whole_genome_sequencing_blog.jpgThe practice of whole genome sequencing (WGS) has received a great deal of attention in the food industry and among industry trade associations in recent years. Whole genome sequencing is a process that uses laboratory methods to determine or map the complete DNA sequence of an organism’s genome. Each microorganism has a unique genetic fingerprint that can be identified and traced using WGS. 

Disease detectives use WGS as an important tool in foodborne illness outbreaks and recall situations. It provides genetic information about the germs (microorganisms) making people sick. This information improves our ability to detect, investigate and stop future foodborne outbreaks.

government_report_blog.jpgGovernmental agencies overseeing the food industry have traditionally had a love/hate relationship with the sector. With the advent of new regulations, this relationship is sure to face its share of future challenges as well. However, government agencies ultimately take responsibility for the public’s health, and they provide support to the industry to keep consumers safe. Some of the tools made available to the public, as well as food safety professionals, identify public health issues related to various etiologic agents. 

Both the Food and Drug Administration (FDA) and U.S. Department of Agriculture (USDA) provide daily updates on food recall events, as well as recalls of dietary supplements. Additionally, a compilation of both FDA and USDA events is available to the public. In keeping up with the Joneses, apps and widgets also offer a way the food industry or consumers in general to stay informed. The information available from these sources includes the etiologic agent involved, product type and other important data.
