Abstract
    Indole concentrations of 114 samples of tropical shrimp, 3 samples of crayfish, and 3 samples of cold water crustaceans were determined. Cold water crustaceans contained less than 15 µg/kg indole, whereas crayfish contained between 62 and 123 µg indole/kg. In 81 samples (70 %) of tropical shrimp indole content was less than 50 µg/kg, but in 12 samples (11 %) indole content exceeded 250 µg/kg. Different batches of some products with high indole levels as well as of some products with low indole levels were analysed. Except for one sample high as well as low indole levels could be confirmed. Highest indole concentrations were determined in samples which origin was specified as South Pacific, Indo-Pacific, Malaysia, India and India/Vietnam.
