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

1 in 6 Americans get food poisoning each year

The US federal government estimates there are about 48 million cases of foodborne illness in the country annually, resulting in as many as 3,000 deaths and 128,000 hospitalizations. Food poisoning puts those with weakened immune systems, the elderly, pregnant people, and young children at particularly high risk. This chart of common disease-causing pathogens highlights common threats and details about them, including likely food sources.

Reporting food poisoning aids in limiting outbreaks

If you suspect you were sickened by meat or poultry or by other food products (or your pet was sickened), the US has different voluntary online reporting forms and hotlines you can call. There’s even one for concerns about potentially contaminated pet food products. If you were potentially sickened at a restaurant, however, you report that directly to state and local health departments, not the federal government.

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 companies usually issue recalls voluntarily and you can be automatically notified about them

Protecting yourself from food poisoning means staying on top of food recall announcements. Notices about these from the US government, which you can automatically receive after signing up at this link, note what products have been recalled by food companies. Companies alert the US Food and Drug Administration or the US Department of Agriculture when they issue recalls so the public can stay informed.

Lengthy incubation periods are why it’s tough to link foodborne illness to specific foods

People may not get sick from a foodborne pathogen for several days after consuming it, making it a challenge to link the illness and its cause. Factors influencing when a person starts feeling sick—even as the pathogen is multiplying in the gut—include individual variations in immune systems and gut microbiomes, what other foods are in the person’s body, and how much of the pathogen was consumed.

At the beginning of the 20th century, a group of young men ate standard American food—replete with food additives like borax and formaldehyde—as part of government research to better understand food safety.

Listen to how the 1902 'poison squad' experiments changed food safety in America

As part of government research, a group of young men were paid to eat standard American food—replete with food additives like borax and formaldehyde—which revealed the dangers of unregulated food. The work was led by the first FDA commissioner, Harvey Wiley, who helped end the "century of the great stomachache."

Natural toxins produced on plants or consumed by animals may cause food poisoning

When humans eat plants with certain natural toxins on them—including a family of toxins called aflatoxins that fungi produce on crops like peanuts and corn— they can become ill with food poisoning. Toxins can still harm humans even if animals or plants appear fine to the human eye. The World Health Organization advises that we should throw away moldy or discolored foods, refrain from eating wild plants or mushrooms that aren’t definitively nonpoisonous, and remember that just because something is “natural” it’s not always safe to eat.

How uploading your consumer genetic testing could lead to a distant relative's arrest

This podcast includes a discussion about how law enforcement can compare DNA samples from a crime scene against voluntarily uploaded DNA on consumer genealogy databases to close cases. Investigators can and have cross-referenced a suspect's crime scene DNA with that of a suspect's relatives who happened to have chosen to upload their genetic information to an open-source genealogy database.

Trader Joe's isn't a public company, so it doesn't have to disclose its suppliers

However, when a product is recalled, the US FDA reveals the manufacturer. Business Insider dug into Trader Joe's recalled product history to figure out who is making its food. As it turns out, it's a multitude of suppliers, including big companies that make food for other grocers, such as PepsiCo's Naked Juice and Conagra.

Explore how close you live to some of the most contaminated places in the US

Known as Superfund sites, these toxic locations undergo long-term cleanup to remove hazardous waste, protect health, and restore land for safe reuse. As of 2025, the EPA lists around 1,300 active Superfund sites on its National Priorities List, with more than 450 cleaned and removed since 1980.

Lyme disease-causing bacteria predate any suspected biological weapons testing

Borrelia bacteria existed long before any US biological weapons program—or human presence in North America. One study comparing genomes of the bacteria behind Lyme disease collected samples of the bacteria over three decades and calculated that the bacterium has been in North America longer than humans, at least 60,000 years. Other work found related bacteria preserved in amber from millions of years ago.

ConsumerLab is a watchdog site reviewing supplements for quality and recalls

The group purchases supplements and tests them for accuracy. When it tested 26 popular B vitamin supplements, it found five failed their tests because they provide either significantly less or much more of the ingredients than listed. This type of product-label mismatch can occur because the FDA does not regulate these products as it would a drug.

The US FDA issued a 2025 warning about BPC-157 and other popular peptides

BPC-157, which mimics a naturally occurring gut peptide involved in soft tissue repair, has been marketed for various regenerative properties. But the FDA warned in July 2025 that it doesn't have enough data to assess its safety in humans and that such products may also pose risks related to contamination.

Trudging through the dark web to expose child abuse

A computer expert who created a system to track down sources of revenge porn and an investigative journalist joined forces to investigate digital abuse. Their investigations focused on so-called clear nets, websites that make up the web most users surf. Then, they turned their investigation toward the dark web, where they found a child abuse website with more than 1 million registered users.

Fecal transplants can help treat infections

Fecal transplants aim to transplant healthy gut bacteria into ill patients by transferring (literally) samples of human waste from a healthy patient to a sick patient. The technique has been shown to cure otherwise deadly Clostridioides difficile (C. diff) infections and is being studied for a range of other uses.

The process provides affordable, on-site, real-time monitoring of fermentation quality.

Pizza Hut helped pioneer online food delivery

The company's PizzaNet website launched in 1994, allowing users to order pizza online for the first time. The service launched in select areas of Santa Cruz, California, though its servers were located in Kansas.
