Abstract: 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-dialkylhydantoin in 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.

The mixture is comprised of (i) a poly(bromophenyl)alkane having in the molecule in the range of 13 to 60 carbon atoms and in the range of two to four aryl groups and (ii) a poly(bromophenyl)bromoalkane having in the molecule in the range of 13 to 60 carbon atoms and in the range of two to four aryl groups, said poly(bromophenyl)bromoalkane being in an amount which is greater than 25 wt %, based on the total weight of the additive mixture. A facile process for making the poly(bromophenyl)bromoalkane is also described.
Abstract: This invention relates to a novel process which comprises feeding a mixture formed from diphenylethane and bromine to a stirrable reaction mass comprised of bromine and a bromination catalyst to yield a decabromodiphenylethane wet cake which can be most economically treated to provide a high quality decabromodiphenylethane product.

Abstract: Described is a process of producing a concentrated liquid biocide formulation. Mixed together are (a) bromine chloride or bromine and (b) an aqueous solution of alkali metal salt of sulfamic acid having a pH of at least about 7, in amounts such that (i) the active bromine content of the solution is at least about 100,000 ppm (wt/wt), and (ii) the atom ratio of nitrogen to active bromine from (a) and (b) is greater than 1 when bromine is used and is greater than 0.93 when bromine chloride is used. Use of bromine chloride as the source of the active bromine in the process is preferred because in the resulting aqueous compositions, all of the bromine of the bromine chloride is made available as active bromine in solution. In other words, the chlorine of the bromine chloride is converted in the process to dissolved alkali metal chloride salt, thereby liberating all of the bromine in the biocidal composition as active bromine capable of providing biocidal activity.
