Researchers still haven’t found the source of the salmonella outbreak after spending five days studying food from the Old South restaurant in Camden.

Using left over turkey, Microbiologist Beth Johnson has to liquify the food. She then pours it into tubes and places them into an incubator where the salmonella has a chance to grow if it’s there, "This black one right there could possible be salmonella."

After four days of being examined in the food lab, samples that could be some form of salmonella are sent to bacteriology for confirmation. It’s off to yet another lab if it’s a positive.

The DHEC Molecular Department processes the positive cultures from humans and the food to see if they are related. It could take several days before all tests are done.
