Frequently Asked Questions (FAQs) on food-poisoning | HospitalKhoj



Ques. 1 What is food poisoning?

Ans. Food poisoning is food borne disease. Ingestion of food that contains a toxin, chemical or infectious agent (like a bacterium, virus, parasite, or prion) may cause adverse symptoms in the body. Those symptoms may be related only to the gastrointestinal tract causing vomiting or diarrhea or they may involve other organs such as kidney, brain, or muscle.

Food poisoning is an illness caused by eating foods that have harmful organisms in them. These harmful germs can include bacteria, parasites, viruses. They are mostly found in raw meat, chicken, fish, & eggs, but they can spread to any type of food. They can also grow on food that is left out on counters or outdoors or is stored too long before we eat it. Sometimes food poisoning happens when people don't wash hands before they touch food.

Food poisoning is mild and goes away after a few days. But some types of food poisoning may be more serious, and you may need to see a doctor.

Ques. 2 What are the Symptoms of Food Poisoning?

Ans. Generally, food poisoning causes nausea, vomiting, and diarrhea that may or may not be bloody, sometimes with other symptoms.
a) Vomiting, diarrhea, sweating, excessive salivation, mental confusion, and stomach pain may be symptoms of chemical or toxin food poisoning poisonous mushrooms.
b) Partial loss of speech or blurred vision, muscle weakness, difficulty swallowing, and vomiting may indicate botulism, a severe but very rare type of bacterial food poisoning.
c) After eating tainted food, abdominal cramps, diarrhea, and vomiting, can start as early as one hour. It may take even longer to develop symptoms from parasite infections such as Giardia. Symptoms can last from one day up to a couple of months or longer, depending on type of infection.

Ques. 3 How do harmful germs get into food?

Ans. Germs can get into food when:
a) The food is prepared. When someone who has germs on his or her hands touches the food. For example, if you use the same cutting board for chopping vegetables and preparing raw meat, germs from the raw meat can get on the vegetables.
b) Meat is processed. It is normal to find bacteria in the intestines of healthy animals that we use for food. Sometimes the bacteria get mixed up with the parts of those animals that we eat.
c) The food is watered or washed. If the water used to irrigate or wash fresh fruits and vegetables has germs from animal manure or human sewage in it, those germs can get on the fruits and vegetables.

Ques. 4 How can you protect yourself from salmonella food poisoning?

ii. Diarrhea that lasts longer than 2 days (one day in a child) or is severe
iii. Severe abdominal pain or vomiting
iv. Fever of 102°F or higher (or a rectal temperature of 100.4°F in baby younger than 3 months of age)

Ques. 5 Which are the general guidelines to protect yourself from food poisoning?

Ans. General Guidelines to Prevent Food Poisoning
a) Be aware of proper home-canning procedures.
b) Be careful that you don't let juices or drippings from raw meat, poultry, shellfish, or eggs contaminate other foods.
c) Do not leave eggs, meats, poultry, seafood, or milk for extended periods of time at room temperature. Promptly refrigerate leftovers and food prepared in advance.
d) Avoid unpasteurized milk or foods made from unpasteurized milk.
e) Keep the refrigerator at 40 degrees Farenheit or lower, and the freezer at 0 degrees Farenheit or lower.
f) Wash raw vegetables and fruits thoroughly before eating, especially those that will not be cooked. Avoid eating alfalfa sprouts until their safety can be assured. Methods to decontaminate alfalfa seeds sprouts are being investigated.
g) Drink only pasteurized juice or cider. Commercial juice with an extended shelf life that is sold at the room temperature (juice in cardboard boxes, vacuum sealed juice in glass containers) has been pasteurized, although this is generally not indicated on the label. Juice concentrates are also heated sufficiently to kill the bacteria.
h) If you are ill with diarrhea or vomiting, do not prepare food for others, especially infants, the elderly, and those with weakened immune systems, because they are more vulnerable to infection.
i) Wash hands with soap after handling reptiles, turtles, birds, or after contact with human or pets.
j) Breastfeed your baby if possible. Mother's milk is the safest food for young infants.Breastfeeding may prevent many food-borne illnesses and other health problems.
k) Cook foods until they are steaming hot, especially leftover foods or ready-to-eat foods, such as hot dogs.
l) Make sure that food from animal sources (meat, dairy, eggs) is cooked thoroughly or pasteurized. Use a thermometer to check the temperature of the food.
m) Avoid eating raw or spoiled meats and eggs. Check expiration dates on meats and eggs before purchasing and again before preparing.
n) Carefully select and prepare fish and shellfish to ensure quality and freshness.
o) Although the risk of food-borne disease associated with foods from deli counters is relatively low, pregnant women & people with weakened immune systems may choose to avoid these foods or thoroughly reheat cold cuts before eating.
Food poisoning is common infectious condition that affects millions of people in the United States each year.
Ques. 6 Are food poisoning and stomach flu the same thing?
Ans. Food poisoning and the stomach flu may or may not be the same thing, depending if the causative agent is transmitted by contaminated food, or if the agent is transmitted by non-food mechanisms (such as body secretions). Most health-care professionals equate stomach flu to viral gastroenteritis.
Stomach flu is a non-specific term that describes an illness that usually resolves within 24 hours and is caused commonly by adenovirus, (rotavirus is most commonly found in children).
If numerous cases of "stomach flu" occur in situation where many people have been eating, it certainly may be considered food poisoning. Norwalk virus is responsible for many cases of the food borne illness.

Ques. 7 How long does food poisoning last?

Ans. Most cases of food poisoning last about 1 to 2 days and symptoms resolve on their own. If symptoms persist longer than that, affected person should contact their health-care professional.

Ques. 8 What are the types of food poisoning?

Ans. Most frequently, food poisoning may be due to infection caused by bacteria, viruses, parasites, and infrequently, prions. More than 200 infectious causes exist. Sometimes it is not the bacteria that causes problem, but rather the toxin that bacteria produce in the food before it is eaten. This is case with Staphylococcal food poisoning and with botulism.
Other illnesses may involve chemical toxins that are produced in certain foods that are poorly cooked or stored. For example, scombroid poisoning occurs due to large release of histamine chemical from the fish when it is eaten. It causes facial swelling,itching, and difficulty in breathing and swallowing - just like any allergic reaction. Scombroid poisoning is sometimes confused with a shellfish allergy.

b) Scrombroid poisoning usually is due to poorly cooked or stored fish. The affected person will experience, shortness of breath, and difficulty swallowing within 1 to 2 hours of eating.
c) Ciguatera poisoning is another fish toxin that occurs after eating fish such as grouper, snapper. Symptoms include vomiting and diarrhea, muscle aches, and neurologic complaints including headache, numbness and tingling, hallucinations, & difficulty with balance (ataxia).
Bacterium Causes
i. Bacillus cereus is an infection that occurs after eating poorly cooked or raw rice.
ii. Clostridium perfringens produces a spore that may germinate in cooked meat that has been stored in an environment that was very warm. Within 8 to 12 hours, it may cause profuse diarrhea.

The health-careprofessional may ask questions about symptoms, when they started, and how long they have lasted. A review of systems may help give direction as to what type of infection is present. For example, patient with numbness of their feet and weakness may be asked about whether they have opened any home canned food recently.
Travel history may be helpful to see if patient had been camping near a stream or lake and the potential for drinking contaminated water, or if they have travelled out of the country recently & have eaten different foods than they normally do, such as raw eggs or wild game.
Physical examination begins with taking vital signs of the patient (blood pressure, pulse rate, and temperature). Clinical signs of dehydration include dry, tenting skin, sunken eyes, dry mouth, & lack of sweat in the armpits and groin. In infants, in addition to the above, subtle signs of dehydration may include, poor suckling, and sunken fontanelle.
