This book emphasizes the occurrence of sublethal injury in the indicator and pathogenic bacteria commonly encountered in foods, water and feed and modifications of the currently recommended methods for the effective detection of these bacteria. Chapters include methods for recovering injured ''classical'' enteric pathogenic bacteria from foods and for recovering injured pathogenic organisms from animal food. Detection and significance of injured indicator and pathogenic bacteria in water are explained, as well as detection of injured sporeforming bacteria from foods. This volume is extremely useful for individuals in the academic institutions, industries, federal and state regulatory agencies, public health service and hospitals who are interested in effective detection of indicator and pathogenic bacteria in food and water.
