  • 9 Methods to Identify and Detect Microbial Contaminants in

    RisksPurposePrognosisInfluencesAssessmentApplicationsSignificanceCauseToxicityEnvironmentEvolutionOther animalsControversyDiagnosisPreparationPropertiesIntroductionScopeTypesAdvantagesMechanismVariationsConstructionSynthesisOthersUseThe transmission of infectious diseases via contaminated water continues to be a risk to public health in the United States and throughout the rest of the. world. Source and finished drinking waters are vulnerable to microbial pathogen contamination from a variety of sources of human and animal fecal wastes and from the introduction and proliferation of nonfecal pathogenic microbes. Throughout most of the modem history of drinking water supply, concerns about pathogenic microbes have focused on enteric bacteria of human fecal origin. These concerns led to the development of criteria and standards for bacteriological quality intended to protect against excessive risks from enteric bacterial pathogens such as Salmonella typhi and other nontyphoid Salmonella spp., Shigella spp., and Fibrio cholerae. The infectious disease risks in drinking water supplies from enteric viruses (such as hepatitis A virus), enteric parasites (such as Entamoeba histolytica and Giardia lamblia), and nonfecal bacterial pathogens (such as Legionella spp.) were not recognized until more recent times. These risks were recognized initially by the occurrence of waterborne outbreaks of disease mused by these pathogens. animals, often asymptomatically, and some, such as the Legionella spp., the Mycobacteria spp., and the heterotrophic plate count bacteria, have abiotic environmental reservoirs. For many of these bacteria the role of waterborne transmission has been documented by waterborne outbreaks, or it is strongly suspected because the bacteria have been detected in drinking water and its sources (see Table 9-2). In the case of some of these waterborne bacteria their risks to human health from ingestion or inhalation of water or contact with water are uncertain because they have not been conclusively documented by outbreaks or other epidemiological evidence of waterborne disease. However, their presence in drinking water and the uncertainty of their risks to human health from drinking water exposure suggest the need for further investigation and analyses. The risks posed by various bacteria potentially present in drinking water differ among the various genera and species as well as within the same genus and species of a bacterium. These differences in risks to human health pose considerable challenges to the detection and identification of these bacteria in water. Similar concerns apply to the protozoan parasites, algae, and fungi. Strains or variants of the same genus and species of bacterium can differ dramatically in their ability to cause disease because this ability is largely dependent on the presence of virulence factors or properties.

    Influencing The NeedMetal Detection and X-RayNew Improvements and CapabilitiesCost, Life Expectancy and Other ConsiderationsIn today’s food and beverage processing operations, ensuring all food and beverage products are free of potential foreign material is critical for processors. That process begins even before ingredients and materials are used in your facility. “Contamination threats exist at all steps of the food chain, so it is up to processors to protect consumers from the start,” says Bob Ries, lead product manager of X-ray inspection and metal detection for Thermo Fisher Scientific. Keeping products free of contaminants is important for protecting a food and beverage company’s reputation and the consumer, of course, but it is also crucial for the operation’s food safety plan. “Retailers are increasingly wary of protecting the reputation of their brands, as product recalls can be extremely damaging and very costly,” says Christy Draus, marketing manager for Eagle Product Inspection. “Consumer expectations, too, continue to be high due to the sheer amount of information that is available to them.”...
