NORWOOD, MASSACHUSETTS, USA — February 4, 2014 — Joint work between the International Organization for Standardization (ISO) and the International Dairy Federation (IDF) has resulted in an important update to a key analytical standard for monitoring raw milk contamination in pasteurized dairy products, further reducing risks to public health. The International Standard for the determination of alkaline phosphatase activity in milk and milk products has been updated, reporting even greater precision in use of the fluorimetric testing method — as delivered by the Advanced Instruments’ Fluorophos® ALP Test System — and reconfirming the method as the International Pasteurization Test Standard.
“In 2006, the fluorimetric method received unanimous approval as a full International Standard method by the International Organization for Standardization (ISO), International Dairy Federation (IDF), and CEN European Standards Organization after having been intensively studied and investigated by experts internationally, and subjected to a series of trials. Since then, additional collaborative studies were undertaken by a joint ISO-IDF project group which proved that the fluorimetric method delivered even better precision. These findings resulted in the adoption of the new standard, ISO 11816-1|IDF 155-1, in November 2013,” explained Eileen Garry, project leader of the Joint ISO-IDF Project Group.
“The new ISO/IDF standard not only reconfirms the fluorimetric method as the EU Commission’s choice as the official EU reference method against which all other methods must be validated for use, but demonstrates even greater precision of the Fluorophos fluorimetric method for assessing the proper pasteurization of milk,” Garry said.
“Once again, the collaborative studies resulting in this International Standard update have determined that the Advanced Instruments Fluorophos ALP Test System is the method of choice for confirming pasteurization, with its superior sensitivity and precision,” she stated.
The Fluorophos ALP Test System employs a fluorimetric assay for the measurement of Alkaline Phosphatase levels in milk and other dairy products. The Fluorophos ALP Test System is extremely precise and rapid, with test results available in just 3 minutes; extremely sensitive, detecting as little as 0.003% raw milk contamination; and is HACCP ready for use with a Hazard Analysis & Critical Control Points programs. The System is certified globally with approvals by AOAC, ISO/IDF and FDA/NCIMS for confirming proper pasteurization.
The new standard, ISO 11816-1:2013 (IDF 155-1), Milk and milk products — Determination of alkaline phosphatase activity — Part 1: Fluorimetric method for milk and milk-based drinks, was published November 1, 2013. It specifies a fluorimetric method for the determination of alkaline phosphatase (ALP, EC 188.8.131.52) activity in raw and heat-treated whole milk, semi-skimmed milk, skimmed milk and flavoured milks. This method is applicable to milk and milk-based drinks from cows, sheep and goats. It is also applicable to milk powder after reconstitution. The instrument can read activities up to 7,000 milliunits per litre (mU/l). If the activity is higher than 7,000 mU/l, it is diluted with alkaline phosphatase-free milk so as to obtain a measurement not higher than 7,000 mU/l.
