Sprouts: What You Should Know
Eating raw sprouts may lead to foodborne illness, especially in susceptible individuals.
Nuts, grains, beans, and other legumes, and their by-products, are found in a wide variety of foods. Since these foods are ingredients in so many food products, contamination or mislabeling of allergens can pose a widespread risk.
Contamination may come from harmful bacteria such as salmonella, some foods in these categories, particularly grains, are also susceptible to chemical environmental risks.
Several of these foods – including tree nuts, peanuts, wheat, and soybeans – have been classified as major food allergens by the U.S. Food and Drug Administration. The law requires that all foods are labeled with their ingredients, and that labels clearly identify any of the major food allergens or their protein derivatives.

People often understand that it is dangerous to eat raw eggs because of the risk of Salmonella, but eggs aren’t the only potential carrier of foodborne illness in raw dough or batter. Raw flour may be contaminated with harmful bacteria such as E. coli.
Flour can be made from a variety of grains, nuts, and legumes including wheat, soy, tree nuts, and peanuts, all four of which the U.S. Food and Drug Administration classifies as major food allergens. Manufacturers are legally required to list ingredients and clearly identify any major allergens (or their protein derivatives) on the labels of food products.
Infants and young children are particularly vulnerable to foodborne illness because their immune systems are not developed enough to fight off infections. That's why extra care should be taken when handling and preparing their food and formula.
The most important action that you can take to prevent foodborne illness in your babies and children is to wash your hands. Your hands can pick up harmful bacteria from pets, raw foods (meat, poultry, seafood, eggs), soil, and diapers.
Always wash your hands:

Do’s and don’ts for feeding your baby, plus tips on microwaving baby food and when to call the doctor.
If you’re the parent or caretaker of an infant, you’ve probably heard that breast milk is the best source of nutrition for infants. In situations in which it’s not possible to breastfeed an infant, you may choose to use a commercially prepared infant formula.
Why can’t I give my baby cow’s milk?
Cow's milk by itself is not appropriate for infants less than 1 year old. Cow’s milk does not have the correct balance of nutrients for infants to grow and develop normally, and it can cause problems with anemia and kidney function.
Raw milk is never appropriate for infants – or anyone else. It should not be consumed by anyone at any time for any purpose. Raw milk can harbor dangerous microorganisms, such as Salmonella, E. coli, and Listeria, that can pose serious health risks.
But isn’t formula made from cow’s milk?
Most infant formula is made with cow's milk, but it has been modified and supplemented with additional nutrients. As a result, the formula is more nutritious and easier for the baby to digest than cow’s milk. Other formula options include soy-based formulas and hypoallergenic (or protein hydrolysate and amino acid-based) formulas. Special formulas are available for babies who are premature or have other health problems.
How does the government regulate infant formula?
The FDA does not approve infant formulas before they can be marketed. All formulas marketed in the United States, however, must meet Federal nutrient requirements. The FDA also monitors infant formula, which means that it inspects facilities that manufacture formula and analyzes samples.
What can I do to make sure that formula is safe for my baby?
Here are a few basic steps that you can follow to ensure that formula is safe from bacteria that can cause illness.

Many people don’t realize that the basic principles of food safety apply to their pets’ foods too. For example, pet food or treats contaminated with Salmonella can cause infections in dogs and cats. And contaminated pet food that is not handled properly can cause serious illness in people too, especially children.
If you’re a pet owner, one of the most important things you can do to keep your pets, your family, and yourself safe from foodborne illness is to wash your hands:

Food Poisoning Symptoms-CDC
If you believe you or someone you know got sick from food, even if you don’t know what food it was, please report it to your local health department. Reporting your illness may help public health officials identify a foodborne disease outbreak and keep others from getting sick.
Food poisoning symptoms may range from mild to severe and may differ depending on the germ you swallowed. The most common symptoms of food poisoning are:
After you consume a contaminated food or drink, it may take hours or days before you develop symptoms.
Most people have only mild illnesses, lasting a few hours to several days. However, some people need to be hospitalized, and some illnesses result in long-term health problems or even death. Infections transmitted by food can result in chronic arthritis, brain and nerve damage, and hemolytic uremic syndrome (HUS), which causes kidney failure.
If you experience symptoms of food poisoning, such as diarrhea or vomiting, drink plenty of fluids to prevent dehydration.
See your doctor or healthcare provider if you have symptoms that are severe, including:
Germ and Typical Time for Symptoms to Appear | Typical Signs and Symptoms | Common Food Sources |
---|---|---|
Campylobacter 2 – 5 days |
Diarrhea (often bloody), stomach cramps/pain, fever | Raw or undercooked poultry, raw (unpasteurized) milk, and contaminated water |
Clostridium botulinum (Botulism) 18 – 36 hours |
Double or blurred vision, drooping eyelids, slurred speech. Difficulty swallowing, breathing and dry mouth. Muscle weakness and paralysis. Symptoms start in the head and move down as severity increases | Improperly canned or fermented foods, usually homemade. Prison-made illicit alcohol. |
Clostridium perfringens 6 – 24 hours |
Diarrhea, stomach cramps. Vomiting and fever are uncommon. Usually begins suddenly and lasts for less than 24 hours | Beef or poultry, especially large roasts; gravies; dried or precooked foods |
Cyclospora 1 week |
Watery diarrhea, loss of appetite and weight loss. Stomach cramps/pain, bloating, increased gas, nausea, and fatigue. | Raw fruits or vegetables, and herbs |
Escherichia coli (E. coli) 3 – 4 days |
Severe stomach cramps, diarrhea (often bloody), and vomiting. Around 5-10% of people diagnosed with this infection develop a life-threatening complication. | Raw or undercooked ground beef, raw (unpasteurized) milk and juice, raw vegetables (such as lettuce), and raw sprouts, contaminated water |
Listeria 1 – 4 weeks |
Pregnant women typically experience fever and other flu-like symptoms, such as fatigue and muscle aches. Infections during pregnancy can lead to serious illness or even death in newborns. Other people (most often older adults): headache, stiff neck, confusion, loss of balance and convulsions in addition to fever and muscle aches. |
Queso fresco and other soft cheeses, raw sprouts, melons, hotdogs, pâtés, deli meats, smoked seafood, and raw (unpasteurized) milk. |
Norovirus 12 – 48 hours |
Diarrhea, nausea/stomach pain, vomiting | Infected person, contaminated food like leafy greens, fresh fruits, shellfish (such as oysters), or water, or by touching contaminated surfaces |
Salmonella 12 – 72 hours |
Diarrhea, fever, stomach cramps, vomiting | Eggs, raw or undercooked poultry or meat, unpasteurized milk or juice, cheese, raw fruits and vegetables |
Staphylococcus aureus (Staph) 30 minutes – 6 hours |
Nausea, vomiting, and stomach cramps. Most people also have diarrhea. | Foods that are not cooked after handling, such as sliced meats, puddings, pastries, and sandwiches. |
Vibrio 1 – 4 days |
Watery diarrhea, nausea. stomach cramps, vomiting, fever, chills | Raw or undercooked shellfish, particularly oysters |
Some foods are more associated with foodborne illnesses and food poisoning than others. They can carry harmful germs that can make you very sick if the food is contaminated.
Thoroughly cooking chicken, poultry products, and meat destroys germs.
Raw and undercooked meat and poultry can make you sick. Most raw poultry contains Campylobacter. It also may contain Salmonella, Clostridium perfringens, and other bacteria. Raw meat may contain Salmonella, E. coli, Yersinia, and other bacteria.
The safest fruits and vegetables are cooked; the next safest are washed. Avoid unwashed fresh produce.
Eating fresh produce provides important health benefits, but sometimes raw fruits and vegetables may cause food poisoning from harmful germs such as Salmonella, E. coli, and Listeria. Fresh fruits and vegetables can be contaminated anywhere along the journey from farm to table, including by cross-contamination in the kitchen.
To prevent listeriosis, don’t consume raw milk and soft cheeses and other dairy products made from unpasteurized milk.
You can get very sick from raw milk and from dairy products made with raw milk, including soft cheeses such as queso fresco, blue-veined, feta, brie and camembert, as well as ice cream and yogurt. They can carry harmful germs, including Campylobacter,
Cryptosporidium, E. coli, Listeria, and Salmonella.
Cook eggs until the yolks and whites are firm.
Eggs can contain a germ called Salmonella that can make you sick, even if the egg looks clean and uncracked. Use pasteurized eggs and egg products when preparing recipes that call for raw or undercooked eggs. In addition:
Raw or undercooked oysters can contain Vibrio bacteria, which can lead to an infection called vibriosis.
Cook seafood to 145°F, and heat leftover seafood to 165°F. Avoid raw or undercooked fish, shellfish, or food containing raw or undercooked seafood, such as sashimi, some sushi, and ceviche.
Eating raw or lightly cooked sprouts, such as alfalfa, bean, or any other sprout may lead to food poisoning.
The warm, humid conditions needed to grow sprouts are also ideal for germs to grow. Eating raw or lightly cooked sprouts, such as alfalfa, bean, or any other sprout may lead to food poisoning from Salmonella, E. coli, or Listeria. Thoroughly cooking sprouts kills the harmful germs and reduces the chance of food poisoning.
You should never taste raw dough or batter.
Flour is typically a raw agricultural product that hasn’t been treated to kill germs. Harmful germs can contaminate grain while it’s still in the field or at other steps as flour is produced. Bacteria are killed when food made with flour is cooked. That’s why you should never taste raw dough or batter.
