Another problem with wintertime toxicity data is that toxin levels are reported per 100 gm of tissue. Studies of the deep sea scallop Placopecten magellanicus indicate that the size of the digestive gland can vary through the year (51). Thus a constant amount of toxin in a gland would look variable when normalized to 100 gm of tissue, with the highest relative toxicity during winter months when the tissues are the smallest. It would appear, however, that this error is small (perhaps 20-30%) relative to the 2 to 4-fold toxin increases typically reported between seasons in scallops (4, 47).

The arsenobetaine 54 and riboside 56 as the major water-soluble arsenic compounds were characterized in the sea scallops (Plactopecten magellanicus) and Icelandic scallops Chlamys islandicd) collected near Newfoundland [161]. This result indicated that consumption of the scallops poses little human risk.

The CLA content of fish and marine products is negligible. Fritsche and Steinhart (12) reported that the CLA content of 9 species of fish, purchased from local shops, ranged from 0.1 to 0.9 mg/g fat. Chin et al. (10) found the mean CLA content of 2-A samples of salmon, lake trout, sea scallop, shrimp, and mussels was 0.3, 0.5, 0.3, 0.6, and 0.4 mg/g fat, respectively.
