Black infants face higher salmonella infection risk

When compared with white or Asian infants, black infants were at greater risk for salmonella infection, and targeted interventions in certain populations may be of help, according to recently published data.
Lay Har Cheng, MD, MSPH, of the Levine Children’s Hospital in Charlotte, N.C., and colleagues looked at Foodborne Diseases Active Surveillance Network data on salmonella infections between 1996 and 2008 in infants aged younger than 1 year.

The researchers said when compared with the average annual incidence rate of salmonellosis per 100,000 among white (81.1) or Asian infants (129.7), black infants had the highest rate (177.8). In addition, the average annual incidence rate for invasive infection was highest among black infants (9.4% vs. 6.4% for Asian infants and 3.6% for white infants; P<.001).
The researchers wrote: “Incidence of all salmonellosis remained stable for whites from 1996-1998 through 2008, but blacks had a sustained decrease, with relative risk of 0.48 (95% CI, 0.37-0.63) in 2008 compared with 1996-1998. However, 2008 incidence remained highest among blacks.”
They also wrote that the decrease “suggests that future improvements may be possible for other population subgroups.”
