Combination sanitizer/soap mix like Betadine Scrub is preferred over straight
disinfection chemicals. It is a lot easier to get the boots clean if there is
some soap in the product.
Supplies leaving DHIA labs and offices need to
be free from contamination and may need to be sanitized on site as well.
Meter cleanliness will be checked at annual calibration. Meters in
violation of the policy will be cleaned and sanitized before being returned to
the field, with appropriate charge to the association. A report of any problem

interest in protecting their large investment. Effective Biosecurity requires
the cooperation of everyone working on or visiting the dairy.*
