More than 200 million eggs were recalled from supermarkets because they may have been contaminated with salmonella.
Salmonella infections sicken 1.2 million people in the US every year, leading to 23,000 hospitalizations and 450 deaths.
Infections are most common for young children. They’re most severe for infants, the elderly, and people with weakened immune systems.
Most cases resolve with rest and re-hydration after four to seven days, but some severe cases require antibiotics.
Every year in the US, about 1 million people get salmonella infections from food that’s been contaminated by one of the many kinds of Salmonella bacteria.
In the latest widespread incident, more than 200 million eggs have been recalled from supermarkets and grocery chains including Food Lion and Walmart. So far, at least 22 illnesses related to the contaminated eggs have been reported, according to the FDA.
Eggs and dairy products are one of the most common sources of the foodborne illness, but infections with salmonella — which cause an illness known as salmonellosis — also come from poultry, meat, unpasteurized milk, cheese, fruits, vegetables, spices, and nuts, among other things.
Recently, an outbreak linked to the herbal supplement kratom sickened at least 132 people in 38 states. Some people also get sick by interacting with animals, especially reptiles, amphibians, and birds.
How people get infected with salmonella and how the infection can be treated
According to the CDC, there are roughly 1.2 million cases of salmonella infections each year in the US. These cause an average of 23,000 annual hospitalizations and 450 deaths. Children — especially those under age 5 — are at the highest risk, and illness caused by these infections is most severe for infants, the elderly, and anyone with a weakened immune system.
When a person eats food that’s been contaminated with one of the 2,300 types of salmonella bacteria, they can get sick. The two most common types found in the US, Salmonella enteritidis and Salmonella typhimurium, account for about half of human infections.
The bacteria itself lives in the intestinal tract of animals. When animal feces contaminate meat, poultry, or dairy products, the bacteria spread. Cross-contamination can occur when produce or other foods come into contact with the bacteria.
Most people who get sick develop diarrhea, a fever, and abdominal cramps within 8 to 72 hours. Usually, people are sick for four to seven days. Most recover without treatment aside from rest and rehydration, though it can take several months for bowel movements to normalize.
In particularly severe cases, diarrhea can get bad enough that people need to be hospitalized. If the infection spreads from the intestines into the bloodstream, it can be fatal if not treated with antibiotics. A small number of cases can also cause joint pain from reactive arthritis, which can last for months or years.
How to prevent infection
Since salmonella infections can be so severe, food safety experts recommend taking a variety of steps to prevent infection.
