–Upon receipt of a notification from the Macau authorities earlier that a batch of smoked salmon imported from Hong Kong was contaminated with Listeria monocytogenes, the CFS, for the sake of prudence, has immediately instructed the manufacturer concerned, Polyfood Food Service Co Ltd, to recall all affected batches of the product. The Centre has been proactively following up on the incident in the past few days and has taken food and environmental samples for testing. Notification received yesterday stated that Listeria monocytogenes was detected in a smoked salmon sample.
–Listeria monocytogenes can be easily destroyed by cooking but can survive and multiply at refrigerator temperatures. Most healthy individuals do not develop symptoms or only have mild symptoms like fever, muscle pain, headache, nausea, vomiting or diarrhoea when infected. However, severe complications such as septicemia, meningitis or even death may occur in newborns, the elderly and those with a weaker immune system. Although infected pregnant women may just experience mild symptoms generally, the infection of Listeria monocytogenes may cause miscarriage, infant death, preterm birth, or severe infection in the newborns.
