Fish is a source of high-quality protein. Protein in fish has a complete composition and amount of essential amino acids. However, fish is a type of food that is susceptible to biological damage and is susceptible to microbial contamination so that it quickly decays. One of the most important microorganisms in spoilage of fish meat is Escherichia coli bacteria. This study aims to determine the presence of Escherichia coli bacteria in scad, tuna and skipjack tuna.
