Norovirus has been detected in mussels in some parts of Hawke Bay, meaning they are not safe to eat.

As a precaution, we advise the public not to collect filter-feeding shellfish, such as mussels and cockles, from the Bay until further notice.

Testing has been carried out in conjunction with Hastings District Council, Hawke’s Bay Regional Council, Health New Zealand | Te Whatu Ora, and New Zealand Food Safety.

If you are unsure if norovirus is present in an area where you collect shellfish, it is important to cook the shellfish thoroughly before it is eaten to lower the risk of getting sick.

Guidelines from New Zealand Food Safety state:

Shellfish you collect must be cooked thoroughly. Internal temperature must reach 90°C for 90 seconds to kill the virus. Boil shellfish for 5 minutes (3 minutes if shelled). Lighter cooking, such as steaming or cooking just until shells open, may not kill the virus, and will not ensure that the food is safe to eat.

There is a lot of helpful information on MPI’s website: Food safety when fishing and gathering shellfish | NZ Government (mpi.govt.nz)

Health New Zealand | Te Whatu Ora National Public Health Service Medical Officer of Health Dr Simon Baker says gastroenteritis (such as vomiting and diarrhoea) is a common side effect when consuming food where norovirus is present.

Anyone who develops illness or is concerned for their health after consuming shellfish should phone Healthline for advice on 0800 61 11 16.
