Food-borne Diseases in Children

Food-borne diseases are defined as diseases, usually either infectious or toxic in nature, caused by agents that enter the body through the ingestion of food. Every person is at risk of food-borne diseases.

Children have unique exposure pathways. They can be exposed in utero to toxic environmental agents that cross the placenta. Such exposures can be biological (viral, bacterial, parasitic) or chemical (pesticides, toxins). They can also be exposed to pollutants that pass into their mother’s milk. Neither of these routes of exposure occurs in adults or older children

Children also have pathways of exposure that differ from those of adults due to their size and developmental stage. For example, young children engage in normal exploratory behaviours including hand-to-mouth and object-to-mouth behaviours, and non-nutritive ingestion which may dramatically increase exposure over that in adults.

The amount of food that children consume per kilogram of body weight is higher than that of the adult because children not only need to maintain homeostasis, as adults do, but are growing. The average infant consumes 5 oz. of formula per kilogram of body weight (for the average male adult, this is equivalent to drinking 30 12 oz. cans of liquid a day.) If the food or liquid contains a contaminant, children may receive more of it relative to their size than adults.

In addition, children consume different types of food. The diet of many newborn babies is exclusively breast milk. The diet of children usually contains more milk products and certain fruits and vegetables than the typical adult diet.

Symptoms of food born diseases

The symptoms of food-borne disease vary depending on the agent causing illness.

Symptoms may include diarrhoea, vomiting, nausea, abdominal pain, and fever.

Symptoms can take anywhere between a few hours, a few days, or even several weeks to develop. Symptoms usually last for a few days, but can last longer. Dehydration can be a complication in young children and t he elderly.

 How the food-borne disease spread

There are a number of opportunities for food to become contaminated as it is produced, processed, prepared and handled.

Usually people are infected after eating inadequately cooked food or by cross contamination.

Agents that cause food-borne disease can also be spread directly from animals to humans or from person-to-person.

Inadequate cooking Food-borne disease can be spread from eating poorly cooked foods. Raw or undercooked eggs, meat and poultry are particularly high risk foods.

Cross contamination

Cross contamination occurs when germs are spread to food from other food, surfaces, hands or equipment.

Who is at risk of infection?

Anyone can be infected but some people are more susceptible. These include infants, elderly, people with suppressed immune systems and pregnant women.

How is it diagnosed?

Food-borne disease is usually diagnosed based on a person’s symptoms, although laboratory confirmation from testing faecal samples is important during outbreaks.

What treatment is available?

Most people usually recover with rest and extra fluids. Antibiotics are not usually required but may be recommended by doctors in some cases.

How is it prevented?

Hand washing:

Hand washing is a very effective way of preventing cross contamination and person- to- person spread of food-borne disease agents.

Hands should be washed with soap and running water for between 10 and 15 seconds:

  • before preparing food;
  • before handling raw and ready-to-eat food;
  • before eating;
  • after going to the toilet or changing nappies;
  • after handling pets;
  • and after working in the garden.

Safe food handling and storage:

Adopting safe food handling and storage techniques can effectively prevent the spread of food-borne illness. Remember to follow these food safety rules:

  • Keep food preparation areas and utensils clean.
  • Use separate cutting boards and utensils when preparing raw foods and ready-to-eat foods.
  • Thoroughly cook all raw food.
  • Avoid using cracked or dirty eggs.
  • In the fridge, keep raw foods on a lower shelf than ready-to-eat foods to avoid cross-contamination.
  • Keep food below 5ºC or above 60ºC.
  • Reheat food until it is steaming (internal temperature at least 75ºC ).
  • Wash raw fruit and vegetables before eating them.
  • Only defrost food in a fridge or by using a microwave.
  • Dry dishes with a different dish cloth to that used for wiping hands or kitchen surfaces and wash dish cloths regularly.

  1. Nice blog, and even nice article. They are right when they say you learn something new every day. I even went through and read a few other blog posts as well. What inspired you to write this? And where did you learn it all? This will be helpful to come back to later,I have a child myself.

    1. Thanks dear for your comment.

       It gives me great joy when mothers like you find my articles very helpful, I am very grateful and I would also love if you can help us share it, in other to help us get more feedback which will enable us do more.

      Thanks once again

  2. I have 3 very active children who eat in school. I always wonder about the quality of the food that the caretakers prepare as sometimes they get tummy upset during school days .
    The part where you said : “Usually people are infected after eating inadequately cooked food or by cross contamination.” sounds like the culprit for my kids’ tummy problems.
    Now that I know, do you think I should alert the teachers in their school ?

    1. My opinion is that, you must be very sure about that, because if you are wrong it will be very embarrassing for the school, but if you’re right you will not just be saving your kids but other kids as well who are experiencing similar problems.

  3. Thank you for sharing this post about Food-borne Diseases in Children. As a parent of 7, we are always very careful with what our children eat.

    We limit take-away foods, and when we do eat out, we are always aware of the surroundings. We check for things such as; cleanliness, personal hygiene and cross contamination. It’s absolutely amazing what you will see when you are looking.

    Also, through each of my wife’s pregnancies she has had to be very careful about what she has eaten. If a pregnant mother eats something contaminated, it will not only effect her but can cause major issues with the baby.

    We also teach our children the importance of cleanliness and hygiene when preparing food. For instance; if a butter knife falls on the floor, do not place it back in the butter. Pick it up, wash it, wash your hands and start over.

    What you have shared is very important, because it will also make others well aware of the dangers of food-borne diseases in children and how to avoid them!

    Thanks,
    Jay.

    1. Wow, that’s wonderful. I’m always very happy to see parents who make out time from their busy schedule to educate their kids on in the importance of hygiene and contamination. What we eat really matters, that is why i don’t advice families to always eat outside the home because you wont know how hygienic the food may be and also “families that eats together, stays together”. So Jay i wish other homes can learn from yours. Thanks for the comment

  4. I can relate with this as my 7-year old son had this on several occasions when he started going to school. We let him eat in the cafeteria, but he always got sick. You can already guess what our doctor had to say. Apparently our son is sensitive to this, so we stopped our subscription for the cafeteria food and since we started preparing his lunch ourselves, he hasn’t had any issues at all.

    1. Hi Jurgen thanks for your comments

      Sometimes the way the school prepares the food are not as hygienic as we would want, so it would always affect our children because of the standard that is already set at home. So it is always advisable for parent to monitor the child’s reaction to the school meal before they subscribe another.
