The health authorities in the United States have helped in increasing the level of awareness regarding the recent food safety threat related to the possible presence of norovirus in oysters and clams. The United States Food and Drug Administration (FDA), along with other agencies in the country, has issued alerts and recalls related to oysters and clams that are distributed in various states in America.
A Multi-State Recall Raises Alarm
The FDA has recently announced the recall of raw oysters and Manila clams that were harvested from waters in Washington state and could possibly be infected with the norovirus and distributed to nine states, including Arizona, California, Florida, Georgia, Illinois, Nevada, New York, Oregon, and Washington.
The raw oysters and clams were picked up from the waters between February 13 and March 3, 2026, and it is possible that some of these raw oysters and clams could have already been consumed prior to the recall being announced by the FDA. The raw oysters and clams could possibly look and smell normal and could possibly be difficult to identify as hazardous prior to consumption.
Illinois is one of the states that could possibly be affected by the recall announced by the FDA, and health officials in the Midwest are taking the recent recall of raw oysters and clams seriously and are urging Illinois residents to be careful when it comes to the consumption of raw oysters and clams.
What Is Norovirus?
Norovirus is also known as the “stomach flu.” However, it has nothing to do with the flu. The disease is characterized by inflammation of the stomach and intestines and is highly contagious through infected food, surfaces, and contact with infected persons.
The signs and symptoms of the disease start 12 to 48 hours after the onset of illness and can cause vomiting, diarrhea, nausea, stomachache, fever, headaches, and body aches. The illness can take a day or two to recover from, but in some cases, it can cause serious illness in young children, the elderly, and those with weak immune systems.
According to health authorities, it is difficult to fight the norovirus because it only requires a small amount of the virus to make people ill. In addition, people who are infected with the virus are capable of spreading it before they are ill and even after they are no longer ill.

Both oysters and clams are referred to as “filter feeders,” which means they take in huge amounts of water to get nutrition. Although this is beneficial in maintaining cleanliness in the waters, it is also through this process that the oysters and clams are able to pick up disease-causing pathogens if the waters are polluted.
If polluted waste is dumped in the waters, the viruses are picked up by the oysters and clams and remain in the meat until it is consumed. If people eat the meat raw, they are ingesting the viruses directly.
According to health experts, it is not uncommon for illness to occur as a result of eating oysters and clams. In previous cases, hundreds of people have been affected after ingesting infected oysters, and as a result, the oysters are recalled and health officials investigate the incident.
Recent Cases and Investigations
In addition to this recall case, past studies have established that norovirus infection can be associated with the consumption of raw oysters, especially if they come from certain areas along the coast. For example, this year, cases of norovirus infection have been reported by health authorities in the state of Washington due to the consumption of oysters from a certain harvest area in British Columbia.
These cases form part of the reasons for the general warning about contaminated food, and authorities are currently tracing the chain to ascertain whether more food is implicated.
In other areas in the country, for example, in the Midwest region, authorities have been warning residents about cases of norovirus infection in general because they have been on the increase in recent months.
What Consumers Should Do
Some of the precautions that can be observed in order to avoid the infection include:
• Don’t eat raw oysters and clams unless they are obtained from a safe source.
• Cook the oysters and clams since they can be destroyed by heat.
• Wash hands frequently, especially before handling food.
• Sanitize kitchen surfaces if they were used in preparing the infected food.
• If infected with the disease, people are encouraged to seek medical attention and report the infection.
Restaurants and stores are asked to sanitize the kitchen surfaces in order to avoid the infection if the infected food has been handled before.
A Reminder About Food Safety
Based on the information provided by the experts in the food safety sector, it is a great reminder of the importance of monitoring in the seafood industry. Although the US has very strict laws regarding the farming and harvesting of these types of foods, they can still be contaminated for a number of reasons, including environmental issues.
Although the investigation is still underway, it is important to point out that the FDA and the health sector will continue to inform the public about the situation in the event of recalls and the number of people falling victim to the contaminated foods. However, they have stated that the public is still safe as long as they follow the guidelines provided by the FDA.
Although the investigation is still underway, it is important to point out that the recall is a great reminder of the importance of monitoring in the seafood industry, even for foods as exclusive as oysters and clams.
