Nearly two weeks after a salmonella outbreak prompted their closing, Clover Food Lab expects to reopen its four restaurants tomorrow.

The Cambridge, Boston, Brookline and Burlington eateries and seven food trucks will reopen, provided its 128 employees, who have been screened for Salmonella, are cleared to return to work.

A commissary kitchen in back of the Cambridge restaurant will remain closed until Clover receives a wholesale license from the state Department of Public Health.

At least 15 people contracted salmonella, germs that cause an infectious disease of the bowel but that also can spread to other systems of the body, such as the blood and bones.
