AOAC 2018 Preliminary Program

• Johanna Murphy, Canadian Food Inspection Agency (CFIA) Qualitative Method, Easy to Validate! Is it Really the Case? Why Part 4 is Needed • Irene Iugovaz, Health Canada Health Canada: Quantitative Methods Challenges! Symposium: New Blood 2018 — Developing Methods for the Detection of Important Chemical Analytes, Residues and Contaminants The detection of chemical analytes, residues, and contami- nants in consumer commodities and the environment is an interesting, challenging, and continually evolving discipline. In order to maintain a vibrant and active Chemical Contaminants community in AOAC, young scientists must be encouraged to work in these areas. The purpose of this session is to provide new members of our community an opportunity to present their work for the first time at a technical session at the AOAC Annual Meeting. The presentations in this session represent the broad interests of the AOAC Chemical Contaminants Community that emphasize the analysis of pesticide and veterinary drug residues, environmental and industrial contaminants, adulterants, natural toxins, and other important chemicals in food, feed, environmental samples, and other relevant matrices. Due to its popularity, there has been a New Blood session at every AOAC Annual Meeting and Exposition ever since the first New Blood Technical Session was held at the 124th Annual Meeting in 2010 in Orlando, FL. The sessions at the second, third, fourth, fifth, sixth, seventh, and eighth meetings in New Orleans, Las Vegas, Chicago, Boca Raton, Los Angeles, Dallas, and Atlanta have either been the most or one of the more heavily attended sessions at each of those meetings. It is hopeful to continue the tradition to have a New Blood session at every AOAC meeting dedicated to new and talented AOAC scientists, stakeholders, and members.

10:15 am – 11:45 am Symposium: Solving Everyday Problems in the Dietary Supplement Analytical Laboratory without Breaking the Bank Dietary supplements are often complex mixtures consisting of natural products, herbs or other botanicals, vitamins, minerals and/or amino acids. Because of the complexity of the finished products, not very many official methods are available for their analysis. Development of accurate analytical methods for these products requires optimization of each step, including sample extraction, sample clean-up, selection of appropriate instruments, and deciding on the best instrumental parame- ters, just to name a few. There are many questions dietary supplement laboratories face every day: How can a laboratory ensure that the results they provide to the customers are scientifically valid? How can the performance of an analytical laboratory be improved with- out making large additional investments? How can one find reference materials when a sample has multiple botanicals and vitamins? What is the proper way to use statistical tools in the data evaluation process, and in creating the final analytical report? This session will tackle these question — feel free to bring your own problem to discuss at the end of the session!

HPLC Columns: Traditional, Core-Shell or Fully Porous? • Jane Weitzel, Consultant How to Create Reportable Values with Measurement Uncertainty that are “Fit for Purpose” Symposium: Advanced Listeria Detection and Control: What’s the State of the Art Today? Twenty years ago, Listeria was thought to be a problem associated nearly exclusively with ready to eat meat products and soft cheeses. In recent years, however, the range of foods associated with Listeria outbreaks has expanded. As the food safety community has developed a deeper understanding of the scope of products that can be contaminated, more methods for detecting, typing, and controlling Listeria have been developed to assist in reducing the risks associated with this pathogen. This symposium will cover recent advances in developing tools to lessen the chance of Listeria outbreaks through more rapid detection and subtyping, greater under- standing of environmental reservoirs and the use of preventive controls. Technologies that enable very rapid screening and subtyping of Listeria from environmental samples, combined with environmental mapping software, can dramatically change how food producers understand, address and mitigate contamination risk in their facilities. The symposium will also address issues around managing information in the new era of FSMA-driven swab-a-thons, including the question “How much information is too much?” It will conclude with real-world
