Journal of Dairy Science® focuses on infant formula shortage and improved detection methods

Online article collection explores detection and control of Cronobacter sakazakii that contributed to supply disruption

Philadelphia, May 31, 2022 – The US shortage of both liquid and powdered infant formula (PIF) that has created struggles for parents seeking supplies highlights the critical need for improved detection methods aimed at preventing formula shortages. In response, the Journal of Dairy Science (JDS) has created a collection of articles aimed at improved detection methods to counter bacteria in PIF.

Multiple factors have played a role in the current situation, but according to Michael J. Miller, PhD, professor of food science and human nutrition at the University of Illinois Urbana-Champaign, “The shortage is in part related to Cronobacter sakazakii. One commercial facility has been linked to an outbreak of C. sakazakii in PIF, which shut the facility down. Once one facility was offline, there wasn’t enough PIF capacity in the US industry to compensate. The lack of resiliency in food systems is a problem when something catastrophic happens, such as a pandemic, outbreak, massive hurricane, or war.”

Several relevant articles have been published in JDS. Most are centered on improved detection methods, important to the current situation. These articles focus on methods to quickly and accurately measure C. sakazakii in PIF samples and explore ways to counter C. sakazakii through the use of silver nanoparticles, tea polyphenols, radio frequency dielectric heating, and carbon dioxide. These methods show promise in reducing or destroying C. sakazakii, which may ultimately offer a solution to responding to and preventing the spread of outbreaks in infant formula and getting formula back on store shelves.
