Why conventional disinfestation processes are problematic!
Abstract: Until now, the most common treatment against storage pests has been to use toxic
insecticides or toxic gases such as methyl bromide, phosphine or hydrocyanic acid. The
available analysis methods can detect even the smallest trace residues of these plant protection products. The problem of residues is exacerbated in the case of products which are already compromised, e. g., due to improper disinfestation in their origin country during cultivation, or as a result of soil and environmental pollution in the areas where they are grown. The modern, well-informed and health-conscious consumer will no longer tolerate any kind of residues harmful to health. In addition, handling with toxic products is more dangerous and needs more financial effort to fulfil the requirements of environmental protection and work safety than using a natural and nontoxic plant protection product like CO2. Pest control with CO2 is applied to grains, cereals, dried fruits, dried vegetables, confectionery, nuts, tea, cocoa, coffee, tobacco, medicinal plants and rice which are infected by adult storage insects as well as by their larvae or eggs. This process is now established for over 30 years in several countries.
