The objective of this study was to evaluate the effect of cell-free supernatant (CFS) from <i>Aeromonas sobria</i> on the growth and spoilage potential of <i>Shewanella putrefaciens</i> in Pacific white shrimp (<i>Litopenaeus vannamei</i>) during cold chain logistics, including transportation, retailing, and domestic storage. It was shown that the quality of shrimps deteriorated in the cold chain logistics over time. The temperature fluctuation during the experimental period favored the growth of <i>S. putrefaciens</i>, increased the total volatile basic nitrogen (TVB-N) and biogenic amine value, and decreased the sensory quality of shrimps. The application of CFS resulted in the decline on the growth of <i>S. putrefaciens</i> after the early stationary phase stored at a cold condition. It is concluded that the application of CFS can inhibit microbial growth and the spoilage potential of <i>S. putrefaciens</i> and offset the quality deterioration of shrimp exposed to temperature fluctuation during cold chain logistics.
