Special Recognition Award

Harvey W. Wiley Award

Presented to: Michelangelo Anastassiades, CVUA Stuttgart-European Union Reference Laboratory for Pesticides Requiring Single Residue Methods (EURL-SRM), Stuttgart, Germany

AOAC INTERNATIONAL is proud to present the 2023 Harvey W. Wiley Award, the Association’s highest honor for lifetime scientific achievement, to Michelangelo Anastassiades. He joined the CVUA Stuttgart in 1994 and has been working in the field of pesticide residues ever since. From 2000 to 2002, Anastassiades worked as a visiting scientist at the Eastern Regional Research Center of the U.S. Department of Agriculture. He returned to the CVUA Stuttgart in 2002 and has been heading the EURL-SRM, which is funded by the European Commission (EC), since 2006. The duties of the EURL include development of methods, organization of proficiency tests, technical assistance to the EC and European Food Safety Authority, as well as trainings and workshops for National Reference Laboratories of EU Member States.

Anastassiades’ most significant contribution to the development of standards and methods is an analytical approach called QuEChERS (pronounced “kechers”), which stands for quick, easy, cheap, effective, rugged, and safe. It is an extraction process for testing for most pesticide residues and their metabolites. The QuEChERS method led to the development of two important official methods for pesticide residue analysis: EN 15662 and AOAC Official MethodSM 2007.01.

Anastassiades is currently examining ways to cover 20-25% of pesticides and pesticide metabolites not amenable to the basic QuEChERS method. This entails finding analytes with similar properties and grouping them as much as possible under the same basic techniques. In addition, many labs have expanded QuEChERS to include other classes of compounds for subsequent quantification.

Anastassiades received his Ph.D. at the University of Hohenheim/Germany in 2001, with a thesis on the analysis of pesticide residues using supercritical fluid extraction.

The Harvey W. Wiley Award is presented each year to a scientist, or group of scientists, who has made an outstanding contribution to analytical methodology in an area of interest to AOAC INTERNATIONAL. The award consists of US$5,000, an award plaque, and reimbursement of travel expenses incident to attending the AOAC Annual Meeting and Exposition.

Presented to: Pushpa Deore, Vasantdada Sugar Institute (VSI), Maharashtra, India

Pushpa Deore is a Ph.D. Scholar at VSI associated with Savitribai Phule Pune University. She is currently working under the supervision of R.M. Devarumath from VSI and Anuradha Upadhyay and Ahammed Shabeer T.P. from Indian Council of Agricultural Research-National Research Center for Grapes.

Deore’s doctoral dissertation focuses on “Pesticide Effect on Grape Phyllosphere Microbiome Dynamics Regarding Grape and Wine Quality,” which integrates molecular, analytical, microbiological, and biochemical approaches. The project provided valuable insights on potential biomarkers identification, which could be a useful tool for organic produce authentication. The pathways affected could help to understand pesticide interaction with grape metabolome with the quality estimation. The microbial diversity of grapes observed during metagenome analysis will help to develop strategies for improving the ecosystem. Novel pesticide-degrading isolates identified in the study could be exploited for the bioremediation of pesticides.

Deore previously worked as a grape breeder and molecular biologist, where she developed expertise in molecular and analytical techniques regarding plant protection and improvement, which benefits the farming community. Her research work has been presented on national and international platforms and received many recognitions.

Inés Cereijo Technical Division of Reference Materials (TDRM) Student Award

Presented to: Andres F. Ortega, Cornell University, Ithaca, New York, USA

Andres Ortega is a Ph.D. candidate mentored by Mike Van Amburgh, whose group works to further develop the Cornell Net Carbohydrate and Protein System (CNCPS). CNCPS is a nutritional model used by dairy farmers around the world to formulate cattle diets and predict productive performance. Ortega’s research focuses on amino acids (AA), the building blocks of protein composed of nitrogen (N). During his graduate program, Ortega used standard reference materials to develop a novel method to analyze the AA composition of different substrates using HILIC and liquid chromatography-tandem mass spectrometry to better characterize the chemical composition of various model components. The method will be used to examine how nonessential AA in diet formulation can improve dairy cattle productive efficiency, which can result in less N excreted into the environment and lower feed costs for farmers.

In the long term, Ortega is interested in gaining experience with other, more complex analytical techniques necessary to investigate nutrient utilization and metabolism in any animal.

The AOAC INTERNATIONAL Inés Cereijo Technical Division on Reference Materials (TDRM) Award is offered annually to both undergraduate and graduate students at any college or university to support students promoting awareness of the need for method performance evaluation early in a chemist’s career, using reference materials.

Method of the Year – Chemistry

Presented for: AOAC Official MethodSM 2020.07 Measurement of Available Carbohydrates in Cereal and Cereal Products, Dairy Products, Vegetables, Fruit, and Related Food Products and Animal Feeds

Barry V. McCleary

Method Authors: Barry V. McCleary, FiberCarb Consultants; Ciara McLoughlin and Vincent A. McKie, Neogen Corp.

The AOAC ERP for Dietary Starch and Fiber Methods recommended AOAC Official MethodSM 2020.07 for Final Action status, which was approved in 2022. Traditionally, carbohydrates are calculated by difference from other determinations of protein, fat, moisture, ash, alcohol, etc. from the total weight of the food, and total available carbohydrates are estimated by the subtraction of dietary fiber. The method accomplished a procedure for direct determination of available carbohydrates by specific determination of digestible starch, maltodextrins, maltose, isomalto-oligosaccharides, isomaltose, sucrose, lactose, glucose, fructose, and galactose in a variety of food matrices [Journal of AOAC INTERNATIONAL Vol. 106, No. 2, pp 370–383(2023)].

Andrew Lienau

Method Authors: Andrew Lienau, MilliporeSigma; M. Joseph Benzinger Jr., Benjamin Bastin, Erin Crowley, Kateland Koch, and Wesley Thompson, Q-Laboratories

Cronobacter infections are an emerging opportunistic foodborne pathogen particularly concerning infants. Cronobacter can remain viable for long periods in low-moisture foods, and outbreaks associated with dry foods have occurred in infant formula, infant cereal, powdered milk, herbal teas, and starches. AOAC Official MethodSM 2021.08 Assurance® GDS for Cronobacter Tq II (GDS Cronobacter) assay is an automated nucleic acid amplification system for the detection of Cronobacter in infant formulas, infant cereals, ingredients, and environmental samples [Journal of AOAC INTERNATIONAL Vol. 106, No. 3, pp 711–724(2023)].

The AOAC OMB awards recognize significant contributions and meritorious volunteer service to the AOAC analytical sciences community.
