White shrimp (Penaeus setiferus) were held at 0, 10, 20, 30, 37, and 44 C for 3, 6, and 24 h. Serious quality deterioration, as evidenced by off-color development (red and orange pigmentation) and off-odor development, was beginning to occur in shrimp held for 3 h at 30, 37, and 44 C, for 6 h at 20 C and for 24 h at 10 C. Red color development was evident in shrimp held at 30 and 37 C, orange color in those held at 44 C. Putrid odors appeared more rapidly in shrimp held at 37 than at 44 C where shrimp developed cooked-shrimp odors. Large increases in bacterial counts at 30–44 C (after 6 and 24 h) were usually accompanied by putrid odors. Tissue pH changes were erratic and small. Total volatile nitrogen (TVN), free amino acid nitrogen (AA-N), and urea production increased with storage temperature during the 3- and 6-h storage experiments. Musty and cooked-shrimp off-odors developed in the shrimp as a result of chemical and/or enzymic activity while putrid and sour odors were produced by bacteria growing in the shrimp.

Aerobic plate counts of fresh pond-reared shrimp (Penaeus stylirostris, Penaeus vannamei, and Penaeus setiferus) ranged from 1.5 × 103 to 1.3 × 104 per gram. Coryneform bacteria and Vibrio spp. dominated the microbial flora of shrimp. Aerobic plate counts of pond waters ranged from 6.1 × 102 to 2.2 × 104 per milliliter. Vibrio spp. usually were dominant in pond waters. Enterococci and coliform levels in shrimp were low. Fecal coliforms were present in only one of 11 shrimp samples. No Escherichia coli was recovered from pond-reared shrimp. Salmonella, Vibrio parahaemolyticus, Bacillus cereus, and Clostridium perfringens were not recovered from either shrimp or pond waters. No relationship could be established between changes in numbers and types of microorganisms in pond-reared shrimp or pond waters and changes in characteristics of the pond waters such as temperature, salinity, dissolved oxygen, and pH.
