What to know about the FDA's paralytic shellfish poisoning warning
- The U.S. Food and Drug Administration says consumers should avoid eating shellfish from Oregon and Washington state as they may be contaminated with toxins that cause paralytic shellfish poisoning.
- Oregon and Washington have prohibited shellfish harvesting on their coastlines, but shellfish have already been distributed across the country.
- At least 31 people have been sickened by paralytic shellfish poisoning so far.
The U.S. Food and Drug Administration says consumers should avoid eating shellfish from Oregon and Washington state as they may be contaminated with toxins that cause paralytic shellfish poisoning. At least 31 people have been sickened in Oregon so far, according to state health officials. Here’s what to know about the federal agency’s advisory.
What did the FDA say about shellfish?
The warning says to avoid oysters and bay clams harvested from Netarts and Tillamook bays in northern Oregon since May 28, as well as shellfish harvested from areas around Willapa Bay in southern Washington since May 26. They may be contaminated with high levels of paralytic shellfish poisoning, or PSP, a naturally occurring toxin produced by algae.
Shellfish harvested from those areas during that period were distributed beyond Oregon and Washington to Arizona, California, Colorado, Hawaii, Nevada, New York. The FDA has warned restaurants and retailers in those states not to serve it.

What do we know about the shellfish poisoning outbreak so far?
Elevated levels of toxins were first detected in shellfish on the Oregon coast on May 17, state fish and wildlife officials said.
Since then, a paralytic shellfish poisoning outbreak has sickened at least 31 people in Oregon, according to the Oregon Health Authority. The agency has asked people who have harvested or eaten Oregon shellfish since May 13 to fill out a survey intended to help investigators identify the cause of the outbreak and the number of people sickened.
Oregon authorities have closed the state’s entire coastline to the harvesting of mussels, razor clams and bay clams. Agriculture officials have also closed three bays, including those named in the FDA advisory, to commercial oyster harvesting.

Officials in neighboring Washington have also closed the state’s Pacific coastline to the harvesting of shellfish, including mussels, clams, scallops and oysters, a a shellfish safety map produced by the Washington State Department of Health shows.
What is paralytic shellfish poisoning?
Paralytic shellfish poisoning, or PSP, is caused by saxitoxin, a naturally occurring toxin that’s produced by algae. Saxitoxin is a neurotoxin, meaning it can damage nerve tissue.
People who eat shellfish contaminated with high levels of saxitoxins usually start feeling ill within 30 to 60 minutes, according to Oregon health officials. Symptoms include numbness of the mouth and lips, vomiting, diarrhea, shortness of breath and irregular heartbeat in severe cases.
There is no antidote to PSP, according to the health agency. Treatment for severe cases may require mechanical ventilators to help with breathing.
Authorities warn that cooking or freezing contaminated shellfish doesn’t kill the toxins or make it safe to eat.
What causes paralytic shellfish poisoning?
A “very large” algal bloom has resulted in “unprecedented levels” of PSP toxins along Oregon’s coast, Matthew Hunter, shellfish program manager for the Oregon Department of Fish and Wildlife, said during a briefing.
The toxins have accumulated in the shellfish, sickening some people who have eaten them.
While the factors that create harmful algal blooms are not well understood, certain factors — resulting from both natural processes and human activities — are believed to play a role, according to the National Oceanic and Atmospheric Administration.
“Studies show that many algal species flourish when wind and water currents are favorable,” the agency says on a webpage dedicated to explaining harmful algal blooms. Some blooms, it says, stem from “sluggish water circulation, unusually high water temperatures, and extreme weather events like hurricanes, floods, and drought.”
Algae growth can also increase when nutrients used in fertilizers, mainly phosphorus and nitrogen, flow into bodies of water, according to the agency.
How long will shellfish be unsafe to eat?
Oregon officials said it may take weeks, months or even up to a year for toxin levels to subside, depending on the type of shellfish.
Mussels can accumulate paralytic shellfish poison rapidly, but also rid themselves of it quickly, according to Hunter, the Oregon fish and wildlife official. Because of this, it may take anywhere from two weeks to a month for mussels to eliminate the toxin.
Razor clams, however, are slower to do so. It may take them several months to a year to cleanse themselves due to the current high levels of toxin, Hunter said.
How common is paralytic shellfish poisoning?
Such high levels of paralytic shellfish poison haven’t been detected in Oregon in decades, according to Hunter, who cited a previous shellfish harvesting closure in the state in 1992.
However, PSP has been prevalent in the regional waters for centuries, he said.
What’s the economic impact of the outbreak?
The harvesting closures may deal a blow to Pacific Northwest fisheries.
The shellfish industry generates $270 million each year for the region’s economy, according to the National Oceanic and Atmospheric Administration, and employs some 3,200 people.

The latest COVID-19 vaccine (2024-2025) has been linked to fewer serious heart-related events among U.S. veterans.
New research confirmed a small reduction in COVID-related cardiovascular events, or COVID-19-associated MACE, due to the vaccine.
MACE (major adverse cardiovascular events) is a composite measure of serious heart-related outcomes. It typically includes cardiovascular death, heart attack and stroke, and may also include hospitalization for heart failure.
VACCINES FOR FLU AND COVID: SHOULD YOU GET BOTH AT THE SAME TIME?
Using health records from the U.S. Department of Veterans Affairs, the researchers compared two groups of veterans — one that received the COVID and flu vaccine on the same day (nearly 350,000 people) and another group that received only the flu vaccine (nearly 700,000 people).
For people older than 75, vaccine effectiveness against COVID-associated MACE was 50.7%. (iStock)
Out of more than one million veterans studied, the average age was about 70 and 92% were male, according to a press release.
Within about eight months, the results showed that those who received the 2024-2025 COVID vaccine had a lower risk of COVID-associated major cardiovascular events, with a relative vaccine effectiveness of 37.7%.
The COVID vaccine was linked to a 57.9% lower risk of cardiovascular death, 38.5% lower risk of heart attack and 41.9% lower risk of hospitalization for heart failure, the researchers stated. The result for stroke was not statistically significant.

The benefit was greatest among adults ages 75 and older and those with underlying health conditions. In people over 75, the vaccine was 50.7% effective at preventing COVID-associated MACE.
As the study was observational, it could not prove cause and effect between the COVID-19 vaccine and lower risk of cardiovascular events, but only highlighted an association.

Dr. Glenn Hirsch, cardiologist at National Jewish Health in Denver, Colorado, called these results “not overall surprising” in an interview with Fox News Digital.

“This result is consistent with previous studies of the COVID-19 vaccine and other vaccines against infectious diseases [in] preventing cardiovascular events, including heart attack, cardiovascular cause of death or hospitalizations,” he said.
Acute inflammation in the body from infections like COVID-19 increases the risk of cardiovascular events and can cause further complications, according to the doctor.

“This can lead to a higher risk of blood clotting, but can also make arterial plaques susceptible to rupture, which then leads to clot formation to heal a ruptured plaque,” he said. “This clotting can cause a near-total or complete occlusion of an artery, leading to these cardiovascular events.”
“Vaccines either prevent infection or reduce the severity of infection and subsequent inflammation, lowering the cardiovascular risk.”

Despite the positive outcome, the overall benefit of the vaccine in this study was less than in previous studies, according to Hirsch, who was not involved in the research.
This could be due to the lower severity of illness seen in more recent COVID-19 variants, as well as immunity from prior infections among unvaccinated people, he noted. There has also been a decline in COVID testing, making it more difficult to link cardiovascular events to the virus.

“The bottom line [is] that there is still evidence of benefit from COVID-19 vaccination like many other infectious disease vaccinations, and people should be encouraged to discuss these with their healthcare team annually,” Hirsch advised.

“This is an observational trial and there can always be some confounding after necessary statistical adjustments and other potential benefits or harms, including adverse effects from vaccines that were not investigated in this study,” he added.

A former “Real Housewives of Beverly Hills” star is speaking out about a fresh wave of health issues.
Brandi Glanville, 53, has been speaking publicly about ongoing swelling, lumps and paralysis of her face since 2023.
At the time, the reality star shared that she believed she had been infected with a parasite during a trip to Morocco, Fox News Digital previously reported.

Glanville was first diagnosed with stress-induced angioedema, a sudden swelling of the deeper layers of the skin and mucous membranes, according to Cleveland Clinic.
Angioedema “is a reaction similar to hives that affects deeper layers of the skin. It can appear with hives or alone,” Mayo Clinic states.

Most recently, in a June 18 episode of her podcast “Brandi Glanville Unfiltered,” Glanville revealed that doctors discovered a “benign tumor” in one of her facial lymph nodes.
The reality star, who has previously speculated that a parasite may be contributing to her facial symptoms, said the finding could help explain the swelling and fluid buildup she has experienced and noted that she has had a lump in her face for “years.”

“It could be why the fluid is going around my face and why I’m having a hard time,” she added.
While benign tumors of the face have been known to arise from fat tissue, blood vessels, skin structures, salivary glands or lymphatic tissue, Glanville has not publicly disclosed the specific type of diagnosis she received.
