Alabama Health Department officials are testing a church area where eight people were infected with E-coli bacteria.
Baldwin County Health Department spokesman Teresa Porter says 20 people became ill after attending a church pot luck dinner in Daphne, Alabama over the weekend.
Health officials say there is up to a 10 day incubation period for the organism so other cases may still surface.
The church is cooperating with the health department to determine the source of the bacteria.
Three of the eight infected are still in the hospital.
There conditions and identities have not been made public.
