Salmonella what is the infectious agent

Do not consume raw or unpasteurized milk or other dairy products. Do not consume raw or undercooked eggs. Discard cracked eggs. Keep eggs refrigerated. Thoroughly wash produce before eating it. Avoid cross-contamination of foods. Keep uncooked meats separate from produce, cooked foods, and ready-to-eat foods. Thoroughly wash all utensils, including cutting boards, knives, and counters, after handling uncooked foods. Thoroughly wash hands before handling foods and between handling different food items.

Thoroughly wash hands after contact with feces. Thoroughly wash hands after handling any reptiles or birds, since reptiles and birds are particularly likely to carry salmonella. When should I call my healthcare provider? Key points about salmonella infections Salmonella infections are diarrheal infections caused by the bacteria salmonella. Symptoms of a salmonella infection may include diarrhea, fever, abdominal cramps 12 to 72 hours after infection chills, headache, nausea, or vomiting.

Treatment may not be necessary unless dehydration happens or the infection spreads to the blood stream. Prevention includes cooking foods properly, avoiding raw milk and eggs, washing food, utensils, hands, and kitchen surfaces properly. Next steps Tips to help you get the most from a visit to your healthcare provider: Know the reason for your visit and what you want to happen. Before your visit, write down questions you want answered.

Bring someone with you to help you ask questions and remember what your provider tells you. At the visit, write down the name of a new diagnosis, and any new medicines, treatments, or tests. Also write down any new instructions your provider gives you. Know why a new medicine or treatment is prescribed, and how it will help you. Also know what the side effects are. Stools should be collected from cases, and attempts made to identify a common source by obtaining food histories and potentially relevant environmental exposures.

Any implicated foods should be retained for analysis at the Microbiological Diagnostic Laboratory at the Peter Doherty Institute. Staff of the department conduct environmental investigations, usually in conjunction with local councils. International outbreaks are increasingly being recognised, primarily due to the increased dissemination of food and agricultural products worldwide.

Infectious agent of salmonellosis Approximately 2, known serotypes exist of Salmonella spp. Identification of salmonellosis Clinical features Salmonellosis commonly presents as an acute gastroenteritis with fever, vomiting, nausea, abdominal pain, headache and diarrhoea.

Diagnosis Infection is diagnosed by isolation of Salmonella spp. Incubation period of Salmonella The incubation period is usually 6—72 hours, with an average of 12—36 hours. Public health significance and occurrence of salmonellosis Salmonella infection occurs worldwide, and only a small proportion of cases are detected and reported.

Reservoir of Salmonella Domestic and wild animals, including poultry and reptiles, act as reservoirs. Mode of transmission of Salmonella Transmission is usually person-to-person or animal-to-person via the faecal—oral route, through ingestion of the organisms via contaminated or improperly cooked foods.

Foodborne transmission occurs particularly with: raw and undercooked eggs and egg products raw milk and raw milk products poultry and poultry products raw red meats unwashed salads, fruits and vegetables, grains, seeds and nuts some shellfish and filter feeders, such as oysters. Period of communicability of salmonellosis Salmonellosis is communicable through the course of infection, usually several days to several weeks.

Susceptibility and resistance to salmonellosis Susceptibility may be increased by some medical conditions and treatments, including immunosuppressant therapy, prior or concurrent broad-spectrum antibiotic therapy, gastrointestinal surgery, antacid use, achlorhydria and malnutrition. Severity of the disease varies with: the serotype the numbers of organisms ingested the vehicle of transmission host factors.

Control measures for salmonellosis Preventive measures Thoroughly cook all food derived from animals sources, particularly poultry, pork, eggs and egg products, and other meat dishes. Inadequate temperature control, and incorrect storage of food during and after the cooking process facilitate bacterial multiplication and are important risk factors: Avoid recontamination from raw food within the kitchen or refrigerator, after cooking is completed.

Emphasise the importance of refrigerating food and maintaining a sanitary kitchen. Avoid consuming raw or incompletely cooked eggs, or using dirty or cracked eggs. Pasteurise all milk and egg products. Educate food handlers on the importance of handwashing, and separating raw and cooked foods. Control of case Treatment is supportive, and antibiotics are not indicated in uncomplicated gastroenteritis because they may prolong the carrier state and promote antibiotic resistance.

Instruct asymptomatic individuals in strict personal hygiene, especially proper handwashing. Control of contacts Consider the diagnosis in symptomatic contacts.

Cooking for Groups Consumer information about preparing and serving food for large groups.

Information to help volunteers prepare and serve food safely for large groups such as family reunions, church dinners, and community gatherings.

As a food manager or worker you have a responsibility to protect yourself and your guests from foodborne illness. Learn what you can do to prepare, serve and store food safely. Protect others if you are experiencing diarrhea!

Anyone with a diarrheal illness should avoid swimming in public pools or lakes, sharing baths with others, and preparing food for others. Young children children in diapers that are experiencing diarrhea should not be allowed to go swimming or attend daycare.
