risk
The Ministry for Primary Industries (MPI) is
warning people not to eat a number of brands of chilled
oysters harvested from the Mahurangi Harbour north of
Auckland as they may be contaminated with norovirus.
The companies Matakana Oysters Limited, Orata Marine Limited, Seafood Harbour and Hutchings and Addison Limited are recalling all oysters harvested from the Mahurangi Harbour from mid-January 2017. All companies are cooperating with MPI in managing this issue.
Batch numbers and brand names are not fully confirmed as yet, but further detail will be posted on MPI’s website as it becomes available.
The products are not exported. Most are sold in the local area in pottles or on the half shell.
MPI’s Manager of Food Compliance Service Group, Melinda Sando, says the amount of affected product out there is likely to be very small as these products have a very short shelf life.
“Our main concern, however, is that people may have frozen the oysters and still have them in their freezer. It is very important that they are discarded.”
MPI has also put a halt on all harvesting of oysters from the harbour, which is near Warkworth north of Auckland.
Ms Sando says the Ministry was alerted to the issue by local health authorities after 11 people became ill after eating oysters from the area.
“Samples of the oysters were tested by ESR and norovirus was found. The type of virus is the same as that found in the affected people.”
Norovirus gastroenteritis generally presents with
vomiting followed by diarrhoea. The Ministry advises people
who believe they have eaten affected oysters to see their GP
if symptoms are severe or persistent or if they are unable
to keep hydrated.
Information is also available through
the Ministry of Health’s Helpline 0800 611 116.
Ms Sando says the problem appears to be limited to a small area of the harbour around Dyers Creek.
“It is likely to be the result of a localised contamination – for example discharge from a boat or a leaking septic tank.”
MPI is continuing to investigate.
