The Iowa Department of Public Health recently announced that the agency is investigating more than 10 illnesses that may be related to a freshly prepared fruit and vegetable product sold at a farmers market in east-central Iowa. 

The health department issued the following advice to consumers who buy fresh produce from farmers markets:

* Be aware that any freshly prepared fruit or vegetable product, such as hummus, salsa, cut fruit salad, and guacamole can be a potential health risk if not handled correctly.

* All these products must be kept refrigerated, both before and after the sale.

When shopping at a farmers market, always remember:

* Only buy products from vendors who keep freshly prepared fruit and vegetable products cold, either in refrigerator units or on ice.
   
* Once purchased, keep freshly prepared fruit and vegetable products cold. If you plan to spend a lot of time at the market, bring a cooler or ice pack for storage.
   
* When you arrive home, place these products immediately in the refrigerator and eat within days.
   
* Any freshly prepared fruit or vegetable product that is not properly refrigerated should not be eaten, and should be discarded.
