This research aims to determine the best concentration of Rusip fermentation solution for inhibiting histamine formation and its effect on the quality of salted-boiled mackerel tuna (Euthynnus affinis). The studies were conducted in August-September 2018 at the Fisheries Product Processing Laboratory and Microbiology and Molecular Biotechnology Laboratory of Fisheries and Marine Sciences Faculty, Padjadjaran University. This work used an experimental method with 4 variables and 3 repetitions, namely salted-boiled mackerel tuna (Euthynnus affinis) that soaked in rusip fermentation solution with a concentration of 0%, 10%, 20%, and 30% for 30 minutes and storage at some above room temperature (25-27 ºC). Parameters observed included TPC, Histamine levels, pH, and organoleptic values (aroma, appearance, and texture). The result showed that the use of 30% rusip fermentation solution was able to inhibit the formation of histamine and produced the lowest histamine levels of 29.80 mg/100 g. The number of histamine-forming bacteria is positively correlated with histamine content during storage. Based on the organoleptic value (aroma, appearance, and texture), the use of 30% rusip fermentation solution was still received by panelists and fulfilled the best quality requirements according to SNI 2717-1-2009 until the fifth day of storage compared to the other treatments.

Scombroid fish or histamine food poisoning is an illness typically associated with fish consumption, rarely encountered and reported in Europe. Symptoms develop quickly and resemble an allergic reaction. This paper reports three cases of severe scombroid poisoning in previously healthy patients, which presented diffuse macular erythema, hypotension, palpitations, and abnormal electrocardiogram (ECG). All patients required intensive care, with a complete resolution of symptoms and ECG changes within 24 hours. This is the first Romanian report of scombroid poisoning, emphasizing that medical personnel should be aware of this condition, because symptoms and ECG changes often lead to confusion with other diseases.
