The Ministry reported that it has instituted a surveillance programme, including additional testing, focussed on imported frozen berries.

The Ministry’s Director of Plants, Food and Environment, Peter Thomson, says the safety of consumers is MPI’s number one priority in taking the new measures. “Our investigations to date have not revealed a specific cause, but there is an association with consuming imported frozen berries. Recent outbreaks in other countries also suggest this link.

“We are giving a very high priority to instigating a testing programme that will provide increased surveillance of imported frozen berries. This will include previously imported stocks held by food companies here.

“In the meantime the general advice about food safety applies. People should wash their hands before eating and preparing food. Anyone who is concerned should briefly boil any frozen berries before eating them, or ensure cooking exceeds 85 degrees Celsius for one minute.  

“Elderly persons and those with chronic liver damage should avoid frozen berries that have not been heat treated. If you are concerned about a potential risk to your health, or the health of others, you should seek advice from your medical practitioner, or call the Ministry of Health’s Healthline (0800 611 116).

“If you are concerned about the safety of food products, contact the MPI consumer helpline (0800 008 333).”
