Can food poisoning only develop immediately after contaminated food had been eaten?

  • No. Some food poisoning may require hours before enough bacteria are present to cause symptoms. In fact, that is typical. Salmonella, one of the most common food poisonings generally does not manifest until 24 hours after ingestion.

  • Answer: No. Some food poisoning may require hours before enough bacteria are present to cause symptoms. In fact, that is typical. Salmonella, one of the most common food poisonings generally does not manifest until 24 hours after ingestion.
  • Answer: Yes it can. If it is particularly bad then it tends to happen earlier.
  • Answer: Yes, there is often a period in which there are enoughmicroorganisms to make you sick but not enough to be detectable bythe look, taste, or smell of the food. But eventually those thingswill be affected.
    One very early warning that usually occurs well before thereare enough microorganisms to make you sick is the surface of thefood develops a "slimy" feel. It is still usually safe to eat suchfood when this just begins, especially if you cook it as themicroorganisms are still only on the surface of the food. But becautious! Note: this does not apply to ground meats and choppedfoods, if they get "slimy" throw them out immediately!
  • Answer: Packaged food can become contaminated through poor production practices, packaging failure or mishandling anywhere along the production-distribution-consumer route.
  • Answer: The only sure way is to eat it and see if you get sick.
    Only in rare cases will contamination cause obvious "spoiling" of food, But the old standby of checking for gas production (most canned food is under a mild vacuum) is still useful.
    There are lab tests (culture the food) but they take longer to do than is useful (but is used to test large batches of food by industry).
  • Answer: it causes food poisiong because the microbes are not good for the body. when it is chewed and goes into the stomach and spreads into tiny particles and burns vigurously. lol i dont know i just made all of that up in my head.
  • Answer: This all depends on how fast your body processes the food, generally the average is around, about 8 hours maybe a couple less.It can take anywhere from 6 hours to 48 hours after being exposed to contaminated food. More information There are many causes of foodborne illness. Ingested toxins can hit very quickly within a couple hours. Ingested microbes can take a while to build up the effect - which can mean days or even weeks. See Related Links.
    Symptoms can occur within an hour; or can take as long as 36 hours to appear.
  • Answer: To prevent food poisioning, premises are often designed in a linear flow:Back door: products arrived > Sink: Product cleaned > Fridge: Product stored at correct temperature > Preparation area > Cooking Area > Service AreaThe main aim is to prevent cross-contamination amongst products. Also fridges are designed in a way whereby raw meat is stored below ready to eat products such as salad leaves. Any product which is ready to eat is a HIGH-RISK product, and needs to careuflly handled with a food business to prevent contamination.To prevent food spoilage, a premises should be designed to encourage stock rotation, perhaps through adequate storage space.
  • Answer: The knowledge of food poisoning can absolutely stop food poisoning by several factors:
    Food handlers do so in a way to ensure the cleanest of conditions and eliminate the possibilities of cross contamination.
    Food preparers do so in a way as to prevent cross contamination.
    Food purchasers do so in a way as to ensure their suppliers follow strict, pre-established guidelines ensuring the best possible products.
    Consumers use "fresh food wash" type cleaners to ensure the foods are salmonella, e.coli, bacteria, insecticide and food borne pathogen free before preparing and cooking the foods.
    The CitroBio Fresh Food Wash has been shown in independent testing to stop food poisoning, salmonella, e.coli and other food borne pathogens.

  • Answer: There are a number of ways in which food can make you sick.Chemicals, heavy metals, foreign objects, food-infesting insects,parasites, fungi, viruses and bacteria are all possible causes.
    The greatest, and by far most common risk of becoming ill or dyingfrom food is from contamination with harmful microorganisms,commonly known as germs. The likelihood of becoming seriously illby microorganisms is far greater than that of pesticide risks,environmental contaminants, nutritional imbalances, food additivesand natural toxicants.
    Microorganisms include bacteria, viruses, molds, and parasites. Ofthe many types of microorganisms, bacteria and viruses are themajor source of foodborne illness cases in most of the world.
    Microbial food poisonings or foodborne illnesses mainly fall intoone of two categories. The first is foodinfection, where the microorganism itself growsinside your body and is the source of your symptoms. An example ofhtis is Salmonella. The second type is foodintoxication, where a chemical or natural toxin(often produced as a by-product of bacteria present in the food -known as an exotoxin) causes your symptoms or illness. A bacteriaknown to cause intoxication is Staphylocuccos aureus.
    Most bacterial food poisonings are actually food infections. Thesymptoms of food infection and food intoxication are similar. Bothcan produce food poisoning related symptoms, such as headaches,vomiting, abdominal pain, cramps, diarrhea, dehydration, and so itis not always clear which you are experiencing. Some dangerousbacteria such as Clostridium botulinum can cause death ifa person is not treated immediately.
