1 in 6 Americans get food poisoning each year

Foodborne illnesses cost our country an estimated $74.7 billion in 2023

A US government estimate puts the cost of all foodborne illness in 2023 at almost $75 billion dollars. In a report published by the US Department of Agriculture’s Economic Research Service, government analysts detailed how the burden of foodborne illness includes medical costs, but also more hidden costs like lost wages. The analysis also breaks down estimated costs by pathogen.

Restaurants are where most of us contract food poisoning in the US

From 2014 to 2022, most reported foodborne illness cases occurred at restaurants. Between 2020 and 2022—when COVID-19 also likely influenced restaurant eating habits and tracking—there were only 238 foodborne illness outbreaks linked to restaurants, down from 714 the prior two years. Still, restaurants were behind most reported outbreak cases. (Some readers may experience a paywall.)

Severe cases of food poisoning have doubled even as food recalls dropped

Food recalls were down in 2024 by 5% as compared to 2023. But some researchers suspect that’s just because there were fewer inspections or fewer people reporting illnesses: Hospitalizations from food poisoning more than doubled during that same period, from 230 to 487, and deaths rose from 8 to 19.

Food poisoning investigations have led to more than 1 billion pounds of food recalls

PulseNet is the US government’s real-time foodborne illness tracking system for leading causes of food poisoning. There, a network of labs and scientists share DNA sequences for pathogens collected from contaminated food and also from sickened individuals, looking for patterns in the pathogens’ genome sequences that will help them hopefully finger a certain food, warehouse, producer, or restaurant.

Food poisoning can sometimes cause serious long-term health issues

Although foodborne illness can be relatively mild and cause short-term discomfort, more rarely it can also cause long-term severe health consequences, depending on your individual risk factors, the severity of your sickness, and the care you receive. Kidney failure is one serious complication associated with certain types of food poisoning. Meningitis, hepatitis, arthritis, and pancreatitis are also rare and serious foodborne illness complications. If a pregnant person gets food poisoning, it can cause health issues for the fetus.

Norovirus is the leading cause of food poisoning in the US

The illness is typically transmitted when virus-laden feces gets into another person’s mouth. That occurs when people do not properly wash their hands, contaminating food or surfaces.

Climate shifts are projected to cause more cases of food poisoning

Research published in 2024 suggests that with more severe heatwaves and natural disasters, scientists expect there to be a rise in foodborne disease, especially in Africa and Asia. Already, there are an estimated 600 million food poisoning cases and 420,000 deaths annually. Diarrhea is the most common cause of those deaths.

We can get food poisoning from spending time in swimming pools, lakes, rivers, and ponds

Some of the same pathogens that may sicken us in food or water may also sicken us in recreational swimming environments. Bacteria can rub off of people’s (or animal’s) bodies or contaminate the water through a diarrheal episode. Washing your hands for at least 20 seconds before eating food if you are at the beach, pool, or other similar environments and being sure not to swallow the water are ways to help keep safe.

Swimmer's ear is America's most common waterborne illness

Federal government analysis of the roughly 7 million waterborne illness cases that occur annually in the US found that swimmer's ear comprises some 4.7 million, or 65%, of the annual waterborne illnesses and 20% of hospitalizations. Norovirus infection comes in second place.

Mycotoxins are toxic compounds produced by fungi—some show up in food

About a quarter of the world’s agricultural products are contaminated with mycotoxins. Some of these compounds can cause serious health problems, including cancer, so the US government has set up monitoring programs to detect them in our food and in animal feed. Humans can become ill if they eat contaminated food, but also if they ingest products from animals that had previously consumed these toxic compounds, such as milk from a cow that ate contaminated corn.

More than 20 mosquito-borne and tick-borne diseases are found in the US

Children, older adults, and people with compromised immune systems are at particular risk of poorer health outcomes from these diseases. But dog owners and outdoor enthusiasts are among those at particular risk of contracting these illnesses, which include Lyme disease, Zika, and the condition Alpha-gal Syndrome.

Foods shouldn't be defrosted on the counter, but microwaving to defrost is okay

This wide-ranging video from the US Food and Drug Administration explains causes of food poisoning and tips for consumers. The agency's advice includes that we should separate meat and eggs from our veggies and fruits in our shopping carts, during food prep, and in the fridge (with meat located below veggies in the refrigerator in case it drips).

Americans throw away nearly 40% of their food supply

The US discards roughly 63 million tons of food per year, making it one of the largest contributors to landfill waste. Food scrap waste is the single largest category of material sent to landfills.

The science of food allergies

Why do certain substances trigger an immune response while others don't? Listen to researchers explain the science in this five-minute video. Food allergies affect around 8% of children and 2% of adults in the US, and—unlike sensitivity or intolerance—they involve the immune system mistaking certain harmless proteins in foods as dangerous invaders, triggering a rapid and sometimes severe defense response.

In the 19th century, ice-cream-related illnesses were somewhat regular in America

Ice cream was a popular dessert, but it was also a dangerous one, with numerous reports of vomiting, diarrhea, and—in some cases—death. Historians argue this was likely due to vendors' poor hygienic practices.

11 people died from firework injuries in the US in 2024

Most of those deaths involved misuse of the explosives and device malfunctions or misfires. That fatality count doesn't include the almost 15,000 people who received treatment in the emergency room due to firework-related injuries. More than a third of all the injuries in 2024 were burns, underscoring the risks of using these explosive devices.

Up to 225 cases of leprosy in the US are diagnosed each year

Most cases in the US are imported, meaning someone was infected in a country where it was more common. Since symptoms can sometimes take decades to appear, tracing the origin of the disease can be hard.

Sepsis is the leading cause of death in hospitals

Sepsis is the result of an overly aggressive immune system trying to combat infection, triggering inflammation throughout the body. After it begins, each passing hour increases the risk of death by 4% to 9%, and an estimated 350,000 people die from the condition in the US each year.

Visualizing obesity rates across the US

Nearly 70% of adults in the US are either overweight or obese, rates that have tripled over the last 60 years. Severe cases have risen tenfold during this period. Factors like location, income level, and demographics contribute to various obesity levels across the US. Visualize the statistics with this article and chart series.

Vitamin D supplement pills are linked to rising cases of vitamin D toxicity in the US

Vitamin D deficiency is common. But taking Vitamin D supplements in doses exceeding 4,000 IU/day (a measurement of vitamin biological activity) for prolonged periods can raise bodily concentrations of this vitamin to dangerous values. US National Poison Data indicates that the annual average of vitamin D poisonings from 2000-05 was 196, but this rose by 1,600% to 4,535 per year for the period of 2005-11.

How many Americans receive government assistance?

In 2022, nearly half of all American children—and roughly one in three Americans overall—were enrolled in at least one government assistance program. Those programs provide support for people who cannot afford healthcare, food, housing, or other needs. Find out more about the number of Americans receiving government assistance here.
