DNA Microarray Technology in Food Technology

As modern food production has become more and more centralized and food delivery routes become longer, single foodborne outbreaks have expanded to wider and wider areas. This has presented a challenge in attempts to solve these outbreaks. Molecular typing methods used together with relevant analytical epidemiology enable better identification of epidemics. Molecular diagnostics will increasingly play a key role in food safety related to genetically modified foods, foodborne pathogens and novel nutraceuticals [73]. DNA microarray technology provides a flexibility in molecular diagnostics by permitting the simultaneous analysis oflarge sets of genes. Thus, automation of assay and novel bioinformatics tools make DNA microarrays a robust technology for diagnostics in food technology as well. Efforts to develop diagnostic custom arrays and simplified bioinfor-matics tools for field use are warranted [73].
