Salmonella can grow on bruised blueberries kept at shipping or retail display temperatures, according to a new study in the Journal of Food Protection. The study was conducted by researchers at the Department of Food Science and Human Nutrition, Citrus Research and Education Center at the Institute of Food and Agricultural Sciences at the University of Florida,
Strawberries and blueberries harvested at or near full-ripe maturity and softer than those that are not as ripe and therefore more susceptible to bruising during harvest and transport. The researchers wanted to see how E. coli O157:H7 and Salmonella behaved on bruised fruit and intact fruit at shipping temperature, 35.6˚ F, and retail display 59.9˚ F. So they The bruised the berries inoculated them with bacteria and observed.
They found that the E. coli O157:H7 and Salmonella did not grow on strawberries at shipping or retail display temperatures. But that Salmonella did grow on bruised fully ripe blueberries at retail display temperatures.
Salmonella causes an infection called salmonellosis. Symptoms include abdominal cramps, fever, vomiting and diarrhea that can be bloody.
