• #1 Listeriosis – Wikipedia

  https://en.wikipedia.org/wiki/Listeriosis

  The main means of prevention is through the promotion of safe handling, cooking, and consumption of food. This includes washing raw vegetables and cooking raw food thoroughly, as well as reheating leftover or ready-to-eat foods like hot dogs until steaming hot. […] Another aspect of prevention is advising high-risk groups such as pregnant women and immunocompromised patients to avoid unpasteurized pts and foods such as soft cheeses like feta, Brie, Camembert cheese, and bleu. Cream cheeses, yogurt, and cottage cheese are considered safe. In the United Kingdom, advice along these lines from the Chief Medical Officer posted in maternity clinics led to a sharp decline in cases of listeriosis in pregnancy in the late 1980s. […] Another method of controlling the presence of the Listeriosis-causing pathogen L. monocytogenes is by spraying foods with the additive product Listex P100 bacteriophage, which infects and kills the cells through what is called the lytic cycle, eliminating that pathogen from the food. Many food production companies spray their products with this bacteriophage before packaging because it does not alter the flavor, color, or quality of the food. Studies have shown that Listex P100 is successful at eliminating L. monocytogenes from raw salmon fillet tissue, catfish fillets, fruit, surface-ripened soft cheese, hot dogs, cooked and slices of turkey breast meat, smoked salmon, mixed seafood, chocolate milk, mozzarella cheese brine, iceberg lettuce, cabbage, and sausage. In addition, no genetic resistance to P100 phage has been reported from present studies on Listeria isolates.

  Administration of parenteral procaine penicillin G or oxytetracycline […] Recovery from listeriosis depends on early, aggressive antimicrobial treatment. The survival rate with treatment is lower in cattle exhibiting recumbency, excitement, and a weak or absent menace reflex. L monocytogenes is susceptible in vitro to penicillin (the drug of choice), ceftiofur, oxytetracycline, erythromycin, and trimethoprim/sulfonamide. High doses are required because of the difficulty in achieving minimum bactericidal concentrations in the brain. […] Results with vaccines have been equivocal, which together with the sporadic nature of the disease, lead to questions about the cost versus benefit of vaccination. In an outbreak, affected animals should be segregated. If silage is being fed, use of the particular silage should be discontinued on a trial basis. Spoiled silage should be avoided. Corn ensiled before being too mature and grass silage containing additives are likely to have a more acidic pH, which discourages multiplication of L monocytogenes.

  Listeria monocytogenes (Lm) is a foodborne pathogen of international public health concern. […] Control of Lm can be difficult, since it is widely distributed and persists along the entire food supply chain, can re-contaminate RTE foods, and can grow to high levels at typical refrigeration temperatures. […] Despite these challenges, the U.S. has successfully reduced the incidence of listeriosis by over 42% in the past decade primarily as a result of a regulatory risk management strategy that motivated industry adoption of more effective Lm processing controls and implementation of enhanced sanitation programs to prevent Lm contamination of meat and poultry products. […] This chapter explores the systematic conduct and use of microbiological risk assessments to effectively guide federal policies and programs, creation of a regulatory environment that supported industry efforts to prevent Lm contamination of RTE meat and poultry products, and the resulting shared public-private success in reducing the risk of listeriosis in the U.S.
