Listeria monocytogenes

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…

1. INTRODUCTION Electrochemical Impedance Spectroscopy is an effective method of analyzing the intricate electrical resistance of a process and it is sensitive to surface phenomena and changes in the bulk properties. Thus it plays a major role in electrochemical research. It has been diligently used for the interpretation of corrosion mechanisms and in the characterisation of charge transport over the membrane. In the area of biosensors, it is especially appropriate for the detection of…

Potential Hazards in pies Ingredients Potential Pathogens Process Control Fruits and vegetables Salmonella spp., Shigella spp., enterohemorrhagic Escherichia coli, Listeria monocytogenes, Bacillus cereus, Clostridium botulinum,…

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…

The main advantage of eating pasteurized cheeses is simply that it is healthier for you to consume than unpasteurized cheeses. This is because during the pasteurization process, when the milk is heated to between one-hundred-and-forty to one-hundred-and-fifty degrees Fahrenheit and then cooled to fifty-five degrees Fahrenheit, any pathogens like harmful bacteria in the milk are killed. You are less at risk of contracting salmonella and E.Coli if you consume pasteurized cheeses. However, though…

One of the leading causes of bacterial meningitis is Neisseria meningitidis, which can be acquired globally. N. meningitidis is normal flora in the human nasopharynx, but if an individual becomes susceptible, it can lead to bacterial meningitis. Incidence of N. meningitidis is strongly influenced by age. Infants have the highest risk for meningococcal disease. Low serum bactericidal antibody levels play a large role in those that are at risk for infection. Those with compromised immune…

Bacterial Meningitis Meningitis is an infection that affects meninges, membrane coverings of the brain and spinal cord. Due to Bacterial meningitis’ close proximity to the brain and spinal cord it is potentially life threatening. If not treated promptly it may lead to life-long complications such as deafness, epilepsy, hydrocephalus and cognitive deficits. Bacterial meningitis is contagious and prolonged close contact can spread the bacteria that cause meningitis. The bacteria can spread from…

One of the most frightening things about certain diseases is that they can seemingly occur for no reason. You couldn’t have done anything to prevent it, and there was nothing you could have done differently. Other times, diseases can be caused by taking preventative precautions, receiving vaccinations, making healthy lifestyle choices, or avoiding particular situations. Meningitis is a disease that can encompass many of those factors. You may come across many different forms of meningitis,…

The 1918 “Spanish flu” Pandemic was caused by an avian-like influenza virus that gained the ability for efficient and sustained human-to-human transmission and then spread globally, killing 20-50 millions. Fortunately, viruses with pandemic potential are rare occurrences and ongoing surveillance of human and avian viruses is being done globally in preparedness for an influenza pandemic. Vaccines and anti-viral drugs may be available, if needed and time permits. Both kinds of therapies have…
