On-demand Food Safety and Testing Event
Hosted by FoodQualityNews.com and FoodProductionDaily.com
Food safety never lets up from the farm to the table, whether it is your local producer or the conglomerate with a turnover of billions, keeping food safe has to be at the top of the agenda.There is a constant threat from allergens such as nuts and milk, and pathogens like Listeria and Campylobacter, all of which claim human casualties every year. Technologies such as anoparticles, cold plasma, irradiation and High Pressure Processing (HPP) are some weapons used in targeting rapid detection and prevention of pathogen contamination. X-ray and metal inspection and vision systems are also vital components in the constant vigil against contaminants or incorrect labeling forcing a recall. This online event is a chance for experts to offer tips and hear the thoughts of their peers on how to avoid miscommunication and how to establish a proactive, preventative approach by thinking outside the boxes, rather than just ticking them. And if the worst happens, our high-profile speakers from the worlds of manufacturing and scientific research give their professional advice on applying a strategy that limits the damage. Waters is a partnering sponsor of this event.
Routine Quantification of Regulated and Non-Regulated Lipophilic Marine Biotoxins in Shellfish
Presented by Ramesh Rao, Director, Food & Environmental Business Development, Waters Corporation
Consumption of shellfish contaminated with biotoxins can cause severe intoxications in humans, such as diarrhetic shellfish poisoning (DSP). Due to their lipophilic properties, DSP toxins are often classified as lipophilic marine biotoxins. The complexity of the lipophilic marine biotoxins lies in the variety of physiochemical properties, such as carboxylic acids, sulfonic acids, and amino and imino functionalities. Since July 2011, the official EU method for control of shellfish for the presence of lipophilic marine biotoxins has been LC/MS/MS, although the traditional ‘mouse bioassay’ method is still used in many parts of the world. The EU reference LC/MS/MS method is based on a fixed extraction procedure followed by separation using conventional LC separation, with either an acidic mobile phase or alkaline mobile phase and detection by tandem quadrupole MS. In this presentation Ramesh Rao describes a rapid, robust UPLC/MS/MS method for the analysis of both regulated and non-regulated lipophilic marine biotoxins in shellfish. Compared to conventional HPLC/MS/MS, the speed of analysis increased four-fold, from 20 min to 5 min per analysis.
