Vendors at the Modesto Certified Farmers Market will be taking a closer look at the money customers hand them today after a spate of incidents in which people have paid for their fruits, nuts and vegetables with fake bills, said Marie Uber, the market's manager.
The market is open Saturdays and Thursdays.
Uber said vendors received four counterfeit $20 bills and one $50 bill.
There also have been other incidents since the market opened for this season on April 30.
The market is open today from 7 a.m. to noon on 16th Street in downtown.
