Bacillus Cereus are micro-organisms found in a variety of food items. They occur naturally and are a cause of food poisoning. The two major types of food poisoning that are caused by these bacteria are diarrhea and emetic. Toxins produced by these bacteria cause food poisoning. Of thousands of cases of microbial poisoning reported each year, this bacterium accounts for only 5% of the total number. Generally, the disease does not last for long and the patient recovers in a day or two. The food items which cause this type of Food poisoning caused due to Bacillus Cereus generally stems from food items like cooked rice or food that is stored at lower or higher temperatures after cooking.
More about bacteria
To know more about this disease, you should have a proper knowledge about the bacteria that causes it and its nature. Bacillus Cereus is a type of bacteria that is known for producing toxins and spores, both of which are extremely harmful for the human body. The growth of the bacterium is the best when the temperature is between 30-37 degrees. Some forms may even grow at 55 degrees and some at as low as 4 degrees. There is a particular pH-range for the growth of all the different types of micro-organisms and for Bacillus Cereus it is 4.3 to 9.3.
These particular bacteria grow the best in the presence of oxygen, although they can also grow without oxygen at all. The bacteria get killed but the spores can sometimes have a resistance against heat. If the bacteria are present in high fat or oily food, the heat resistance is then also increased. Often times when the foods have low water activity the resistance is then increased. The food poisoning by this microbe is of two types. The first which is a diarrhea illness that is caused in the presence of unstable acid called entero toxin.The other an emetic illness is however caused by another type of toxin that can easily be alive even in the high temperatures and also with extreme pH levels.
What is Diarrhea poisoning?
It is important to know the symptoms of the disease so that you may take the proper actions to fight against these harmful causes. When the person has diarrhea poisoning, the body will undergo several different changes. For example cramps, nausea, abdominal pain and diarrhea are some of the most common symptoms of this type of food poisoning. The bacteria multiply at a fast rate causing problems to the person who has consumed the food product. This bacteria also emits toxins as they multiply in the affected persons intestine.
An explanation of Emetic poisoning:
Some common symptoms of emetic poisoning are nausea and vomiting. Other people may also witness diarrhea after these two initial symptoms. In case of this food poisoning the symptoms can start occurring one to six hours after the consumption of the food item. If you or anyone in your family has these symptoms, make sure you visit the doctor or a lab and give a fecal specimen to confirm food poisoning of this type. Remember that to different people sometimes symptoms vary so make sure to learn about these different poisons.
