Disinfection of hatching eggs by formaldehyde fumigation – a review Desinfektion von Bruteiern durch Begasung mit Formaldehyd – eine Übersicht

Microbial contamination of hatching eggs is a main concern of poultry producers as it causes poor hatchability and chick performance. It is evident that high standards of hygiene must be practised in hatcheries in order to minimise the soiling of eggs but, further disinfection of eggs is also necessary to limit bacterial numbers. Methods used include the application of disinfectants by wiping, ...

Disinfection By-products: A Question of Balance

By all accounts, disinfection of drinking water is one of the major public health triumphs of the 20th century. No human endeavor, however, is without risk; more than 30 years ago it was determined that chlori­ nation of water resulted in formation of disinfection by­products (DBPs). Several of these, such as the trihalomethanes (THMs) and haloacetic acids (HAAs), were subsequently observed to ...

Mutagenic activity of disinfection by-products.

Data on raw water quality, disinfection treatment practices, and the resulting mutagenic properties of the treated water were compiled from pilot- and full-scale treatment experiments to evaluate that parameter which might produce variability in the results of a mutagenic study. Analysis of the data and comparison of treatment practices indicated that the measured mutagenic activity is strongly...

Reproductive toxicology of disinfection by-products.

The chronic exposure of large segments of the population to disinfected drinking water has necessitated an evaluation of the health effects of the by-products of the chlorination process. This paper reviews the available information concerning the reproductive consequences associated with exposure to disinfection by-products. Four groups of compounds are discussed: the trihalomethanes, in parti...
