Maximum levels of THC in food

The Ministerial Decree of 4 November 2019 (OJ No 11 of 15-1-2020) defines maximum levels of THC (Tetrahydrocannabinol) in foods derived from hemp. The Decree lays down the values of the maximum concentrations (maximum limits) of total THC in food for the purposes of official control.

Foods derived from hemp are defined in Annex I of the Decree and are:

– seeds

– flour obtained from seeds

– oil obtained from seeds

The maximum limits of total THC in food are shown in the table (Annex III of the decree).

THC (tetrahydrocannabinol) total means the concentration resulting from the sum of the concentrations of the substance «Δ9-THC ( (-)-trans- Δ9-THC» and the non-active acid precursor «Δ9-THCA-A (delta9tetrahydrocannabinolic acid A)».



Sampling of food must be carried out in accordance with the basic rules laid down in Regulation (EC) No 401/2066 in order to obtain a representative homogenous laboratory sample. Sampling must be carried out in accordance with the basic rules laid down in Regulation (EC) No 401/2066.
