New Laboratory Instrument Acquisition - UHPLC
A new ultra high pressure liquid chromatography
(UHPLC) instrument was added in Office of the Tex-
as State Chemist (OTSC) to augment the current ca-
pacity of the Agriculture Analytical Service (AAS). A
method for analyzing aflatoxin has been validated on
the new instrument to prepare for the 2014 corn har-
vest. Compared to the old HPLC method, the new
method shortened the analysis time to one third, re-
duced the chemical consumption three fold thus
providing a more efficient and economical analysis.
The UHPLC will allow the lab to further increase an-
alytical capacity and capability.International Journal of Regulatory Science
Advancing the science of creating tools, standards and practices to im-
prove the protection and compliance of food systems is the focus of a
new graduate curriculum and journal focusing on regulatory science.
The second volume of the IJRS focuses on the role of standardization
in regulatory science.
Regulators and industry use standards to achieve uniformity in the feed
and food industry and provide a tool to measure conformance. Often
standards are inculcated into regulations. As the food and feed industry
pursues implementation of the Food Safety Modernization Act, a paral-
lel activity is underway within the regulatory community involving the
pursuit of standardization. The Animal Feed Regulatory Program
Standard, issued in 2014, represents the third in a suite of standards
designed to achieve reproducibility within and between regulatory
agencies. The other two standards for regulatory bodies are the Manu-
factured Food Regulatory Program Standard and the Voluntary Retail
Food Establishment Regulatory Program Standard.INTERNATIONAL

of aflatoxin measurement in the grain industry, and development of best recall practices. The journal aug-
ments a graduate certificate program in Regulatory Science offered by Texas A&M, the journal is open
access, and authors incur no publication costs. A first of its kind, peer reviewed online journal is accessible

Aflatoxin Kits Evaluation for One Sample Strategy
Since 2010, Office of the Texas State Chemist has been evaluating aflatoxin testing kit performance to as-
sist the industry to improve analytical measurement capability. In 2011, OTSC launched the "One Sample
Strategy" aflatoxin risk management program to address the variability in aflatoxin measurement. OTSC
continues to test and evaluate commercial aflatoxin testing kits that are currently in the market to ensure
their fitness for purpose. In 2014, additional aflatoxin testing kits were evaluated within the Agriculture
Analytical Service at OTSC, including Charm WET XR and Neogen Q+ Green. These kits utilize water
based extraction in place of organic solvents. The evaluation results are available to the public upon re-
quest.Volume 21, No. 3
