In said procedure, following placement of the agricultural food product in
a bag, the following stages are carried out: a) the CO.sub.2 and O.sub.2
are mixed, with the concentration of CO.sub.2 equal to or higher than 40%
and the concentration of O.sub.2 equal to or lower than 5%; b) the bag is
filled with the mixture resulting from stage (a) by teans of a scavenging
operation or the creation of a vacuum inside the bag, setting up a
pressure of 350 mbar inside the bag; c) the agricultural food product is
exposed to the mixture of gases for a time that ranges between 4 and 26
days, the concentration of CO.sub.2 falling to 30% and the concentration
of O.sub.2 rising to 9%; said procedure permitting the eradication of
insects and/or mites at any stage of their development.
