“…Thus, the application of lysozyme in active packaging targets mainly inhibition of the major Gram-positive pathogenic bacteria, such as L. monocytogenes (Duan, Park, Daeschel, & Zhao, 2007;Min, Harris, Han, & Krochta, 2005). L. monocytogenes is a very critical food pathogen for dairy products due to its high incidence in raw milk and capacity to grow at refrigeration temperatures (Kozak, Balmer, Byrne, & Fisher, 1996). Although fresh cheeses are mostly produced by using pasteurized milk, several listeriosis outbreaks associated with the consumption of cheeses made from pasteurized milk have also been reported due to improper pasteurization or post-contamination (de Castro et al, 2012;Jackson et al, 2011;Johnsen, Lingaas, Torfoss, Strøm, & Nordøy, 2010;Yde et al, 2012).…”

The antimicrobial and antioxidant potential of zein and zein-wax composite films having different release profiles for lysozyme and mixture of lysozyme, catechin and gallic acid were tested on cold-stored fresh Kashar cheese inoculated with Listeria monocytogenes ATCC 7644. All lysozyme containing films prevented the increase of L. monocytogenes counts in Kashar cheese for 8 weeks at 4°C, but it was only the zein-wax composite films with sustained lysozyme-release rates which caused a significant reduction (−0.4 decimals) in initial microbial load of inoculated cheese samples. The mixture of catechin and gallic acid improved the in vitro antimicrobial effect of films against L. monocytogenes, but showed no considerable antimicrobial effect in cheese. However, the films containing catechin and gallic acid were effective in preventing oxidative changes in cheese. This study showed the possibility of increasing safety and quality of fresh cheeses by use of active packaging employing natural antimicrobial compounds and controlled release technology. Industrial relevance: There has been a growing interest to develop the functional properties of packaging materials and to obtain packed foods with better shelf-life and quality. Active packaging incorporating antimicrobials is one of the most promising areas since application of this method can improve safety of foods by inhibiting pathogenic bacteria or controlling spoilage flora by using minimum amounts of active compounds. Recently, health concerns of consumers and environmental problems related to plastics increased the popularity of using natural antimicrobial substances in edible films and coatings. This work employs a GRAS status natural antimicrobial lysozyme and zein a major by-product of rapidly growing oil and bioethanol industries which can form self-standing films, coatings or casings. The results of this study showed the possibility of using flexible antimicrobial and antioxidant films with controlled release properties in diary industry.

“…The primary mode of infection is through the ingestion of contaminated food. Therefore, contamination of milk and milk products with L. monocytogenes is a serious problem to the world (Kozak et al, 1996;Donnelly, 2004;Rudolf and Siegfried 2001;Conly and Johnston, 2008;Pan et al 2006;Molla et al, 2004).…”

Listeria monocytogenes is the causative organism of listeriosis, which primarily affects immunecompromised individuals, including pregnant women. Contamination of milk and milk products with L. monocytogenes is a serious problem to the world and to the developing countries like Sri Lanka. Even the presence of low numbers of L. monocytogenes is a potential risk since this organism is capable of multiplying at ambient and under refrigerated conditions. The main aim of the study is to detect the circulating serotypes in dairy industries using molecular methods and primarily to trace the lineage of these serotypes with a focus on food safety and disease prevention. Altogether total of 266 samples from raw milk, pasteurized milk, ice cream, curd, yogurt and cheese were collected from many parts of the country, tested for the presence of L. monocytogenes and studied the serotype. L. monocytogenes was detected in all types of the above-mentioned milk and milk products. Out of total L. monocytogenes strains detected by PCR, 61.51%, 11.53% and 4% belong to serotypes 1/2a (or 3a) [lineage II], 1/2b (or 3b) [lineage I] and, 1/2c (or 3c) [lineage II] respectively. It has been observed previously that serotypes (1/2a), 1/2b) isolated from raw milk samples been linked to multiple human listeriosis outbreaks. This study revealed the serotypes of L. monocytogenes circulating in Sri Lanka, thus makes an alarm to the health authorities to be more vigilant about the probable outbreaks of listeriosis in Sri Lanka. This is the first report on circulating L. monocytogenes serotypes in Sri Lanka.All copyrights reserved to Nexus® academic publishers

“…The literature is plenty of data on diseases caused by pathogenic microorganisms like Listeria monocytogenes and Salmonella associated to raw milk or raw milk based dairy products (6,12,14,18,19,20,25). Data concerning foodborne diseases caused by raw milk and derivatives in Brazil are inconsistent (10).…”

Fluctuations in the Brazilian milk market force small milk producers to find temporary trade alternatives, which include selling raw milk to people who prefer this type of milk rather than heat-processed milk. Considering the importance of these small milk producers to the market and the well-known health risks associated to consumption of raw milk, this study evaluated the microbiological quality and the presence of Listeria monocytogenes, Salmonella spp., chlorine, antimicrobials and insecticides (organophosphates and carbamates) in raw milk produced in 210 small and medium farms located in four important milk-producing Brazilian states (Paraná, São Paulo, Minas Gerais and Rio Grande do Sul). In 66% of the selected farms the milking was manual. In 33% of them, the milking was semi-automatic, and only 1% were equipped with fully automatic milking systems. All raw milk samples were negative for L. monocytogenes, Salmonella spp and chlorine. Mesophilic aerobes counts were higher than 10 5 CFU/ml in 75.7% of the samples. In 80.4%, coliforms were over 10 2 CFU/ml. Escherichia coli was detected in 36.8% of the samples. Insecticides and antimicrobial residues were observed in 74.4% and 11.5% of the samples, respectively. The presence of unacceptable levels of hygiene indicators, insecticides and antimicrobial residues were considered more important risk factors than the two pathogens.
