State health officials are warning the public to restrict their consumption of bass because of concerns about their mercury content.

The Kansas Department of Health and Environment said Monday largemouth, smallmouth and spotted bass should be eaten only once per week.

The department says women who are pregnant, might become pregnant or are nursing; and children under the age of 18 should eat Kansas-caught bass only once a month.

The health department says restrictions are necessary because of the levels of mercury, which can cause health problems, particularly to fetuses and children.
