New Zealand finds botulism signs in milk products

New Zealand dairy giant Fonterra announced on Saturday that tests of some ingredients used in infant formula and sports drinks have turned up a type of bacteria that could cause botulism, and customers were urgently checking their supply chains.

The company is the world’s fourth-largest dairy company, with annual revenues of about US$16 billion (HK124 billion).

The news comes as a blow to New Zealand’s dairy industry, which powers the country’s economy. New Zealand exports about 95 per cent of its milk.

Consumers in China and elsewhere are willing to pay a big premium for New Zealand infant formula because the country has a clean and healthy reputation. Chinese consumers have a special interest after tainted local milk formula killed six babies in 2008.

The Centers for Disease Control describes botulism as a rare but sometimes fatal paralytic illness caused by a nerve toxin.

Fonterra said it has told eight of its customers of the problem, which dates back more than a year, and they were investigating whether any of the affected product is in their supply chains. Fonterra said those companies will initiate any consumer product recalls.

At a news conference Saturday, Fonterra repeatedly refused to divulge the companies, countries or specific products affected. Gary Romano, the managing director of Fonterra’s New Zealand milk products, said his company supplies raw materials to the eight companies and it is up to them to inform their consumers of what products might be tainted.

The company did acknowledge its chief executive, Theo Spierings, planned to fly to China in Saturday, in part to deal with the fallout from the botulism scare.

Romano said the problem was caused by unsterilized pipes at a Waikato factory. He said three batches of whey protein weighing about 42 tons were tainted in May last year, adding that Fonterra has since cleaned the pipes.

The company said in a release it identified a potential quality problem in March when a product tested positive for the bacteria Clostridium. Many strains of the bacteria are harmless, the company said, and product samples were put through intensive testing over the following months. It said that on July 31 it discovered the presence of a strain of the bacteria that can cause botulism.

Romano said Fonterra hasn’t received reports of anybody getting sick and added that the problem hasn’t affected any fresh milk, yoghurt, cheese or long-lasting heat-treated milk.

New Zealand’s Ministry for Primary Industries said it was working with the company to investigate.

Spierings, the chief executive, said in the release that food safety was the company’s top priority.

“We are acting quickly,” he said. “Our focus is to get information out about potentially affected product as fast as possible so that it can be taken off supermarket shelves and, where it has already been purchased, can be returned.”

Rabobank’s last year Global Dairy Top 20 report ranked Fonterra as the world’s fourth-largest dairy company by revenue behind Nestli, Danone and Lactalis. The company is a cooperative, partially owned by thousands of farmers.

In 2011 the company collected 15.4 billion litres of milk in New Zealand, representing about 90 per cent of the country’s total.

In 2008, six babies in China died and another 300,000 were sickened by infant formula that was tainted with melamine, an industrial chemical added to watered-down milk to fool tests for protein levels.
