  • Anaerobic Digestion Reduces Microplastics in Sludge

    Anaerobic digestion can help remove microplastics — a large cause of water pollution — during the sewage treatment process Microplastics, or tiny fragments of plastic, include microbeads, the plastic pellets present in thousands of household and personal care products, including toothpaste, cosmetics, and beauty scrubs. They also include fragments from the breakdown of anything in our ...

  • Evaluation of Sludge Treatments for Pathogen Reduction

    The recycling to agricultural land is an important outlet for sewage sludge and other sludges but it must be controlled in order as to obtain agricultural benefit from the sludge whilst protecting human and animal health and the environment at large. Current practices in Europe are based on the requirements of the 1986 Directive on the use of sewage sludge in agriculture (86/278/EEC). Since that ...


  • The role of process water in pathogen reduction

    The USDA’s Pathogen Reduction/Hazard Analysis and Critical Control Point (HACCP) rule in July of 1996 required all meat and poultry slaughter plants to adopt a system of process controls to prevent food safety hazards. It contained four components: standard operating procedures (SOPs) for sanitation, HACCP plans, generic E. coli testing and Salmonella performance standards. With the ...

  • An estimate of the cost of acute health effects from food- and water-borne marine pathogens and toxins in the USA

    Large and growing segments of the United States population consume seafood or engage in marine recreation. These activities provide significant benefits but also bring risk of exposure to marine-borne illness. To manage these risks, it is important to understand the incidence and cost of marine-borne disease. We review the literature and surveillance/monitoring data to determine the annual ...

  • Rapid, sensitive, and specific immunomagnetic separation of foodborne pathogens

    Food defence requires the means to efficiently screen large volumes of food for microbial pathogens. Even rapid detection methods often require lengthy enrichment steps, making them impractical for this application. There is a great need for rapid, sensitive, specific, and inexpensive methods for extracting and concentrating microbial pathogens from food. In this study, an immunomagnetic ...

  • Fate of pathogen indicators in a domestic blend of food waste and wastewater through a two-stage anaerobic digestion system

    Anaerobic digestion is a viable on-site treatment technology for rich organic waste streams such as food waste and blackwater. In contrast to large-scale municipal wastewater treatment plants which are typically located away from the community, the effluent from any type of on-site system is a potential pathogenic hazard because of the intimacy of the system to the community. The native ...

  • Evaluation of major types of shiga toxin 2e-producing escherichia coli bacteria present in food, pigs, and the environment as potential pathogens for humans

    Shiga toxin 2e (Stx2e)-producing strains from food (n = 36), slaughtered pigs (n = 25), the environment (n = 21), diseased pigs (n = 19), and humans (n = 9) were investigated for production of Stx2e by enzyme-linked immunosorbent assay, for virulence markers by PCR, and for their serotypes to evaluate their role as potential human pathogens. ...

  • Effects of lactic acid bacteria (LAB) on the survival and growth of some food-borne pathogens in fermenting wakalim, a traditional Ethiopian fermented beef sausage

    Wakalim is spiced naturally fermented traditional beef sausage in Ethiopia. During its fermentation using pure starter cultures of Lactobacillus plantarum1 or Pediococcus pentosaceus1 and mixture of the two starters, the counts of Salmonella typhimurium DT104 and Escherichia coli dropped sharply after 12 h of fermentation and complete elimination was noted on the third or fourth day. The count of ...

  • Food industry case study

    Automation and mechanisation are key requirements in high throughput environments such as analytical laboratories. The implementation of Autoscribe.s Matrix LIMS at Westward Laboratories in Cornwall together with Kiestra Lab Automation (The Netherlands) systems demonstrates how such projects, can lead to increased productivity, reduced human errors, and improved tracking and traceability. ...

  • On-Site Food Waste Pretreatment

    Guide to equipment and systems for businesses, institutions and venues that manage food waste on-site. Businesses, institutions and venues that generate large volumes of food waste have an increasing number of options to manage this organics stream, starting with tools and knowledge to prevent and reduce what is generated in the first place, followed by donation of excess and prepared ...

  • Role of irradiation treatment in the food industry

    Irradiation from radioactive elements, such as cobalt-60, or an electron beam, can be applied to raw materials to prevent the proliferation of plagues or to kill bacteria that could be present in ready-to-eat foods or industrialised ingredients. It is therefore an important tool in food safety and food security. Food contamination by some pathogenic bacteria, such as Salmonella sp. or Escherichia ...

  • Differences in household attitudes on food defence and food safety: an international comparison

    This paper reports results from a large, six-nation, internet-based survey of consumer attitudes toward food safety and food defence administered during the fall of 2008. Responses were obtained from separate samples of approximately 1,000 each in Germany, Italy, Japan, Spain, the UK, and the USA. Food defence was generally a greater concern, and respondents were less confident that their food ...

  • Explaining differential sources of zoonotic pathogens in intensively-farmed catchments using kinematic waves

    Surveys in streams draining intensively farmed catchments can, during flood events, indicate differential time-concentration patterns between a bacterial health-risk indicator (E. coli) and a major zoonotic pathogen that it seeks to indicate—Campylobacter. The indicator's peak concentration at a monitoring station can arrive ahead of the flood peak (the pollutograph ...

  • Shining a Light on the Food and Beverage Industry

    As published in this months edition of Process & Control, Diane White discusses how UV systems can provide a practical, power saving alternative to pasteurisation in food and beverage production Waterborne micro-organisms are responsible for adverse effects on flavour, colour, odour and shelf life of products and, of course, potential health risks to consumers. A number of emerging ...

  • Advanced Water Treatment Solutions for the Food/Beverage Industry

    The agricultural/irrigation industry is one of the most demanding users of water for process applications. The availability of a sustainable supply of clean water is a necessity. Water shortages, reduction of water quality, and environmental issues, have led to an increased awareness of the use of both treated waste water as well as the ...

  • Evaluating Food Digestion Effluent For Landscape Use

    Over the last year, Loyola Marymount University (LMU) has installed and studied a food waste diversion technology that converts raw food waste into a liquid effluent that is disposed through the sewer system. As an urban university located in West Los Angeles, California, LMU faces two major barriers with respect to composting food waste: on-campus space constraints and long distances to off-site ...

  • Land application of sewage sludge (biosolids) in Australia: risks to the environment and food crops

    Australia is a large exporter of agricultural products, with producers responsible for a range of quality assurance programs to ensure that food crops are free from various contaminants of detriment to human health. Large volumes of treated sewage sludge (biosolids), although low by world standards, are increasingly being recycled to land, primarily to replace plant nutrients and to improve soil ...

  • Microbiological quality of ice and ice machines used in food establishments

    The ice used in the food industry has to be safe and the water used in ice production should have the quality of drinking water. The consumption of contaminated ice directly or indirectly may be a vehicle for transmission of pathogenic bacteria to humans producing outbreaks of gastrointestinal diseases. The objective of this study was to monitor the microbiological quality of ice, the water ...
