State and local public health officials have cleared Margaritas restaurant to reopen in Canton, Connecticut, six days after the Tex-Mex eatery was ordered to close because of an outbreak of salmonella.

Of the 15 customers who contracted the bacteria after eating at the restaurant, 4 were hospitalized. No other outbreaks were reported in the state during that time.

The source of the contamination has yet to be found. At least one food sample, containing fresh produce, is still being tested.
