Interestingly, Hawaii State Department of Health tested and found Listeria in a sample of product, and a recall was issued on January 11, 2024. Using whole genome sequencing, they were able to link these additional cases and show that this firm's product was responsible for many cases over many years.
"A sample of Rizo Bros Aged Cotija tested positive for Listeria monocytogenes during sampling conducted by the Hawaii State Department of Health’s Food and Drug Branch in January 2024.In response to that finding, Rizo Lopez Foods, Inc. voluntarily recalled one batch of Rizo Bros Aged Cotija Mexican Grating Cheese (8oz) on January 11, 2024. CDC and FDA reopened the investigation in January 2024 after new illnesses were reported in December 2023 and whole genome sequencing (WGS) analysis of the cotija cheese sample showed that it is the same strain of Listeria that is causing illnesses in this outbreak."
