There were a number of labelling offences taken up with importers and
producers. Two consignments of frozen cooked prawns were detained and returned
to the Malaysian producers due to excessive bacterial plate counts.
Much of the imported foodstuffs is by direct or indirect importation in
containers. The associated problems are now gradually being ironed out, but
there will always be a weakness in the examination system at point of entry
as an incident in the area shows
A consignment of prepared meat in gravy from an approved source was
brought in a "cleared" container to a distrubution warehouse and on "unstuffing"
many cartons were found to contain blown cans. The Food Inspector investigated

cause blowing this would have been disastrous as the cans were of catering
size for use on re-heating as pie filling, The Port of Entry and the Veterinary
Office of the country's representatives in London were immediately informed
and all consignments carefully examined with an investigation into slaughtering
and processing method at the canning factory.
