SACRAMENTO – A state fish advisory issued today for Diamond Valley Lake in Riverside County provides safe eating advice for black bass species, Common Carp, Inland Silverside, and sunfish species.

Diamond Valley Lake is the largest reservoir in Southern California and is located approximately 90 miles southeast of Los Angeles, near Hemet. The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) developed the recommendations based on the levels of mercury and PCBs found in fish caught from the lake.

“Many fish have nutrients that may reduce the risk of heart disease and are excellent sources of protein,” said Dr. Lauren Zeise, director of OEHHA. “By following our guidelines for fish caught in Diamond Valley Lake, people can safely eat fish low in chemical contaminants and enjoy the well-known health benefits of fish consumption.”

When consuming fish from Diamond Valley Lake, women ages 18-49 and children ages 1-17 should not eat black bass species. They may safely eat a maximum of three total servings per week of Inland Silverside, or two serving per week of sunfish species, or one total serving per week of Common Carp.

Women ages 50 and older and men ages 18 and older may safely eat a maximum of seven total servings per week of Inland Silverside, or six total servings per week of sunfish species, or one total serving per week of black bass species or Common Carp.

One serving is an eight-ounce fish fillet, measured prior to cooking, which is roughly the size and thickness of your hand. Children should be given smaller servings. For small fish species, several individual fish may make up a single serving.

A poster with the safe-eating advice for Diamond Valley Lake is available on OEHHA’s website in both English and Spanish. For fish species found in Diamond Valley Lake that are not included in this advisory, OEHHA recommends following the statewide advisory for eating fish from California lakes and reservoirs without site-specific advice.

Mercury is a naturally occurring metal that is released into the environment from mining and burning coal. It accumulates in fish in the form of methylmercury, which can damage the brain and nervous system, especially in developing children and fetuses. Because of this, OEHHA provides a separate set of recommendations specifically for children up to age 17, and women of childbearing age (18-49 years).

PCBs (polychlorinated biphenyls) are a group of industrial chemicals. At high levels of exposure, they can cause health problems, including cancer. Although they were banned in the United States in the late 1970s, PCBs persist in the environment from spills, leaks or improper disposal. PCBs accumulate in the skin, fat, and some internal organs of fish. In order to reduce exposure from PCB contaminated fish, OEHHA recommends eating only the skinless fillet (meat) portion of the fish.

Eating fish in amounts slightly greater than the advisory’s recommendations based on mercury or PCBs is not likely to cause health problems if it is done occasionally, such as eating fish caught during an annual vacation.

The Diamond Valley Lake advisory joins more than 100 other OEHHA advisories that provide site-specific, health-based fish consumption advice for many of the places where people catch and eat fish in California, including lakes, rivers, bays, reservoirs, and the California coast. Advisories are available on OEHHA’s Fish Advisories webpage.

OEHHA’s mission is to protect and enhance the health of Californians and our state’s environment through scientific evaluations that inform, support, and guide regulatory and other actions.
