Detection of Testosterone hormone and 17-Methyltestosterone residues in some fish products at retailed market

Abstract

This study was done to estimate the testosterone and 17-methyl-testosterone residues in 45 samples of fish burger, fish kofta and fish fingers. Samples were collected randomly from different localities at Cairo retailed markets and were analyzed using Emzyme-Linked Immuno Sorbent Assay (ELISA) method. The mean values of testosterone residues in fish burger, fish kofta and fish fingers were 0.41±0.21µg/kg 0.11 ± 0.04 µg/kg and 0.62±0.24µg /kg respectively. While, the mean value of 17-methyltestosterone were 0.81 ± 0.03 µg/kg, 0.94 ± 0.19 µg/kg and 1.01 ± 0.16 µg/kg, respectively. The obtained values were found to be within the acceptable daily intake. So, it seems that the present status of this hormones in marketed fish products does not cause any public health hazard but required a routinely monitor of such chemicals as a food quality control measurement.
