Listeria

Listeria monocytogenes is a gram-positive rod-shaped bacterium and facultative anaerobic that can grow under either anaerobic or aerobic conditions but do not form endospores. Among the six species of Listeria, only Listeria monocytogenes is the major human pathogen that causes disease in humans. It is a causative agent to cause listeriosis, a serious infection caused by ingesting the food contaminated with Listeria. The optimum temperature for growth is 30 to 37 degree Celsius, within this…

In August 2011, 15 people became ill and were hospitalized with what was later identified as Listeriosis. Listeriosis is the result of an infection of Listeria monocytogenes, a bacteria commonly found in soil, water and decaying vegetation. L. monocytogenes can reside in the GI tract and vagina while the host remains asymptomatic and is not normally a cause of illness in the general population. Persons most at risk for Listeriosis are people with weakened immune systems which includes the…

applied to your label means that your company has satisfied the fastidious requirements expected from our regional populations. This behavior was illustrated when one of the most iconic brands manufactured in Texas, Blue Bell ice cream experienced a listeria outbreak forcing the company on April 20th, 2015 to close its manufacturing facilities for four months, and endure a massive negative publicity campaign. The rewards of attaining the term icon payed dividends immediately upon Blue Bell…

plant is contaminated. One example of this type of outbreak was the Blue Bell ice cream listeria outbreak in the US this past year (CDC, 2015). This particular outbreak spanned the American West and Midwest, in Arizona, Kansas, Oklahoma, and Texas and occurred over the course of 5 years. Each instance of Listeria could be traced back to a Blue Bell production line in Brenham Texas. There were only 10 cases of listeria in this outbreak, but it provides an illuminating illustration of how modern…

the continuing theme of the organization focused on a few key points for its target audience. Those key points Blue Bell focused on included: - Finding the root cause of the listeria contamination that were found in some of Blue Bell’s ice creams. - Bringing in a microbiologist to the production plants to monitor for any listeria that could potentially show up in another case of Blue Bell ice cream carton. - Conduct a “test and hold” program to ensure Blue Bell…

4. Risk Assessment Issues The risk assessment in any industry is very important, can use to direct potential intervention strategies at different food processing steps. in this case, the risk of Listeria monocytogenes can be potential sources of contamination from milk source especially if this cheese made from raw milk and by traditional methods and manufacturing process, and this happened in this case, one of main source of hazards in Lanark Blue cheese by used of Ewes raw milk. According to…

If the turkey is left out for nine hours in a room temperature environment, then there will be 10% more bacteria on it than on the ham and 20% more bacteria than on the bologna. The idea of this experiment is to test which lunch meat will attract more bacteria within a three day incubation period after being left out for nine hours. This project is interesting because bacteria growth on leftovers that have not been refrigerated has always interested me. Many people will leave out food, throw it…

diarrhoea has resolved. Listeria bacteria: it is a bacterium which causes listeriosis. It is a gram-positive coco bacillus bacterium. It is aerobic and tolerant to acid-salt and cold. According to the web (http://www.food.gov.uk>microbiology) number of cases of listeriosis is lower than salmonella and campylobacter. This disease places a big responsibility for public health and economics in UK because of high hospitalization and mortality rate. Most people infected with listeria are…

Listeriosis is predominantly a food-borne illness caused by the ubiquitous Gram-positive bacterium Listeria monocytogenes, initially recognized as a foodborne pathogen in the early 1980s. People most prone to the disease are pregnant women, newborns, elderly, and those with HIV or other diseases that compromise immunity. Listeria infections are associated with a high mortality rate, thus effective treatment and prevention are essential. Antimicrobial therapy Successful treatment of…

charge of ice cream. When the researcher came home that day and opened the freezer, they saw a half gallon of Blue Bell Vanilla ice cream. It confirmed to the group the fact that despite the three deaths and multiple cases of sickness from the 2015 listeria outbreak, most consumers did not hesitate to purchase the product…
