Status of microbial based cleaning products in statutory regulations and ecolabelling in Europe, the USA, and Canada.

ABSTRACT: Cleaning products containing living microorganisms as active ingredients are increasingly being used in household, professional and industrial cleaning applications. Microorganisms can degrade soiling associated with dirt, food residues, and grease by enzymatic and metabolic action and out-compete microorganisms associated with odor problems. Their potential for odor control seems to result in a competitive advantage over conventional chemically-based cleaning products. Moreover, producers of microbial-based cleaning products (MBCPs) claim that their products are less harmful to the environment. These promising prospects have triggered interest from consumer and environmental organizations, professional users, and regulators in understanding if there are also possible negative health and environmental impacts which require attention and how the safety of these products is ensured. Unfortunately, there is little information on these issues in the public domain. Moreover, regulatory oversight in Europe is essentially limited to pathogenic properties in the context of worker protection. Canada, in contrast, has a regulatory framework in place to assess risks to human health and the environment from the manufacture, import and/or use of new microorganisms contained in MBCPs. In the absence of mandatory standards, safety assessment and hygienic practices seem to vary considerably across companies. Recently developed ecolabelling standards are - for the time being - the only option for transparent compliance to minimum standards in terms of safety as well as assessments of manufacturer information by third parties. These standards highlight in particular the need for precise taxonomic information for assessing the pathogenic properties and the need to ensure the absence of potentially harmful microorganisms as contaminants. Ecolabelling standards are, however, voluntary and do not cover all relevant safety issues. In order to develop a more comprehensive set of mandatory standards for health and safety, a number of areas would benefit from further research (e.g. the role in plant pathogenicity and other environmental properties of the microorganisms used; the relevance of chronic exposure to dusts and aerosols containing vegetative cells and spores; the relevance of strains which belong to species known to include opportunistic pathogens and possible hazards for particularly sensitive risk groups). Improved knowledge in these areas will contribute to a predictable level of product safety.

Project description:BackgroundHealthcare-Associated Infections (HAIs) are one of the most frequent complications occurring in healthcare facilities. Contaminated environmental surfaces provide an important potential source for transmission of many healthcare-associated pathogens, thus indicating the need for new and sustainable strategies.AimThis study aims to evaluate the effect of a novel cleaning procedure based on the mechanism of biocontrol, on the presence and survival of several microorganisms responsible for HAIs (i.e. coliforms, Staphyloccus aureus, Clostridium difficile, and Candida albicans) on hard surfaces in a hospital setting.MethodsThe effect of microbial cleaning, containing spores of food grade Bacillus subtilis, Bacillus pumilus and Bacillus megaterium, in comparison with conventional cleaning protocols, was evaluated for 24 weeks in three independent hospitals (one in Belgium and two in Italy) and approximately 20000 microbial surface samples were collected.ResultsMicrobial cleaning, as part of the daily cleaning protocol, resulted in a reduction of HAI-related pathogens by 50 to 89%. This effect was achieved after 3-4 weeks and the reduction in the pathogen load was stable over time. Moreover, by using microbial or conventional cleaning alternatively, we found that this effect was directly related to the new procedure, as indicated by the raise in CFU/m2 when microbial cleaning was replaced by the conventional procedure. Although many questions remain regarding the actual mechanisms involved, this study demonstrates that microbial cleaning is a more effective and sustainable alternative to chemical cleaning and non-specific disinfection in healthcare facilities.ConclusionsThis study indicates microbial cleaning as an effective strategy in continuously lowering the number of HAI-related microorganisms on surfaces. The first indications on the actual level of HAIs in the trial hospitals monitored on a continuous basis are very promising, and may pave the way for a novel and cost-effective strategy to counteract or (bio)control healthcare-associated pathogens.

Project description:BACKGROUND:In recent years, cleaning has been identified as an occupational risk because of an increased incidence of reported respiratory effects, such as asthma and asthma-like symptoms among cleaning workers. Due to the lack of systematic occupational hygiene analyses and workplace exposure data, it is not clear which cleaning-related exposures induce or aggravate asthma and other respiratory effects. Currently, there is a need for systematic evaluation of cleaning products ingredients and their exposures in the workplace. The objectives of this work were to: a) identify cleaning products' ingredients of concern with respect to respiratory and skin irritation and sensitization; and b) assess the potential for inhalation and dermal exposures to these ingredients during common cleaning tasks. METHODS:We prioritized ingredients of concern in cleaning products commonly used in several hospitals in Massachusetts. Methods included workplace interviews, reviews of product Materials Safety Data Sheets and the scientific literature on adverse health effects to humans, reviews of physico-chemical properties of cleaning ingredients, and occupational hygiene observational analyses. Furthermore, the potential for exposure in the workplace was assessed by conducting qualitative assessment of airborne exposures and semi-quantitative assessment of dermal exposures. RESULTS:Cleaning products used for common cleaning tasks were mixtures of many chemicals, including respiratory and dermal irritants and sensitizers. Examples of ingredients of concern include quaternary ammonium compounds, 2-butoxyethanol, and ethanolamines. Cleaning workers are at risk of acute and chronic inhalation exposures to volatile organic compounds (VOC) vapors and aerosols generated from product spraying, and dermal exposures mostly through hands. CONCLUSION:Cleaning products are mixtures of many chemical ingredients that may impact workers' health through air and dermal exposures. Because cleaning exposures are a function of product formulations and product application procedures, a combination of product evaluation with workplace exposure assessment is critical in developing strategies for protecting workers from cleaning hazards. Our task based assessment methods allowed classification of tasks in different exposure categories, a strategy that can be employed by epidemiological investigations related to cleaning. The methods presented here can be used by occupational and environmental health practitioners to identify intervention strategies.
