Michigan's 2026 Eat Safe Fish Guides: What Every Angler Needs to Know Before Their Next Meal
Every spring, Michigan anglers pull walleye out of the Detroit River, haul in chinook salmon from Lake Michigan tributaries, and fry up bass caught on a quiet Sunday morning. It's one of the great pleasures of living in a state surrounded by more freshwater than almost anywhere else on earth. But that ritual — the catch, the clean, the cast-iron skillet — now comes with a more complicated set of instructions than it once did. The Michigan Department of Health and Human Services has made that clear with its newly released 2026 Eat Safe Fish Guides, and the picture they paint is detailed enough to deserve serious attention from anyone who eats what they catch.
The Michigan Department of Health and Human Services released its 2026 Eat Safe Fish Guides, cautioning Michiganians who eat fish about chemicals likely to be found in different species found in waterways around the state. The release comes as part of an annual program, but the 2026 edition reflects a water quality landscape that has grown more complex with each passing year — one shaped by decades of industrial activity, agricultural runoff, and the proliferating presence of so-called forever chemicals in Michigan's rivers and lakes.
The Scale of the Program
The guidelines are based on the levels of contaminants found in fish filets tested by the Michigan Department of Health and Human Services' Bureau of Laboratories. That's not a passive exercise. The state's testing apparatus works in tandem with environmental monitoring to produce a document that, for serious anglers and families who supplement their diet with locally caught fish, is essential reading.
In total, the guides provide consumption guidelines for 696 Michigan waterbodies. That number alone gives a sense of both the scope of the effort and the breadth of Michigan's fishing culture. This isn't a narrow advisory about a handful of polluted urban waterways — it's a statewide public health project that touches nearly every corner of the Lower and Upper Peninsulas. The guides break the state down into five regions — the northeast, northwest, southeast, southwest and the Upper Peninsula — with a guide for each.
The Michigan Department of Environment, Great Lakes, and Energy's Fish Contaminant Monitoring Program collects fish throughout Michigan each year to test them for chemicals. Sampling locations are chosen based on connections to known or suspected contamination sites and/or popular sport fishing areas. Critically, members of the public can request EGLE to test fish for chemicals through a Targeted Monitoring Request. That means anglers who fish water bodies not already covered in the guide actually have a mechanism for getting answers, rather than simply guessing.
What Changed in 2026
The 2026 update isn't simply a reprint of last year's data. This year, there were 59 guidelines that were relaxed and 65 that became more protective than previous years. That bidirectional shift matters. It tells a story about water quality that is neither uniformly improving nor uniformly degrading — it's a patchwork. Some waterways are getting cleaner as remediation efforts take hold; others are being flagged more aggressively as new testing data comes in, particularly around PFAS compounds that have been tracked in Michigan's fisheries for over a decade.
Michigan has been routinely testing fish filets for PFAS since 2012. That means the state now has more than a decade of longitudinal data on forever chemical accumulation in fish tissue — and the 2026 guidelines reflect that maturing body of evidence. The fact that 65 guidelines became more protective this year, not fewer, suggests that PFAS monitoring is still turning up new or worsening contamination in parts of the state where anglers may have assumed the water was clean.
The scale of Michigan's PFAS problem puts this in perspective. According to state records, as of March 2026, there are 340 sites in Michigan where PFAS has contaminated groundwater and the sources are known, and of the fish tested for the Michigan fish consumption guidelines since routine PFAS monitoring began, more than 90% have some level of PFAS detected in the edible portion.
The Chemicals You're Actually Eating
For many anglers, the word "contamination" conjures industrial disaster imagery — orange plumes pouring from smokestacks, oil slicks on water. The reality of chemical exposure through fish consumption is far subtler and, for that reason, more dangerous. You will not be able to see any of the chemicals, even mercury or PFOS, in the fish. You also can't taste or smell the chemicals listed in the guide. Some very clear lakes or rivers can still have fish with higher levels of chemicals. A pristine-looking lake is no guarantee of a clean catch.
Contaminants present in some wild-caught fish include dioxins, polychlorinated biphenyls (PCBs) and perfluorooctane sulfonate (PFOS) — otherwise known as "forever chemicals" — which are all linked to cancer and other illnesses. Fish can also contain mercury, which can damage the brain and nerves. Each of these contaminants works differently in the human body. PCBs and dioxins are fat-soluble, meaning they accumulate in fatty tissue over time and don't leave the body easily. PFOS has a similar bioaccumulation problem. Mercury, particularly methylmercury, targets the central nervous system.
Not everyone will get sick from eating too many of these chemicals. The chemicals in the fish won't make you sick right away, either. Some people will be fine after years of eating fish with these chemicals in them. Others can have health problems. That unpredictability is precisely why the guidelines take an abundance-of-caution approach — they're designed to be protective across the full range of human health variables, not calibrated for the healthiest possible member of the population.
PCBs: The Persistent Industrial Legacy
Polychlorinated biphenyls were manufactured in the United States from the 1920s until their ban in 1979, used extensively as coolants and insulating fluids in industrial equipment. Decades after the ban, PCBs remain stubbornly present in the sediments of rivers and lakebeds throughout the Great Lakes region. They move up the food chain efficiently — small organisms accumulate them, larger fish eat those organisms, and the concentrations magnify at each step. Bottom-feeding fish and large predatory species consistently show the highest levels, which explains why carp and some bass species appear so prominently in Michigan's advisories year after year.
PFOS and the Forever Chemical Problem
PFOS is a type of per- and polyfluoroalkyl substance that is not naturally found in the environment and can be harmful to health. PFOS is a chemical of concern when eating fish. The "forever" label comes from the fact that PFOS and related compounds do not break down in the environment or in living tissue under normal conditions. Once they're in a body of water, they stay. The Eat Safe Fish program issues Do Not Eat advisories when the average level of PFOS found in fish filets exceeds 49.6 parts per billion. That threshold drives some of the most severe advisories in the 2026 guide, particularly in waterways near former industrial sites, military installations, and areas with a history of PFAS-containing firefighting foam use.
Species-by-Species: What Metro Detroit Anglers Need to Know
The southeastern corner of Michigan — Wayne County, Washtenaw County, Macomb County — sits at the intersection of several heavily monitored waterways. The Detroit River, the Rouge River system, the Clinton River, Belleville Lake, and Lake St. Clair all feature prominently in the 2026 advisories, and the specific warnings are worth laying out in plain terms.
Lake St. Clair and the Detroit River
Lake St. Clair: Do not eat muskellunge due to mercury. That's a hard stop for muskie anglers who were planning to keep their catch. Limit consumption of sturgeon and white (silver) bass due to PCBs.
On the Detroit River, the advisory is more nuanced but covers a longer species list. Limit consumption of carp, catfish and white (silver) bass due to dioxins and PCBs; limit consumption of freshwater drum, largemouth bass, smallmouth bass and suckers over 18 inches due to PCBs. For a river that draws significant recreational fishing traffic from both the Michigan and Ontario sides, these limitations are meaningful. The size threshold on suckers is worth noting — larger, older fish have had more time to accumulate contaminants, which is a pattern that repeats throughout the guide.
The Rouge River System
The Rouge River and its network of branches represent one of the most heavily contaminated watersheds in the metro area, and the 2026 guide reflects that with a set of advisories that vary by specific stretch of the river. Rouge River (main, upper and lower branches): Do not eat bluegill, carp, rock bass or sunfish due to PFOs. On the middle branch, the warnings shift depending on which dams you're fishing between. Rouge River (middle branch, from Nankin Dam to Newburgh Dam): Limit consumption of northern pike due to PCBs. Rouge River (middle branch, from Newburgh Dam to Wilcox Dam): Do not eat largemouth bass or smallmouth bass due to PFOs.
That geographic granularity — the fact that the guide distinguishes between a stretch upstream of one dam versus downstream of another — underscores how localized contamination can be. Two anglers fishing the same river on the same day might be subject to completely different advisories based on exactly where their lines hit the water.
Belleville Lake and the Huron River
Belleville Lake: Do not eat carp, catfish, gizzard shad, largemouth bass, smallmouth bass or suckers due to PFOs. That's a broad "Do Not Eat" list for a lake that sees heavy recreational use. The Huron River corridor tells an equally complicated story. Huron River (downstream of Ford Lake Dam to the river crossing on I-275): Do not eat carp, catfish, gizzard shad, largemouth bass, smallmouth bass or suckers due to PFOs. Further downstream, do not eat carp over 28 inches due to dioxins and PCBs, or rock bass due to PFOs.
The Clinton River
Clinton River (including the North Branch and Middle Branch of the Clinton River and the Red Run): Do not eat rock bass due to PFOs. The Clinton River system, which drains large portions of Oakland and Macomb counties before emptying into Lake St. Clair, has long been a recreational fishing corridor. The rock bass advisory here reflects broader PFOS contamination patterns across watersheds in the region.
Statewide Advisory Highlights: Beyond the Metro
The advisories extend far beyond southeastern Michigan. Across the state, several species carry consistent warnings that any Michigan angler should know. Do not eat carp due to PCBs — that warning appears in multiple bodies of water and reflects the bottom-feeding species' particular vulnerability to sediment-bound contaminants. Limit consumption of chinook salmon, coho salmon, freshwater drum, lake whitefish over 16 inches, largemouth bass, rainbow trout, smallmouth bass, steelhead, white (silver) bass, white perch and yellow perch due to PCBs.
Catfish — a popular sportfish and table fare across the state — carries a dual-chemical warning. Limit consumption of catfish due to dioxins and PCBs. And walleye, arguably Michigan's most prized eating fish, draws a three-contaminant advisory in some waters. Limit consumption of walleye due to dioxins, PCBs and PFOs. For the army of anglers who make a point of stocking their freezer with walleye fillets every fall, that's a warning worth taking seriously.
It's also worth noting some specific freshwater ponds and drains that carry "Do Not Eat" designations for species that might surprise anglers. Frank and Poet Drain: Do not eat bluegill or sunfish due to PFOs. Washago Pond: Do not eat bluegill or sunfish due to PFOs. Bluegill and sunfish are the gateway fish for many Michigan sportsmen — the species kids catch from docks, the fish that go into the first frying pan. Their appearance on "Do Not Eat" lists in certain locations is a reminder that no species is automatically safe simply because it's common or small.
How the Serving Size System Works
One of the guide's more practical features is its use of a standardized serving measurement. Eat Safe Fish guidelines are provided as MI Servings. One MI Serving for adults is 6-8 ounces of fish (about the size of an adult's hand). For children, one MI Serving is 2-4 ounces of fish (about the size of an adult's palm). The guide then assigns each tested species in each tested waterbody a monthly serving allowance, scaled to that definition.
Fish with eight MI Servings or more are considered the best choice to eat. Species that fall far below that number — or carry "Do Not Eat" designations — are at the other end of the risk spectrum. The Eat Safe Fish Guides include some species listed as "Do Not Eat," indicating that even one meal could lead to future health problems. Others are listed as "limited" and should only be eaten once or twice per year for healthy people and avoided entirely by people under age 15, people with health problems like cancer or diabetes, or people who are pregnant or breastfeeding.
The body-weight calibration of serving sizes is also worth understanding. For example, a 70-pound child's MI Serving size is 3 ounces of fish; a 110-pound person's MI Serving size is 5 ounces of fish. That scaling matters practically: a large adult male consuming a standard fish dinner is eating more total fish mass than a child eating the same "serving," and the guide accounts for that difference in chemical exposure calculations.
Who These Guidelines Are Built to Protect
The 2026 Eat Safe Fish Guides are not narrowly targeted at vulnerable populations, though they are specifically calibrated to protect those at the highest risk. The guidelines in the Eat Safe Fish Guides are set to be safe for everyone. This includes children, people who are pregnant or breastfeeding and people who have health problems, like cancer or diabetes. However, the guides are also for healthy adults who want to avoid getting too many chemicals in their bodies.
That inclusive framing is important. The state isn't issuing these advisories only as a message to sick people or mothers — they're a baseline for the entire fishing public. A healthy man in his thirties who fishes every weekend and eats his catch regularly is the kind of consistent, long-term consumer the guide is most relevant to, precisely because chronic low-level exposure to PCBs, PFOS, and dioxins builds over time. The absence of immediate symptoms is not a signal of safety.
The Buy Safe Fish Guide: For the Market and the Restaurant
The Eat Safe Fish program also addresses the growing overlap between recreational anglers and everyday fish consumers who source their meals from supermarkets or restaurants. The state also produces a Buy Safe Fish Guide to help residents choose seafood with lower levels of mercury when selecting fish at stores, fish markets or restaurants. That companion resource extends the program's reach beyond the waterway and into the grocery store, acknowledging that the average Michigan resident's exposure to fish-borne contaminants isn't limited to what he catches himself.
The Eat Safe Fish Guides are not laws or regulations. They provide free guidance to help people choose fish that are safe to eat and less likely to affect their health due to harmful chemicals. No one will cite you for keeping a walleye out of waters where consumption is advised against. But that voluntary framing shouldn't be read as a reason to dismiss the guidelines — it reflects the program's philosophy that informed choice is more effective than enforcement, and that the state's role is to give anglers the information they need rather than restrict their activity.
Areas of Concern: Michigan's Designated Hot Spots
There are 11 Areas of Concern (AOCs) caused by high levels of chemicals that need to be cleaned up. Those areas are also eligible for funding to help improve them. The AOC designation — a federal and state classification that identifies waterways with significant ecological and human health degradation — carries real consequences for fishing advisories. Waterways within AOCs tend to have more restrictive consumption guidelines and are subject to more intensive monitoring. The St. Clair River and St. Mary's River are among those listed. These are not obscure backwaters; they're major corridors of Great Lakes water movement that connect fishing communities across the region.
Importantly, according to the EPA, there is a group that has been delisted after a series of successful restoration efforts. That's worth noting not as cause for complacency but as evidence that remediation efforts do eventually move the needle — and that the bidirectional nature of the 2026 guideline changes (some more restrictive, some less) reflects real-world environmental progress and regression happening simultaneously across the state.
How to Use the Guide — And Where to Find It
The mechanics of using the guide are straightforward, though navigating 696 water bodies can be daunting if you don't know where to start. The guides break the state down into five regions — northeast, northwest, southeast, southwest and the Upper Peninsula — with a guide for each. An angler fishing the Muskegon River in the northwest is working from a different guide than one on the Rifle River in the northeast, and the specific advisories in those two documents may differ substantially for the same species.
The state has made access as frictionless as possible. Residents can visit Michigan.gov/EatSafeFish, or call the DHHS's Environmental Health Bureau at 800-648-6942, for more information on how to buy, eat and prepare safe fish. Physical copies of the guide are also available at no charge by calling the same number — a detail that matters for anglers who want something to keep in the tackle box or the glove compartment rather than navigating a website from the bank.
One practical note that often goes unmentioned: you do not need to wear gloves or worry about getting the chemicals on you. They will not absorb into your skin from the fish. Catch and release is almost always safe in Michigan regardless of where you're fishing. The chemical exposure the guide addresses is specifically through consumption of fish flesh — the danger is on the dinner plate, not at the end of the line.
The Bigger Picture: Great Lakes Water Quality and What It Means for Fishing Culture
Michigan's Eat Safe Fish program exists within a much larger story about the industrial legacy of the Great Lakes basin and the ongoing effort to reconcile that legacy with one of the most vibrant freshwater fishing cultures in the world. The lakes and rivers that produce trophy walleye, Great Lakes salmon runs, and some of the best bass fishing in the country are also the same waterways that received decades of industrial discharge, municipal waste, and chemical contamination. The 2026 guide is in many ways an annual accounting of how far that recovery has come — and how far it still has to go.
The fact that more than 90% of over 7,000 Michigan fish tested for consumption guidelines since routine PFAS monitoring began have shown some level of PFAS in the edible portion is a sobering baseline. It means that "some contamination" is effectively the norm for wild-caught freshwater fish in Michigan, and that the guide's function is to help anglers navigate degrees of risk rather than draw a clean line between safe and unsafe.
That nuance — degrees of risk, not binary danger — is central to how the program presents itself. "There are many health benefits to eating fish and the Eat Safe Fish Guides provide consumption recommendations based on the levels of certain chemicals found in fish in waterbodies across the state," said Natasha Bagdasarian, the state's chief medical executive. Fish remains a nutritionally valuable food, and the state is not in the business of telling people to stop eating it. The goal is informed consumption, not abstinence.
For Michigan anglers — weekend warriors, serious sportsmen, subsistence fishers who rely on their catch to supplement the grocery budget — the 2026 Eat Safe Fish Guides are the most complete public health tool available. Knowing which species to avoid, which to limit, and which are genuinely safe to eat regularly isn't just cautious health management. In a state with over 11,000 lakes, rivers, and streams, it's what it means to fish smart.
