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

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.

Eating street food while traveling isn’t recommended, but there are ways to do it more safely

The US Centers for Disease Control and Prevention urge people to stay away from street food while traveling. But if you still want to eat it, the agency recommends making sure it’s cooked food and that it’s served steaming hot. Also, avoid eating any raw vegetables as they may be more likely to harbor pathogens.

Keep foods out of the temperature danger zone to help avoid sickness

This graphic can help remind you what temperatures are generally unsafe for perishable food because they can promote and encourage the growth of harmful pathogens.

Pooping or puking out pathogens is sometimes recommended with food poisoning

Sometimes stopping food poisoning-linked diarrhea with over-the-counter medications is a bad idea because it may prolong illness. Doctors can advise you if your diarrhea or vomiting is severe about what medications to take and when, but generally doctors recommend trying to stay hydrated during a bout of food poisoning and letting the body naturally remove pathogens from the body via vomiting or diarrhea, as needed.

Just because leftovers look and smell okay doesn’t mean they’re safe to eat

Despite what the sniff test is telling you, older leftovers should probably be trashed. Pathogens that cause illness don’t usually affect the taste, smell, or appearance of food (though if they look bad, you should chuck them as well). Scientists recommend tossing leftovers within a few days even if they appear to be fine.

A brief explainer on food expiration dates and what they really mean

Roughly 20% of food items in the US are thrown out because consumers don't understand how to interpret expiration labels. Over time, when supermarkets began carrying processed foods, grocers use packaging codes to track how long foods had been on...

Cantaloupe’s textured skin boosts the risk of food poisoning

Food safety expert Darin Wetwiler says he prefers to stay clear of this fruit altogether since it’s so hard to keep the textured skin pathogen-free. He advises trying to avoid pre-cut cantaloupe in particular, since consumers won’t know when the fruit was sliced and pathogens on the outside could have been spread to the part we consume during slicing and multiplied.

Gas station sushi is actually pretty safe to eat, experts say

Vending machine food, in general, gets a bad rap for its seeming lack of freshness, but whether the food you eat is safe usually depends on the quality of the cold chain supply logistics that brought it to the point of sale. Most prepackaged sushi fish has been flash frozen, and the rice has been mixed with vinegar to inhibit bacteria.

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."

Tips for reducing the risk of antimicrobial resistance

Antimicrobial resistance is bad news. But there are lots of things you can do to both protect yourself from superbugs and help keep the problem of antimicrobial resistance from getting worse. This page from the CDC offers clear, straightforward guidelines that can help keep you—and your loved ones—healthy.

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.

HFMD can survive on surfaces for days at a time

That's why the virus can be transmitted via fomites—surfaces that have virus on them like doorknobs, kids toys, etc. These viruses are resilient—they are often even resistant to freezing (and are frequently stored at freezing temperatures in lab settings).

The history of many kitchen appliances involves unexpected discoveries and applications, including wartime radar turned hamster defroster and replacing an 'ice king' with heat-stealing boxes.

How spoiled meat helped uncover a bacterium that can survive the vacuum of space

When a can of ground beef and pork spoiled despite attempts to sterilize it with gamma radiation, researcher Arthur Anderson isolated the bacteria in the food and discovered Deinococcus radiodurans. The polyextremophile has since been found on the walls of nuclear reactors and overcomes radiation damage through highly optimized DNA repair mechanisms.

Freezer burn is the result of moisture leaving ice cream

The ice cream death knell occurs when water crystals melt and then refreeze on the surface of the treat, creating a crunchy (but far from delectable) shell. The best way to prevent this unfortunate outcome is by storing your ice cream in a freezer that’s colder than 0°F.

How understanding a balanced diet can help you make good food choices

Microplastics are entering human food chains through fertilized farmland

Microplastics from sewage sludge used as fertilizer contaminate agricultural soil and eventually enter our bodies through the food supply of carrots, wheat, and other foodstuffs. In Europe, farmland may absorb up to 710 trillion microplastic particles yearly.

The FDA does not approve dietary supplements before they go to market

The US Food and Drug Administration does not regulate products including vitamins, probiotics, and herbal mixes as drugs due to the Dietary Supplement Health and Education Act of 1994, which amended the Federal Food, Drug, and Cosmetic Act. Because dietary supplements are regulated as a subcategory of foods, inspectors do not assess whether dietary supplements work as advertised before sale.

The benefits of sous vide: cooking food in bags immersed in water

Through this technique, food can be prepared to precise temperatures lower than those of open flames, without the risk of overcooking, with less oil, fat, and salt, and without requiring ongoing attention. By allowing for long cooking times, tougher cuts of meat can also be prepared at lower temperatures.

How to avoid a 'bad trip' advice includes relaxing your mind if you experience scary things and not fighting the feeling

He tackles how psychedelics work, explains microdosing and psychedelic risks, how the substances could be used to treat addiction, and the history of psychedelic stigma.

Stainless steel and cast-iron pans should be used over older nonstick cookware

Although modern nonstick pans avoid forever chemicals like PFOA, they were previously used in the manufacturing of Teflon coatings and have been linked with certain types of cancer, infertility, and other adverse health outcomes. Vintage plastic utensils should also be avoided due to the leeching of contaminants in early formulations of plastic.

Tooth brushing immediately after vomiting rubs in corrosive acid, damaging teeth

Brushing right after vomiting can further erode the enamel by rubbing in stomach acid and etching it onto tooth surfaces. Instead, research suggests you should consider rinsing your mouth with water and baking soda in the short-term and waiting to brush your teeth for 30-60 minutes.

Unlike fruits, the category of 'vegetables' is a culinary term, not a scientific one

Within botany, fruits are defined as the ripened ovaries of flowering plants, and include apples, grapes, tomatoes, avocados, green beans, peppers, and almonds. In the kitchen, "vegetables" is an umbrella term that encompasses many fruits and other parts of plants, such as leaves (lettuce, kale) and roots (carrots, beets).
