why the worry wendy attitude? give it a break guys, before you chase the poor guy off.
pallet wood from overseas to the US is notorious for being treated for bugs (all the bugs get thru anyway)
the guy is from south africa, possibly using local pallets made out of local wood
my first set of kitchen cabinets were made from pallets, it was obviously all 1x12 pine shelving boards
the manufacturer of the units was from 40 miles away, i had no concerns then or now
