The CAHAN advisory says the MDR Salmonella serotype Newport is harder to treat due to its resistance to antibiotics, and patients may have a higher risk of developing serious complications.
SAN DIEGO — The California Health Alert Network for San Diego County issued a health advisory, warning travelers to and from Mexico about an increase in Salmonella infections due to a multidrug-resistant strain of the bacteria.
Many travelers who were infected with this strain reported eating beef, cheese , beef jerky or carne seca before they got sick, the CAHAN says. The health advisory also provided a deeper dive background on the MDR Salmonella Newport strain. From 2015 to 2019, this strain was the second most common identified among San Diego County patients, accounting for 11% of cases. Two multistate clusters of MDR Salmonella Newport impacted some San Diego County residents since 2018. In 2018-19, 31 cases were reported locally, while 14 cases were reported in late 2021.
