Current toxin detection mechanisms are insufficient in comparison to a software defined networking system with P2P compatibility in regards to real time detection. In regards to current mechanisms, this involves both wet chemical as well as physical devices and/or buoys. The introduction of new technologies in regards to network latency in relation to novel detection methods is what will be the cornerstone of this research. The importance of this field is to draw conclusions in regards to technological implementations in relation to detection, time, network latency and quality of the data.

Abstract Background PSP toxins have been reported in non-bivalve shellfish species, including crustaceans and gastropods. Routine surveillance of these species is currently conducted in parts of England. To date detection methods have not been validated for these matrices. Validation is required to ensure the test is fit for purpose, to give greater confidence in any results generated and ultimately facilitates accreditation. Objective The aim was to test and validate two independent PSP toxin detection methods previously validated for bivalve shellfish matrices, for applicability to commercial non-bivalve species of interest. Methods Matrices were shrimp (Crangon crangon), common whelk (Buccinum undatum) and edible crab (Cancer pagurus). The two methods assessed were the pre-column oxidation LC-FLD AOAC 2005.06 Official Method of analysis and an internationally validated HILIC-MS/MS method. Brown and white crab meat were assessed separately. Results A refined extraction protocol was implemented with an increased solvent to sample ratio. The same extraction protocol was utilized for both methods, allowing both methods to be run simultaneously. Method sensitivity, recovery, repeatability, and method uncertainty were characterized in all matrix/toxin combinations. Overall, both methods performed similarly to that previously reported in bivalve molluscs. Acceptability of the majority of toxin/matrix combinations was evidenced through comparison of method performance characteristics against specific performance criteria, including Horwitz ratio values. Conclusions Both PSP toxin detection methods were found to provide acceptable performance for the monitoring of shrimp, whelk and crab species. Highlights Two PSP toxin detection methods have been single-laboratory validated successfully for three non-bivalve shellfish species.

Abstract Staphylococcus aureus is a Gram-positive bacterium capable of causing a wide array of infections. Generally a commensal organism, S. aureus encodes several virulence mechanisms that contribute to disease progression. This review highlights toxins as a secreted virulence factor by S. aureus, the diseases that manifest as a result, and the methods used to detect them. In particular, the advantages and limitations of current toxin detection methods are discussed.
