Presencia de verde malaquita y leucoverde malaquita en especies bioacuáticas y productos de uso acuícola.
In aquaculture are used various drugs and chemicals for veterinary use to prevent or treat diseases, control pests, help production processes and promote growth. These substences are usually incorporated in the so-called feed. Hence, the unregulated use of ingredientes in different formulations as preservatives and dyes may also cause a risk in food safety. The National Fisheries Institute monitor the waste coming from drugs, to comply with international market requirements in relation to quality standards. Residues of Malachite Green (MV) and Malachite Leucoverde (LMV) were in 82 samples of fish meal, shrimp and squid, balanced, nutritional substances in different forms granules, pastes and powders, vitamins, desinfectants, fungicides and medicated liquids and exercising same effect as part of the checks carried out under the Testing Laboratory of Aquaculture Products running on these products prior to the extension of sanitary registration certificate for Official Control and also at the request of PrivateEnterprise. This research also outlines important aspects related to waste dyes tilapia and shrimp farming and procesing, fish meal balanced development and analytical method used for quantification, in the period from January to August 2010. The developed method has been validated in the matrix specified curves obtained with a goodfit of a straight for both analytes, with correlation coefficients R2~.0,99, limits of detection of 0,25 ppb for shrimp and tilapia and 0.50 ppb for fish meal and balanced well aspercentages of recovery ranging between 90 and 100% and satisfactory results in interlaboratory tests. The results showed thet not have been detected in VM and LVM. The samples analyzed registered values below the limit of quantification of the method (0,25 and 0,50 ppb for VM and LVM respectively), which confirms the limited use of these substances in our country.
