Considerations on the application of organic fertilization and food safety.

Abstract

The integration of the application of organic fertilization and safety for health from the point of view of food quality in the agro-industrial process, has been little studied in research and reported in scientific and non-scientific publications, which is currently becoming a problem for the health of our country and why not, for the world, due to the deficit and high costs of mineral fertilizers and the inappropriate use of water and residual products. The objective of this work is to expose the results of investigations carried out with swine residuals and sediments from reservoirs with vegetable crops under organoponic conditions, demonstrating the effectiveness and safety of these two residuals, used as a substrate in organoponic, to which chemical and microbiological analyzes were carried out to verify their use as organic fertilizers. The organic residuals from pig farms are rich in organic matter and appreciable amounts of mineral elements (N, P, K, Ca and Mg). The sediments have to be combined with organic fertilizers due to their low nutrient content compared to pig residuals. These results are of great importance from the social, environmental and safety point of view, risk reduction and prevention of food borne diseases, due to the positive effect of effluents and sediments in terms of soil preservation, its use as an organic substrate, and its safety due to the absence of pathogenic organisms.
