Eat fish, choose wisely
Some fish from specific areas in Utah may contain chemicals that could pose health risks. When contaminant levels are unsafe, Utah Public Health Officials issue fish consumption advisories. These advisories outline recommendations for limiting intake of specific fish at specific locations. Fish advisories have been issued in Utah due to elevated levels of arsenic, mercury, selenium, and PCBs.
