Cultured blue shrimp (Penaeus stylirostris) were treated with normal therapeutic amounts of formalin (50 and 150 ppm) for 6 or 24 h. Analyses for extractable formaldehyde residues were run on the tails from these shrimp immediately after death and after storage at ambient (24°C) and refrigerated temperatures. No formaldehyde residues in these shrimp were found to result from the therapeutic use of formalin. However, shrimp tail muscle was found to produce small amounts (up to 4.8 ppm) of extractable formaldehyde during postmortem decomposition.
