"This has been a devastating blow to us all."
Last night Mr Glover told NZME he was "devastated" by the news his berries were the source of the Hepatitis A contamination, which has seen four people struck down with the disease.
"We're obviously devastated that a product we have sold to our loyal customers has been found to have traces of Hepatitis A," he said.
His Nelson-based firm had been importing from the Shandong-based suppliers for seven years.
MPI spokesman Peter Thomson said the department had so far identified four cases of Hepatitis A linked to the frozen berries, and said it was "entirely possible" more people could fall ill.
The Ministry has not been able to rule out the possibility of further recalls, he told Radio New Zealand.
"I don't have dates and timelines for when the product entered the country... that's where our investigation continues across the entire supply chain," he told the broadcaster.
"We've got a lot of product coming into the country not just with this company, but we're continuing to investigate and if we get more information confirming a risk to the public we'll be issuing other recalls.
"We just need to keep working the problem and examining the data and collecting more data on the supply chain until we're satisfied that we've run the leads down sufficiently. But this is all about safety of consumers, so if we do get any further concerns then we'll be letting people know."
The four people who were infected with Hepatitis A sought medical help during the period between late October to mid-November, Mr Thomson said.
"But of course the onset of the disease, the symptoms can take quite a long time, between 15 and 50 days, which is part of the reason why this has been a difficult investigation as we try to get people to recall what they have eaten over that extended period of time."
Frozen berries had a shelf life of up to three years, Mr Thomson said, so the contaminated batch could have come at any point over that time. However, he said with the volumes of frozen berries coming into the country, it's likely they would "move through the system fairly well".
"We don't know the extent of any contamination event that might have occurred during the supply chain... and that's why we can't just conclude that we've got everything."
