To evaluate the effectiveness of the chulli water purifier, a new household water treatment strategy in Bangladesh that relies on passing water through a stove, we interviewed persons who had this water purifier. From households using it regularly, we tested untreated water, sand-filtered water without heat pasteurization, sand-filtered and heat pasteurized water, and household stored, treated ...

In the 19th century, milk from diseased cattle produced in unsanitary surroundings and distributed under filthy conditions to an increasingly urbanized population sickened and killed consumers by the thousands (1,2). Wide acceptance of the germ theory and the sanitary awakening that followed led to vast improvements in animal health and hygiene, and the safety of dairy products improved substan...

There is clearly a significant increase in awareness of the risks from food-borne diseases among consumers in western countries in the past decade. The concern about the quality and safety of food appears to be driven by increased affluence, new scientific discoveries, by more sophisticated measurements and analyses, by new information about linkages between diet and health, by new food technol...

ABSTRACT Systematic studies were conducted to elucidate the role of different soil microbial groups in the development of apple replant disease. Populations of targeted microorganisms were reduced by the application of semiselective biocides and soil pasteurization. Bacteria were not implicated in the disease, because application of the antibiotic chloramphenicol reduced soil populations of bac...

Concentrated high intensity electric field (CHIEF) is non-thermal pasteurization technology that uses microsecond pulses of electricity to inactivate bacteria without causing undesirable changes in flavor or quality of a product. This technology was explored as an alternative to current milk pasteurization processes, and was examined for its effects on microbial stability, sensory, quality and ...
