BAM #18 test for wood pallets

One of our readers (a wood pallet manufacturer on the east coast) called to say that one of his customers is requesting that he perform a BAM #18 test on outbound pallets. See link below.

http://www.fda.gov/F...BAM/default.htm

The manufacturer currently heat treats pallets, but because the HT process wicks moisture to the surface of the heated wood, mold can subsequently develop. The pallet is not involved in direct food contact, but presumably enters the processing area.

The manufacturer has no experience in such testing. Any thoughts appreciated with respect to:

1. How should they proceed vis a vis testing requirement?
2. Is such a requirement unique to this customer, or is it something that is practiced more widely and may constitute an emerging trend?

Thanks
