📰 Selected Aspects of the Antibacterial Use of Lactic Acid in Food Processing ✍ Dragica Đurđević-Milošević, Andrijana Petrović, Vesna Kalaba, Milka Stijepić and Gordana Jovanović L(+)-lactic acid is authorized as an active substance for biocidal products, with applications in veterinary hygiene, food, and animal feed. Several factors can influence the antimicrobial effect of lactic acid, including the applied concentration of lactic acid, the contact time, and the organic soiling of the surface to which it was applied. The aim of this study was to evaluate the bactericidal activity of 5% (v/v) and 1% (v/v) lactic acid solutions on test bacteria: the Gram-negative strain Salmonella enterica subsp. enterica serovar Typhimurium (ATCC 14028) and the Gram-positive Staphylococcus aureus subsp. aureus (ATCC 33592), which is a strain that is resistant to gentamicin and methicillin (MRSA). A dilution–neutralisation method was used, based on a quantitative suspension test EN 1276, for the evaluation of the bactericidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic, and institutional areas, with the bacterial activity being modified in part of the obligatory test organisms. The obtained results showed no difference in the results of the tests under simulated clean and dirty conditions. Both tested lactic acid concentrations showed a 5 lg reduction in Salmonella Typhimurium. For the tested strain, Staphylococcus aureus (MRSA), the required reduction of 5 lg was not achieved. These results contribute to a better understanding and rationale for the use of lactic acid for antibacterial purposes. 🔗 Read the paper at https://lnkd.in/gx3bNTJy. #bactericidalactivity #lacticacid

The most comprehensive report on thymol/carvacrol fibrous structures prepared with Prof. Minoo Naebe's Team! Food safety and hygiene section covers not only the food coating/packaging, but also the entire food chain including plant protection in agriculture, transportation, and storage of food/crops. This section also contains all food hygiene-related (veterinary, feed additives for animal production, dietary supplements, and food processing) applications. Looking at the human health applications, outside body applications, which are mainly limited to wound healing, have been substantially widened to hygiene & preventive/protective care and comfort & well-being applications. In the case of comfort and protective care, not only the insect repellent but also other important parasite repellent fibrous structures have been mentioned. Inside body applications (tissue engineering and drug delivery) have been diversified to the uttermost extent by giving some uncommon fabrication methods and applications. #minoonaebe, #thymol, #carvacrol, #fibrous, #antibiofilm, #antiviral, #insecticidal, #antimalaria, #antimite, #antitick, #antitoxoplasmosis, #antileishmaniasis https://lnkd.in/dzPtXgCe

The MICROBES CONTAM SWABS is a series of diagnostic tools that include a culture medium for the direct assessment and identification of microbial presence on various work surfaces. These tests are designed for easy and direct application to areas suspected of contamination, allowing for the quantification (microbial count) and identification of microbes present. It is a valuable resource in environments requiring strict microbial management, such as laboratories, healthcare facilities, food processing plants, and other areas where cleanliness and sterility are crucial. By providing a straightforward method for monitoring surface cleanliness, the MICROBES CONTAM SWABS series help in maintaining hygiene standards and preventing microbial contamination. Benefits of Using the MICROBES CONTAM SWABS series tests: 1. Ease of Use: The tests are straightforward to administer directly on work surfaces without the need for specialized training, making it accessible for routine monitoring. 2. Clear Color Changes: The culture mediums are designed to exhibit noticeable color changes in the presence of microbial growth, simplifying the interpretation of results. 3. No Additional Reagents Required: These self-contained tests eliminate the need for external reagents, streamlining the testing process and reducing potential errors. 4. Rapid Results: Results can be obtained within 18 to 24 hours, enabling quick decision-making regarding cleanliness and the need for disinfection. 5. Sensitive Detection: With a detection limit of 10 colony-forming units (CFU) per milliliter, the tests are highly sensitive, ensuring even low levels of microbial contamination can be detected. Available microbes kits: Salmonella, Listeria, E.coli - Coliforms, Microbial Growth #microbes #microbiology #fooddiagnostics #listeria #salmonella #ecoli #coliforms #microbialgrowth #menidimedica

I guess it's OK to claim "Best in Class", when your product is - in fact ... "Best in Class" ;-) >>The calculated accuracies for BG and GR+ of the BACT test were 89% and 91%, respectively. This is comparable to the reported test characteristics of other commercially available on-farm rapid test devices for clinical mastitis in dairy cows like the Accumast (85% accuracy)- (Ganda et al., 2016), the MastDecide (79% accuracy) (Leimbach and Krömker, 2018), VétoSlide (74% accuracy) and the VétoRapid (81% accuracy) ...<< Just out yesterday: https://lnkd.in/dmFJzWiu

Great peer-reviewed work (Corrigan et al. Microorganisms. 2024), showing that dietary supplementation of yeast mannan-rich fraction (MRF [Actigen]) can positively impact the performance of laying hens, lower relative abundance of Escherichia, Brachyspira, and Trueperella, and their antimicrobial resistance encoded genes under commercial conditions. We continue to learn about the multiple benefits of MRF supplementation in commercial livestock production. Link to the full article:
