The science regarding allergens being present in agricultural chemicals and then remaining on the product is not well documented at this time. The CanadaGAP program requires only that operations show their due diligence by recording information for allergens on Form S. Beyond that, the program does not require that these agricultural chemicals not be used. This may change in the future if the science shows there is a need to. So, for now operations need to fill out Form S (Column I – present in production practice) and have the information documented. This also means that declaring these allergens on the product/packaging label is not required at this time.
