The enhanced ability to link infections together and trace them back to the source over the last decade through new technology, such as whole genome sequencing, may explain some of these findings. But whether we’ve always had a food safety problem and now we can see it, or the problem is getting worse in recent years, misses the point. Americans should be confident that their food is safe and uncontaminated from dangerous bacteria like E. coli and salmonella.
In addition, the number of recent high-profile recalls that stick in the public mind are the tip of the iceberg. The Centers for Disease Control and Prevention estimate that 1 in 6 people in the U.S. get foodborne illnesses with 128,000 individuals hospitalized and 3,000 dying every year. These infections include E. coli and salmonella poisoning as well as Clostridium, Campylobacter and Toxoplasma gondii. The cumulative public health risk of foodborne illness warrants further study into causes and solutions.
