Undeclared ingredients may cause life-threatening anaphylaxis in people with associated allergies.

Anaphylaxis requires prompt medical attention due to symptoms such as throat swelling, difficulty breathing, sudden drop in blood pressure, and loss of consciousness. Other symptoms of serious allergic reactions include rash, hives, itching, vomiting, diarrhea, and abdominal cramps.

About 6 percent of American adults and 8 percent of children have at least one food allergy, according to the U.S. Centers for Disease Control and Prevention (CDC).

Although fatal reactions are rare, concerns about undeclared allergens are a relatively common reason why companies choose to issue recalls. Contamination with dangerous pathogens is another common reason to issue a recall.

Listeriosis, an infection of Listeria monocytogenes, can cause serious symptoms, even in those who are otherwise healthy. About 260 of the estimated 1,600 annual cases are fatal, according to the CDC.

Most listeriosis infections are limited to the digestive system, with symptoms such as diarrhea and vomiting within 24 hours of eating contaminated food. But a more invasive form of the disease develops in some people within two weeks.

Symptoms of invasive disease include fever, muscle aches, headache, neck stiffness, confusion, loss of balance and seizures. About one in 20 people who contract the invasive form of listeriosis without being pregnant will die from it.

For those who are pregnant, symptoms are usually mild or nonexistent, but invasive disease “usually results in miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn,” according to the CDC.

E.coli usually causes unpleasant symptoms within three to four days after eating contaminated food. Symptoms may include dehydration, bloody diarrhea and abdominal cramps.

While most people recover from a E.coli Within a week, a rare type of kidney failure called hemolytic uremic syndrome can affect 5 to 10 percent of people infected with certain strains of the bacteria. Elderly people and children under 5 are particularly vulnerable.

Salmonella is the most common cause of food poisoning in the United States. Eating contaminated food can lead to an infection known as salmonellosis, which usually appears between six hours and six days after consumption. according to to the United States Food Safety and Inspection Service.

Cases of salmonellosis typically last four to seven days and include symptoms such as abdominal cramps, diarrhea and fever. Severe cases, which are more likely to occur in children, the elderly, or people with weakened immune systems, can include a range of other symptoms involving the joints and nervous system.
