The invention provides a determining method for polluted water bed mud environmental protection dredging depth, comprising analyzing and evaluating the releasing risk and ecological hazard risk of the pollutant at different layer side of the mud based on the vertical distribution of the pollutant in the bed mud by researching the relation of the releasing of bed mud pollutant nitrogen, phosphor or the like and the corresponding pollutant content and the ecological hazard evaluation corresponding with the content of the bed mud pollutant containing heavy metal; and determining the bed mud dredging depth based on the divided corresponding risk grade. After dredging, the anticipated release rate of the key pollutant such as nitrogen, phosphor at the new surface layer of bed mud-hydrosphere achieves or exceeds a release intensity threshold and the latent ecological hazard index of the heavy metal at the new surface layer of bed mud achieves or exceeds a hazard threshold, therefore the basis of the dredging depth is determined.

A method of controlling microbial contamination of poultry carcasses in the processing of poultry as food products is described. The method comprises contacting the carcasses with an aqueous medium containing an effective microbial inhibiting amount of active bromine resulting from the addition to the medium of (i) at least one 1,3-dibromo-5,5-dialkylhydantoinin which one of the alkyl groups is a methyl group and the other alkyl group contains in the range of 1 to about 4 carbon atoms or (ii) a solution thereof, or (iii) both of (i) and (ii). Such contacting inhibits contamination of the carcasses by microorganisms, even at least some bacteria that are resistant to antibiotics or antibacterials. Also described are improvements in a poultry chill tank containing an aqueous medium and a plurality of poultry carcasses in contact with the medium. Such improvements result from the presence in the medium of an effective microbial inhibiting amount of active bromine in the medium, which amount results from the addition to water before it enters the tank or while it is in the tank, or both, of (i) at least one of the above 1,3-dibromo-5,5-dialkylhydantoins, and / or a solution thereof.
