Fonterra, New Zealand’s largest dairy manufacturer, last week issued a warning that Clostridium botulinum had been found in three batches of whey protein, (approximately 40 tonnes), which can be used to boost the protein content of many foods, including infant feeding formula.
The warning caused a New Zealand manufacturer of infant feeding formula to recall certain batches of product. Fonterra Chief Executive, Theo Spierings also flew to China to discuss the issue with Chinese food safety authorities.
Apparently, the source of the bacteria has been traced to a dirty pipe in a processing factory. If this is true, it’s a serious lapse in process control and obviously should not have occurred.
Food Standards Australia New Zealand is aware of the announcement by Fonterra regarding several batches of its whey protein concentrate possibly contaminated with Clostridium botulinum and subsequent recalls of two Nutricia products as a precautionary measure.
