The author mainly worked on the detection of Salmonella presence identification and histamine level evaluation of yellowfin tuna (Thunnus albacares). A lot of factors caused the concentration of histamine and Salmonella to vary, depending on the fishing practices and storage conditions. Histamine analysis was done using the Veratox kit with the principle of ELISA method and it was found that no samples were found to surpass the maximum concentration allowed. Salmonella identification were done using the Nissui Compact Dry kit with colour as an indication (purple as negative and yellow/green as a positive result) and the result showed all negative presence of Salmonella in all the samples. Along with laboratory work, the author also learned and executed paper works for official legislation needs such as, log book analysis, supplier’s general evaluation, renewal of SOP legalization and also HACCP in the production line. In order to maintain the accuracy of the evaluations done in PT. Era Mandiri Cemerlang, an update of evaluation methodology technique and/ detection machine should be encouraged.
