A Study from the University of Valencia found dangerous levels of bacteria in 43% of the orange juices used at Spanish bars for mixed drinks.
The study published in the Food Control Magazine analyzed the orange juice used in 190 Spanish bars and found enterobacteriaceae in nearly 50% of the samples.
The percentage of bacteria nearly doubled in restaurants or bars that kept their orange juice in metallic containers, as opposed to serving it fresh.
Escherichia coli and salmonella both belong to the Enterobacteriaceae family, and both can cause serious digestive issues.
