Comparison of GM Contamination Register with the EC RASFF database by country, for all years 1997–2013. EC RASFF database records notifications for each incident, including those relating to a single GM line in the same country and year. In the GM Contamination Register, these are recorded as a single incident, resulting is a lower total no. of incidents for each RASFF country. This prevents a skew of the data towards RASFF countries and the reportage of repeated incidents.
