Advanced Instruments� new Fluorophos® Test System dramatically exceeds the U.S. Food and Drug Administration�s new pasteurization testing requirements and evaluates samples in 3 minutes.

Advanced Instruments’ new Fluorophos® Test System dramatically exceeds the U.S. Food and Drug Administration’s new pasteurization testing requirements and evaluates samples in 3 minutes.

As of March 1, 2005, dairy lab managers using the Scharer method of visual ALP colorimetric testing no longer comply with U.S. Food and Drug Administration pasteurization testing requirements. On that date, new ALP detection criteria of 350 mU (3 micrograms) per liter (0.075% raw milk equivalent) went into effect.

The new Fluorophos technology provides sensitivity to 0.003% raw milk and, unlike the colorimetric method, confirms the pasteurization of many different dairy products including bovine, sheep, and goat milk, flavored and cultured products, and cheeses. The cost per test is low and there is no need to run control samples with each test.

The Fluorophos test has been approved by the International Standards Organization, International Dairy Federation, Interstate Milk Shippers, and AOAC.

Fluorophos Testing Delivers Speed, Sensitivity, and Early Warning

Foremost Farms, formerly Wisconsin Dairies adopted the Fluorophos ALP testing system because of its speed, sensitivity, and because it didn’t require any hazardous chemicals that could endanger lab technicians. “The new ALP test is so sensitive it opens a window on what’s happening well below the 0.1% level,” said a company official. “It acts as a buffer. It buys us extra time to detect and correct problems.”

The Fluorophos test can be used to monitor and verify pasteurizer performance over time, giving plant managers an early warning and detection system to reduce unnecessary maintenance expenses. Sorrento Cheese of Buffalo, New York, experienced these benefits with the Fluorophos Test System. “The test is much more accurate than the standard Scharer Rapid phosphatase test and it produces results in three minutes,” said the company’s laboratory manager.

White Paper Available

A free, informative white paper reviews ALP testing options and explains their benefits to dairy process control and productivity. Titled “Pasteurization Testing in a Stricter Regulatory Environment,” the paper is available free – by download at Advanced Instruments’ web site at,or by calling, toll-free, 1-800-225-4034.

The new Fluorophos® Test System is on display at Advanced Instruments’ Booth #444 at the Food Safety Summit 2005, March 16-18 in Washington DC.
