—: no MRL value established for pesticide, where an MRL column contains no data, the particular data source either does not recognize this as an independent crop type, or no information is available. Usually, in this case, a “default value” is assigned corresponding to the limit of detection of the reference method (0.01–0.05 mg·kg−1) or another legislation is considered like EPA or EU. 0.05 and 0.1 mg·kg−1 correspond to the EU harmonized value. This implies that the EU member and nonmember states (Norway and Switzerland) recognize the harmonized level as the import tolerance. Where the nonmember states have a higher level as import tolerance, the value applied as MRL in both cases is 1 mg kg−1 [60].
