Also in the news report:
"At this time, it is unknown if we are experiencing a higher prevalence of E.coli in flour than normal, if this is an issue isolated to General Mills' flour, or if this is an issue across the flour industry. The newer detection and genome sequencing tools are also possibly making a connection to flour that may have always existed at these levels."Whole genome sequencing has changed the game in terms of tracking the organism responsible for foodborne illness outbreaks. But is this why see these outbreaks, or is there something occurring in the food supply chain, specifically higher contamination levels of E. coli in grains.
