A number of seed samples of CDC varieties were sampled in 2009 and 2010. These samples were tested at a small scale (5.7 g) in-house using the construct- and event-specific assays. Commercial laboratories using the construct-specific assay also tested these same samples. The commercial assay consisted of either a single or four independent 60 g subsamples. Results from the commercial tests were reported as either positive/negative for the subsamples as a whole, or positive/negative/trace for each subsample. As some four-subsample tests were reported as positive or negative, it is not possible to report the number of positive assays. The single positive in-house assay for CDC Mons was very weak and is reported as trace.
