HPP is helping to reduce the risks associated to Listeria<\/em> monocytogenes<\/em> in food industry<\/strong><\/h2>\n

The South African listeriosis outbreak is still ongoing but hopefully soon resolved. Local officials working alongside Listeria monocytogenes <\/em>experts have traced the pathogen to its source, a meat processing facility<\/a>. So far, this has been the biggest reported listeriosis outbreaks in the world (around 1,000 infected people and 180 deaths), and it could be a reminder that no food processing facilities are exempt of involuntarily hosting Listeria monocytogenes<\/em>. Therefore, controlling this pathogen is a priority, and HPP technology can be part of the solution.<\/p>\n

Since the 80\u2019s, Listeria monocytogenes<\/em><\/a> is considered to be a major foodborne pathogen after the coleslaw outbreak in 1981. Despite the knowledge in controlling this pathogen’s growth, the number of case reports of listeriosis has increased year by year around the globe. Most cases are reported in countries with high gross national income, but it is not clear whether the differences reflect true geographical differences, food habits and handling, or differences in diagnosis and reporting practices, according to FAO<\/a>. For instance, around 2,500 human cases confirmed (0.47 cases per 100,000 population) were reported in Europe<\/a> during 2016, which represented a 9.3 % increase compared with 2015. The EU hospitalization rate (97 %) and the case\u2010fatality rate (16 %) was the highest among all zoonosis reported in 2016. In United States, the epidemiological data reported similar values<\/a> to European for the same period. The pathogen causes serious localized and generalized infections depending on the affected patient. In healthy adults, listeriosis is mainly manifested as diarrhea and fever, whereas the disease is severe for the most susceptible groups: pregnant women, newborns and immunocompromised people (people with transplant, cancer or AIDS, diabetes, alcoholism and over 65 years old).<\/p>\n

The recent outbreaks<\/a> and increasing number of product recalls<\/a> have made the control of this pathogen a worldwide concern in fruit and vegetables<\/a>, dairy<\/a>, meat products<\/a> (even cured meats<\/a>) and other foods. L. monocytogenes <\/em>can be found in most of raw materials, processing lines and final products. Therefore, every food establishment is vulnerable to hold Listeria <\/em>in their processing machines right through the premises. As food is the primary source of Listeria monocytogenes,<\/em><\/a> its control along food chain is absolutely necessary. According to ILSI<\/a>, foods for causing listeriosis<\/a> are characterized by:<\/p>\n
