Warnings over the risk of Hepatitis A from imported frozen berries - after three people recently came down with the liver disease

NZ New Zealand Food Safety is advising consumers to consider extra precautions - especially the elderly and pregnant, and those with chronic liver damage.

Precautions include briefly boiling frozen berries before eating them, and washing their hands before eating and preparing food.

Hepatitis A is relatively rare in New Zealand, but in 2015 imported frozen berries were linked to an outbreak.
