    Special notes to users
  • If the MRL / EMRL of a specific food commodity is different from the MRL / EMRL of its relevant food subgroup or food group, the MRL / EMRL of the specific food commodity is applicable to that specific food commodity.

  • Interpretation:
    Processed Food and Compounded Food
  • Only food commodities specified in Schedule 1 to the Regulation will be included in the MRL Database. Majority of the MRLs/EMRLs stipulated in Schedule 1 to the Regulation are established for raw agricultural commodities of both plant and animal origins. However, where it is considered necessary for consumer protection and facilitation of trade, MRLs/EMRLs are also established for certain processed foods on a case-by-case basis, taking into consideration information on the effect of processing on the pesticide residues present in the food commodity. For a food in its processed form (other than compounded food), but not in a dried, dehydrated or concentrated form, unless there is a MRL/EMRL specified for the concerned “pesticide-food” pair in Schedule 1 to the Regulation, the MRL/EMRL specified for the corresponding primary food commodity or raw food ingredient applies. Users are advised to refer to the “Pesticide Residues in Food Regulation (Cap. 132CM) - User Guidelines” for details regarding interpretation of MRLs/EMRLs for processed foods.

  • Foods of Animal Origin
  • Where “(Fat)” displayed in MRL/EMRL of the search result, the corresponding MRL/EMRL applies only to the fat of the food (i.e., expressed on a fat basis).


  • Where “(F)” displayed in MRL/EMRL of the search result, the corresponding MRL/EMRL for milk products shall be determined as follows:

    (a) For a “milk product” with a fat content less than 2%, the MRL/EMRL applicable is half that specified for “milk”.

    (b) For a “milk product” with a fat content of 2% or more, the MRL/EMRL applicable is 25 times that specified for “milk”, expressed on a fat basis.
