In the debut installment of the Food Safety Five Newsreel, we discuss an ongoing multistate outbreak of Escherichia coli infections linked to onions served at McDonald’s restaurants. The episode also takes a look at legislation passed in California that marks the country’s first mandatory food date labeling reforms.
The U.S. Centers for Disease Control and Prevention (CDC) has officially named Taylor Farms onions served at McDonald’s as the source of the recent Escherichia coli outbreak, and has reported 90 illnesses, 27 hospitalizations, two cases of Hemolytic Uremic Syndrome, and one fatality.
Testing has shown no sign of Escherichia coli contamination in McDonald’s Quarter Pounder beef patties, and traceback and epidemiological data have ruled out beef as the cause of the ongoing E. coli outbreak. Quarter Pounders have returned to the menu at affected McDonald’s locations—without slivered onions.
Amid the ongoing E. coli outbreak, Taylor Farms has been confirmed as the onion supplier to the affected McDonald’s locations. As a result, national restaurant chains are proactively pulling onions from their menus. FDA is still investigating whether onions are the vehicle of illness.
A foodborne illness outbreak linked to McDonald’s Quarter Pounders contaminated with Escherichia coli has caused 49 illnesses, ten hospitalizations, and one death in ten states. Slivered onions used on the sandwiches are the probable vehicle of illness.
A recent study of genomic data for Campylobacter from 2009–2019 found a steep increase in human infections attributable to poultry, as well as a concerning rise in the proportion of multidrug-resistant isolates. Campylobacter isolates associated with poultry were found to harbor the most antimicrobial resistance (AMR).
Following the history of serious food safety noncompliances at Boar’s Head’s Jarratt, Virginia plant, which led to a fatal listeriosis outbreak, USDA’s Inspector General has launched an internal investigation into the agency’s handling of the repeated sanitary violations found at the facility.
Penn State University researchers have demonstrated the usefulness of wastewater monitoring for foodborne pathogen surveillance, after successfully isolating Salmonella from wastewater samples and linking them to clinical isolates from an existing foodborne illness outbreak.
According to recently released U.S. Department of Agriculture (USDA) inspection reports, in the year leading up to the deadly Listeria monocytogenes outbreak caused by Boar’s Head deli meats, serious noncompliances with food safety regulations were observed regularly at the facility responsible.
To celebrate National Food Safety Month in September, the National Restaurant Association and ServSafe are offering special educational content for foodservice and food retail establishments to deeply explore the causes of foodborne illnesses and how to prevent and respond to outbreaks.
