Why do bacteria in food make you sick?
The bacteria multiply in the food and by-product of this multiplication is toxin, the poison that causes illness. The toxin producing bacteria can multiply in the food or in the body and not all toxins are destroyed by cooking. The most common symptom od this intoxication is vomiting.
What is bacterial intoxication?
Bacterial Intoxication. • Food poisoning intoxication can occur when the food eaten is contaminated with toxins (poison) or toxin producing bacteria. • When these bacteria multiply in the food or in the body, a toxin is produced.

Intoxication: occurs from eating a food that contains a toxin produced by bacteria. An example of food intoxication is Clostridium botulinum poisoning. Intoxification: occurs when live bacterial cells are ingested which then produce toxins in the body. An example of food intoxification is Clostridium perfringens.
What causes food intoxication?
Food poisoning is an illness caused by eating contaminated food. It's not usually serious and most people get better within a few days without treatment. In most cases of food poisoning, the food is contaminated by bacteria, such as salmonella or Escherichia coli (E. coli), or a virus, such as the norovirus.

Foodborne intoxication, more commonly known as food poisoning, is caused by eating food that contains toxins that are released by pathogens; the pathogens themselves do not cause illness.
What is the difference between food poisoning and intoxication?
The major difference between food intoxication and food infections lies in the origin of the illness-causing toxins. While food intoxication/poisoning is caused by toxins released by microorganisms after they are ingested, food infections are caused by the presence of toxins in food before consumption.

More than 90 percent of the cases of food poisoning each year are caused by Staphylococcus aureus, Salmonella, Clostridium perfringens, Campylobacter, Listeria monocytogenes, Vibrio parahaemolyticus, Bacillus cereus, and Entero-pathogenic Escherichia coli. These bacteria are commonly found on many raw foods.
How can food poisoning bacteria be prevented?
Therefore, illness can be prevented by (1) controlling the initial number of bacteria present, (2) preventing the small number from growing, (3) destroying the bacteria by proper cooking and (4) avoiding re-contamination.
How to prevent food poisoning?
The first step in preventing food poisoning is to assume that all foods may cause food-borne illness. Follow these steps to prevent food poisoning: 1 Wash hands, food preparation surfaces and utensils thoroughly before and after handling raw foods to prevent recontamination of cooked foods. 2 Keep refrigerated foods below 40 degrees F. 3 Serve hot foods immediately or keep them heated above 140 degrees F. 4 Divide large volumes of food into small portions for rapid cooling in the refrigerator. Hot, bulky foods in the refrigerator can raise the temperature of foods already cooled. 5 Remember the danger zone is between 40 degrees F and 140 degrees F. 6 Follow approved home-canning procedures. These can be obtained from the Extension Service or from USDA bulletins. 7 Heat canned foods thoroughly before tasting. 8 When in doubt, throw it out

Wash hands, food preparation surfaces and utensils thoroughly before and after handling raw foods to prevent recontamination of cooked foods.
What foods can cause salmonella?
Salmonella. The gastrointestinal tracts of animals and man are common sources of Salmonella. High protein foods such as meat, poultry, fish and eggs are most commonly associated with Salmonella. However, any food that becomes contaminated and is then held at improper temperatures can cause salmonellosis.
How does S. aureus cause illness?
Man’s respiratory passages, skin and superficial wounds are common sources of S. aureus. When S. aureus is allowed to grow in foods, it can produce a toxin that causes illness. Although cooking destroys the bacteria, the toxin produced is heat stable and may not be destroyed. Staphylococcal food poisoning occurs most often in foods that require hand preparation, such as potato salad, ham salad and sandwich spreads. Sometimes these types of foods are left at room temperature for long periods of time, allowing the bacteria to grow and produce toxin. Good personal hygiene while handling foods will help keep S. aureus out of foods, and refrigeration of raw and cooked foods will prevent the growth of these bacteria if any are present.
What temperature should bacteria grow?
The temperature range in which most bacteria grow is between 40 degrees F (5 degrees C) and 140 degrees F (60 degrees C). Raw and cooked foods should not be kept in this danger zone any longer than absolutely necessary. Undercooking or improper processing of home-canned foods can cause very serious food poisoning.
What is foodborne intoxication?
Foodborne intoxication is more commonly referred to as food poisoning. It's caused when foods that contain toxins from pathogens are eaten. Botulism would be an example of food borne intoxication. This type of illness is caused by botulinum toxins, not the bacteria that produce it as is the case with any foodborne intoxication.
What are the most common foods that cause food poisoning?
Meat, poultry, dairy, eggs, and fish can all contain pathogens that risk food illness. If any of these foods are not cooked all-the-way through, or handled improperly, they can spread infection to public health and cause food poisoning to occur.
What are the symptoms of foodborne illness?

Where is Clostridium botulinum found?
Clostridium botulinum- Found throughout nature in soil, water and plants. It's also prevalent in the intestines of fish and animals. This bacteria produces a toxin which causes foodborne intoxication when consumed. It affects the nervous system causing symptoms such as double vision or difficulty swallowing or breathing to occur in in 18 to 36 hours. Sometimes symptoms won't appear for a few days after eating the toxin and it can be fatal if not treated quickly.

How to protect against food poisoning from bacterial toxins?
This means the only way to protect against food poisoning from bacterial toxins is to control the conditions in which high-risk foods like meat, poultry, seafood and dairy are handled. Like all bacteria, toxin-producing bacteria need certain things to live, such as nutrients and moisture.
What is the difference between exotoxins and endotoxins?
Exotoxins are generated and actively secreted, while endotoxins remain part of the bacteria. Usually, an endotoxin is part of the bacterial outer membrane, and it is not released until the bacterium is killed by the immune system, which can cause severe inflammation and can even lead to sepsis.
What are the symptoms of food poisoning?
Bacterial toxins damage tissues and disable the immune system, causing acute symptoms of food poisoning (e.g. vomiting, nausea, diarrhea, lightheadedness). When bacterial toxins reach organs, such as the kidney or the liver, the central nervous system or the peripheral nervous system, they can cause serious damage or even death.
How do exotoxins affect the host?
Exotoxins are highly potent and can cause major damage to the host by destroying cells or disrupting normal cellular metabolism. Exotoxins may be secreted, or, like endotoxins, may be released when the bacterium cell is broken down in the body.
