do not spill.
