WASHINGTON - The U.S. government has increased the number of people reported being sickened in a record salmonella outbreak in which tomatoes are the leading suspect.
Investigators are testing other types of fresh produce.
There have been 943 reported cases nationwide, with at least 130 hospitalizations since mid-April after the first salmonella illnesses appeared.
The Food and Drug Administration says that compares with a total of 922 people about two days ago and 869 reported earlier in the past week.
On Tuesday, the government said it would test numerous other kinds of fresh produce while insisting that tomatoes remain the leading culprit.
Investigators have kept quiet about exactly what other vegetables are getting tracked but said they're looking at items commonly served with fresh tomatoes.
Investigators with the Centres for Disease Control and Prevention have interviewed people sickened in June to find out what they ate and to compare their diets with those of healthy relatives and neighbours.
Officials so far haven't revealed early findings, except to say they support the investigation's new move.
Among the possibilities FDA has said it was exploring is whether tomatoes and other produce are sharing a common packing or shipping site where both might become contaminated, or whether multiple foods might be tainted while being grown on adjoining farms or with common water sources.
