The frozen berries recalled this month are understood to have been from the same shipment of fruit from China that caused the 2015 hepatitis A outbreak.

Fairfax Media can reveal that health authorities suspect the berries at the centre of the February 2015 and June 2017 recalls were produced at the same place in China around the same time.

"We understand the batch of frozen berries at the centre of this [current] recall [was] sourced from the same plant and area in China at around the same time as the berries responsible for the 2015 recall," a spokesman from the Department of Health and Human Services in Victoria said.

Its tests revealed the hepatitis A detected in the recalled Creative Gourmet mixed berries 300 gram packs has an identical sequence to the strain found in the Nanna's and Creative Gourmet packs recalled in 2015.
