Who checks all the plots to know if they are certainly organic? Who investigates to guarantee that nobody is cheating? With the agreement of certifying agencies APPTA has developed an Internal Control System, which allows the producers to check among themselves.

Normally when there is a certified producer, the agency sends an inspector to check the property and prepare a report with a simple map of the property and quantitative and qualitative information of the property. When there is not only one producer, but more than one thousand producers the matter is not so simple for the Certifiying Agency.

By applying the method of "Certification of Organized Groups", APPTA has trained a group of 17 Talamancan internal inspectors, that is to say, they visit all of the producers, collect information, observe whether the producers are not violating the regulations, and then make a report on each property that is visited.

This information is sorted and filed in the database of APPTA. In such a way the Certification Agency can come and check the file of producers at any time, and it can also go to the field to visit a percentage of the producers (e.g. it can decide to visit 10 or 20% of APPTA's 1100 certified producers). This Alliance and work is possible thanks to the capacity of APPTA's inspectors, and to the integrity of all the producers.
