AB SCIEX Responds to Milk Contamination Concerns with New Method to Detect
Easy-to-use method equips food & beverage testing laboratories around the
world for rapid response
FRAMINGHAM, Mass. -- February 11, 2013
AB SCIEX today announced the release of a new testing method for laboratories
to screen for and quantify dicyandiamide ‒ known as DCD ‒ in dairy products
and other protein-rich foods. Government regulators and food manufacturers
continue monitoring the milk supply globally, utilizing advanced analytical
technologies to help ensure food & beverage safety.
The new method from AB SCIEX to test for DCD is designed to increase the
accuracy and reduce the amount of time to identify dicyandiamide and other
nitrogen-rich compounds from hours to just minutes, with limits of
quantitation down to low µg/kg. AB SCIEX’s new method is an efficient and
highly sensitive method available for virtually any laboratory to use. Click

“AB SCIEX is a scientific resource for the food & beverage testing communities
around the world,” said Vincent Paez, Senior Director of Food & Environmental
at AB SCIEX. “We aim to equip scientists and lab technicians with easy-to-use
methods that can be implemented quickly and effectively used to prevent the
escalation of a food contamination crisis. Food testing laboratories are
always vigilant about the next contamination outbreak, and they require
technological tools from companies such as AB SCIEX.”
This new method is based on LC/MS/MS (liquid chromatography/tandem mass
spectrometry), an analytical technique that has become the industry standard
for improving food safety analysis. To achieve high levels of sensitivity and
selectivity for the most accurate results, AB SCIEX scientists used an
Eksigent ekspert™ ultraLC 100 System, a Phenomenex HPLC column and AB SCIEX
QTRAP^® 5500 technology, applying a simple extraction-dilution approach that
minimizes sample preparation and saves time and money.
This method is relevant in light of the recent news reports that trace amounts
of DCD, a fertilizer residue, were found in dairy products produced in New
Zealand. Responsible actions were taken across the industry last month to
avert a contamination crisis. As investigations continue, no evidence has been
reported about deliberate adulteration of dairy products; however, food safety
authorities are boosting surveillance of this contaminant to prevent
recurrence of any incidents and to alleviate the public’s concerns.
Preventative measures to enact further testing as a safety precaution are part
of standard policies and procedures for forward-thinking laboratory personnel.
AB SCIEX’s new method for DCD detection can be added to any food laboratory’s
method library to accelerate a rapid response.
DCD is reportedly used by farmers to reduce the negative effects of greenhouse
gas emission and nitrate leaching that can affect waterways. It has also been
reportedly used by some to promote the growth of pastures where cows graze.
Standards for the acceptance of DCD in food vary by country. While only small
trace amounts of DCD were detected in milk in the widely reported case out of
New Zealand recently, high doses of DCD are considered toxic for humans.
As a provider of next-generation food safety testing solutions, AB SCIEX has
been at the forefront of food contamination crises for the past decade. In
2007, AB SCIEX addressed the global crisis surrounding melamine and cyanuric
acid present in wheat gluten added to pet food, which resulted in the
fatalities of several cats and dogs. A year later, AB SCIEX’s method to test
for melamine was used to respond to evidence of tainted milk and baby formula.
