According to European Union (EU) rules, foods containing less than 0.9%
genetically modified (GM) ingredients need not be labeled as containing GM,
provided that this presence is ?adventitious or technically unavoidable
during seed production, cultivation, harvest, transport, or processing?,
January 2006

In relation to this, Tristan Funk of Technische Universität, München,
Germany and colleagues look at ?Outcrossing frequencies and distribution of
transgenic oilseed rape (Brassica napus L.) in the nearest neighbourhood.?
Their research, published in the January 2006 of the European Journal of
Agronomy, focused on the possibility of GM canola outcrossing into nearby
non-GM plants, and arose out of work on a two-year field trial.

By checking on the resistance of plants in surrounding acceptor plots,
researchers found, among others, that 1) an average gene flow of 0.28%,
0.01%, and 0.0065% was detected for 100%, 1.0%, and 0.1% transgenic donor
plots, respectively, clearly below the EU labeling threshold of 0.9%; 2)
outcrossing events in short distances are mainly due to insects, such as
honey bees and wild bumblebees; 3) a separation distance as low as 1.1m
would already be sufficient to comply with the EU threshold.
