Ultimately, field investigators in California found a strain of E. coli in cattle feces that was identical to the bacterium in the tainted spinach, but the precise method of contamination was unknown.
The EN1500 method of contamination did not allow for hands to be sufficiently dry to adequately test smaller volumes of ABHR, typical of healthcare practitioner use.
A hybrid method consisting of the ASTM E2755 method of contamination with an EN1500 method of recovery resulted in baseline recoveries of Escherichia coli K12 that were relatively low (mean log10 precount of 5.57; standard deviation 0.615).
Therefore, further studies on methods of reducing contamination should be conducted in the slaughter places.
Variables within the European Standard EN1500 (Hygienic Handrub) method and ASTM standard E2755-10 method, including methods of hand contamination and modes of recovery, were tested on their ability to provide a consistent, robust method for testing ABHR.
We discuss the strengths and limitations of the current methods of addressing treatment contamination and the contamination adjusted intention to treat technique, provide examples of effective uses, and discuss how using estimates generated by contamination adjusted intention to treat analysis can improve clinical decision making and patient care.
Types of fish consumed (lean, fatty, shellfish), dietary factors in fish, as well as preparation methods and levels of contamination, which could vary across different countries, should be comprehensively investigated when the potential role of fish and long-chain n-3 fatty acids in the development of type 2 diabetes is examined in future studies.
Recent CR research has focused on developing efficient methods of metal-contaminant separation to prevent contamination of treated water by dosing recovered coagulant.
To determine the most effective and consistent method for control of contamination during hydrolysate production, we compared hydrolysates made from autoclaved AFEX-pretreated feedstocks to those made from non-autoclaved pretreated feedstocks, for which microbial growth was controlled by the addition of antibiotics during the enzymatic hydrolysis.
Using time-correlated spectroscopy methods the fluorescence detection of contamination levels on surfaces is possible even if the fluorescence spectra of contamination and base material overlap.
