Enteric virus survival during household laundering and impact of disinfection with sodium hypochlorite

Article Abstract:

Enteric viruses added to cotton cloth swatches survive the wash cycle, the rinse cycle, and a 28-min permanent press drying cycle commonly practiced in households in the U.S. is conducted. It is demonstrated that addition of sodium hypochlorite with detergent significantly reduces the number of enteric viruses on the swatches after washing and drying by at least 99.99 percent.

Prevalence of Salmonella spp. in oysters in the United States

Article Abstract:

A study was conducted to determine the prevalence of Salmonella spp. in oysters harvested from 36 U.S. bays. No relationship was found between the isolation of fecal coliforms and Salmonella from oysters, indicating a necessity for specific monitoring for Salmonella and other pathogens rather than the current reliance on fecal coliform testing.

Comparative inactivation of adenovirus serotypes by UV light disinfection

Article Abstract:

The results confirm that adenoviruses are the most resistant enteric viruses in activation by UV light and that adenovirus 40 appears to be the most resistant. The effect of freeze-thawing and storage in water may affect the sensitivity of some adenoviruses to activation by UV light.
