    Ecoli group Ecoli group It does not represent one or a genus of bacteria but refers to a group of bacteria associated with fecal contamination with certain characteristicsEcoli groups are euphems directly or indirectly from humans and warm-blooded animalsIn general food, ecoli group exceeds the standard indicates that food affected by the feces of warm blood animals where the typical Ecoli for feces recently contaminated other bacteria may be old pollution of fecesPeople eat ecoli bacteria over the standard of food may cause: intestinal infectious diseases, food poisoning and so onMold mold is a silky fungus commonly known as "moldy fungi" they tend to form branched mycelium but do not produce large sub-entities like mushroomsIn a humid and warm place many items grow some light, floc or spider web-like colonies that are visible to the naked eye, which is moldMold everywhere in our lives It prefers warm and humid environment simply to a warm and humid environment when there is a suitable environment will be a large number of reproduction must take measures to prevent the reproduction of mold or cut off its transmission path can get rid of mold pollutionMycotoxins are mainly toxic to humans in neuroandal and endocrine disorders, immunosuppression, cancer-causing teratogens, liver and kidney damage, reproductive disorders and so onYeast yeast is a unit of some single-cell ediguent fungi that are not classified for systematic evolutionIs the sub-cystic bacteria, bacteria and other single-cell edifying fungus generally refers to the fermentation of sugar sacs of a variety of single-celled fungi are pathogenic bacteriaAir, human body there is a certain number of yeast as long as in the right environment will quickly reproduce eat yeast-contaminated food easy to cause food poisoning some low immunity of the population may also occur yeast infectionStaphylococcus aureus Staphylococcus aureus is an important pathogen of human beings belonging to the staphylococcus genus genus has a "meat-obsessed bacteria" is a representative of gram-positive bacteria can cause many serious infectionsStaphylococcus aureus is found everywhere in nature in air, water, dust and excreta by humans and animalsAs a result, there are many opportunities for food to be contaminatedThe U.SCenters for Disease Control reported that Staphylococcus aureus caused the second most infection after EcoliStaphylococcus aureus is the most common pathogen in human pus infection can cause localized pus infection can also cause pneumonia, pseudo-membrane enteritis, permitititititand and even septicaemia, sepsis and other systemic infectionsSalmonella salmonella is a common foodborne pathogenic bacteriaSalmonella is a disease-causing human that only causes disease in animals and has disease sourm in both humans and animalsSalmonella is the general term for different forms of human, domestic and wild animals caused by various types of salmonellaContaminated food from people infected with salmonella or those infected with bacteria can cause food poisoningAccording to statistics in the world's various types of bacterial food poisoning caused by salmonella often ranked firstSalmonella mainly contaminates meat food fish, poultry, milk, egg food can also be contaminated with this bacteriaSalmonella food poisoning can occur throughout the year when uncooked disease, dead livestock meat or livestock meat contaminated in other areas after slaughter is the most important cause of salmonella food poisoningThe symptoms of food poisoning caused by salmonella are nausea, vomiting, abdominal pain, headache, chills and diarrhea, which are accompanied by fatigue, muscle aches, blurred vision, moderate fever, restlessness and drowsinessShigella Shigella Shiga's bacteria, commonly known as dysentery Dysentery Heshiga's bacteria are the pathogens that cause typical bacterial dysentery that can cause disease in a small number of individuals in sensitive populations Shigella food poisoning refers to bacterial food poisoning caused by Shigella Shigella, which causes food poisoning, is mainly Shiga bacteria in Songne Mainly occurred in summer and autumn caused poisoning of food is mainly hot meat products Shigella invades the intestinal mucosa tissue and releases endotoxins to cause symptoms The incubation period is general Symptoms are severe abdominal pain, diarrhea water samples can bring blood and mucus, fever, acute and heavy Severe lysic spasms and shock Hemolytic streptococcal hemolytic streptococcus is sensitive to heat and chemical antidotes often cause infections in the tonsils, pharynx, middle ear, etc It is also a pathogen of nephritis, hemorrhoid fever and scarlet fever Generally speaking, hemolytic streptococcus often pollutes food through the following channels: food processing or sales staff oral, nasal cavity, hands, face septic inflammation caused by food pollution, food before processing has been bacteria, cows suffering from purulent mastitis or livestock local pus when some parts of the milk and carcasses pollution, cooked food products due to poor packaging and food contamination Hemolytic streptococcus can often cause skin, subcutaneous tissue purulent inflammation, respiratory infections, epidemic pharyngitis outbreak epidemic and neonatal sepsis, bacterial endocarditis, scarlet fever and rheumatoid fever, nephritis and other perverted reactions Listeria list edified nucleoccus, Listeria is a combination of anaerobic bacteria for listedomystine pathogens Listeria is a Gramemuna-positive genus thick-walled bacteria named after Joseph Lister It is mainly food-borne vector son of one of the most deadly foodborne pathogens Listeria is found everywhere in the environment and in most foods Meat, eggs, poultry, seafood, dairy products, vegetables, etc have been confirmed as the source of listeria infection Healthy adult individuals with listeria infection may exhibit mild flu-like symptoms in newborns, pregnant women, immunodeficiency patients with shortness of breath, vomiting, hemorrhagic rash, purulent conjunctivitis, fever, convulsions, coma, natural abortion, meningitis, septicaemia until death E coli E coli is a normal habitat bacteria in the intestines of humans and animals One of the pathogenic substances of E coli is plasma coagulase According to the pathogenicity of different diarrhea-induced e coli bacteria are divided into enterotoxin-producing e coli, intestinal invasive e coli, intestinal pathogenic E coli, entero-aggrandizing adhesion E coli and enterohemorrhagic e coli Common poisoned foods are all kinds of cooked meat products, cold meals, beef, raw milk next to eggs and egg products, cheese and vegetables, fruits, beverages and other food The main cause of poisoning is that contaminated food is not thoroughly heated before it is eaten Poisoning occurs mostly in months and months The symptoms of poisoning caused by different diarrhea-causing e coli bacteria vary (1) The production of enterotoxin colibacteria can cause water-like diarrhea, abdominal pain, nausea, low fever (2) Intestinal aggressive eoscoccal exiosis can cause fever, severe abdominal pain, watery diarrhea, small amounts of mucus and blood in feces (3) Intestinal pathogenic eoscoccal exiosis can cause fever, discomfort, vomiting, diarrhea, feces with a large amount of mucus but bloodless patients infected by respiratory symptoms are usually more serious symptoms (4) Intestinal agglomeration adhesion eichbacteria can cause moderate diarrhea in adults, infants and young children above the week persistent diarrhea (5) Intestinal hemorrhagic e coli bacteria can cause sudden abdominal cramps, diarrhea Some patients from water-like to blood diarrhea sometimes up to multiple low fever or fever many patients have respiratory symptoms at the same time It can develop into polyorgan damage such as hemolytic uremic syndrome and thrombosis reduced cyanosis The mortality rate for the elderly and children is high Parahetic Vibrio subhemolytic Vibrio is a Gram-negative bacillus with arc-like, rod-like, silk-like and other shapes without spores Eating food containing the bacteria can cause food poisoning, also known as salt-eating bacteria food poisoning Clinically, acute onset, abdominal pain, vomiting, diarrhea and water-like stool are the main symptoms Parahemolytic Vibrio is a marine bacteria mainly derived from fish, shrimp, crab, shellfish and seaweed and other seafood The bacteria is sensitive to acid in ordinary vinegar in a minute to kill the less resistant to heat Botox Botox Botox is one of the most toxic bacteria that grows in oxygen-deprived environments and has a strong survivability in canned foods and sealed pickled foods Botox is a deadly bacteria that secretes botulinum toxins during reproduction The most toxic toxin known to inhibit choline can cause nerve endings to release acetylcholine leading to muscle relaxation paralysis Botox can often be detected in the widely distributed soil of nature, but also in animal waste The gastrointestinal tract of the human body is a good oxygen-deprived environment suitable for Botox to live in Botox belongs to the strict anaerobic bacteria in the gastrointestinal tract can break down glucose, maltose and fructose acid production gas, but also digest and break down the meat residue to make it black and bad smell In anaerobic environment, this bacteria can secrete strong botulinum toxin can cause special neurotoxic symptoms disability rate, disease fatality rate is very high Foods that eat Botox can cause food poisoning such as low-acid canned foods containing tin cans of glass or sausages and ham Humans infected with Botox will appear visual blur, breathing difficulties, muscle weakness and other symptoms such as serious illness may lead to death Vibrio cholerae Vibrio cholerae is a human cholera pathogen cholera endemic is one of the ancient and widespread infectious diseases There have been many pandemics in the world, mainly manifested in the high mortality rate of severe vomiting diarrhea and dehydration It belongs to the international quarantine infectious disease Humans are naturally the only susceptible to Vibrio cholerae transmission mainly through contaminated water sources or undercooked food such as seafood, vegetables through the mouth Poor sanitation in residential congestion, especially public water sources, is an important factor in the outbreak Control in production is mainly a rigorous audit of the source of raw materials and sterilization treatment in the production process Morphine Pycobacteria is a parasitic and pathogenic bacteria in humans and animals Widely distributed in nature such as soil, water, garbage, corrupt organic matter and the intestines of humans or animals Can cause a variety of infections Poisoning food mainly to animal food mainly for the soy products and cold vegetables season in summer, autumn poisoning causes for contaminated food before consumption did not thoroughly heat the deformation of bacillus food poisoning is one of the common food poisoning in China After eating , the upper abdominal knife-like pain and acute diarrhea are accompanied by nausea , vomiting , headache , fever The short course of illness generally can be restored to the day with very few deaths Air enteroconctific bacteria Air enteroconctifyamy body mildly bent like a teasing point in the dark field of view to observe like flying flies There is a membrane that does not form bud cells The optimum temperature is Cannot grow in a normal atmosphere or in an oxygen-free environment Empty courtry is a normal resident bacteria in a variety of animals such as cattle, sheep, dogs and birds There are a lot of bacteria in their reproductive tract or intestines that can contaminate food and drinking through childbirth or excreta The incidence of children with general susceptibility is highest in summer and autumn Flies also play an important media role It can also be contracted through contact Infected mothers can transmit to the fetus during childbirth Empty enterobacteria have endotoxins that can attack the small intestine and the ocosa mucosa caused by acute enteritis can also cause outbreaks of diarrhea epidemic or collective food poisoning The bacteria can sometimes cause sepsis and other organ infections such as meningitis, arthritis, nephritis, etc through enterocardy membrane into the bloodstream Infection with the bacteria in pregnant women can lead to premature miscarriage and can infect newborns A genus of bacillus spores The rod-like endof of the bacterial cell is positive for short or long chain Gram Wax-like bacillus is associated with a small number of food poisonings - including some severe nausea, vomiting, and abdominal pain Presumably, bacillus food poisoning is caused by incorrect cooking methods to cause bacterial spores to remain on food, worse, food is improperly frozen and spour germinates The result of bacterial reproduction is that enterotoxins can produce vomiting, diarrhea and other adverse symptoms after eating foods containing toxins Flat acid bacteria flat acid bacteria is causing canned food acid deterioration and not fat listening to that acid-producing non-gas-producing microorganisms in the canning industry called flat acid bacteria It is acoysal anaerobic bacillus It is widely distributed in soil dust and all kinds of spoiled food Accidental eating of flat acid bacteria caused by the deterioration of canned cans can cause food poisoning diarrhea, vomiting and other symptoms Yerson bacteria Yersinia belongs to the E coli branch including plague Yebacteria, small enterocol colitis jesterise and pseudo-tuberculosis Jesillisa and other more than a dozen species this is a class of Gram-negative small bacteria Its plague yeritis, small intestine colitis jesterise and pseudo-tuberculosis Jexibacteria in human seismology has been clear lying in which the plague Jexibacteria has 、、、 and important toxic factors strong a small number of bacteria can cause disease This genus bacteria usually cause infection in rodents, livestock, and birds, and humans are infected by touching infected animals, eating contaminated food, or arthropod bites Hansaki E coli is a pathogenic bacteria in dairy products Hansaki E coli can cause severe neonatal meningitis, small enterocolitis and mycosis mortality rate as high as above Microbiologists do not yet know the source of contamination of E Coliforms, but many case reports indicate that infant formula is the main source of infection currently found.
