Dear Listservers
Some comments relating to the original message from Adam Simpson; there is
another message about ammonia and TMA contents of fish and the detection of
these two amines.
I go along with other correspondents that high ammonia contents in fish, to
the extent that they are pungent, would point to elasmobranch fish being
involved. In response to Visage's message of 17 May, my experience is that
the smell of ammonia and TMA does not linger after the source is removed. If
the container is designed for the carriage of foods, and in good condition,
all joints will be well sealed and waterproof. Otherwise the container
should not have been used for carrying fish, frozen or not. The container
should be cleaned in the same way as any other heavily soiled food
equipment - pressure washing using a heavy duty detergent, followed by
rinsing with clean water. There is no requirement for acidic chemicals to be
used.
