Ladas Foods S.A. has established a purchase policy for olives, preferably from growers who are registered in the Integrated Management & Operation System, and can testify to the rational use of active substances as well as the permitted time period of their application. Certainly, when it comes to growers who are not registered in the I.M.O. system, the purchase of olives takes place only when the analyzed samples meet the permissible limits of active substances. Otherwise the olives are rejected.
