Direct Application of a New Hypochlorite Sanitizer for Reducing Bacterial Contamination on Foods.

The efficacy of the buffered sodium hypochlorite solution, Bionox, in controlling bacterial contamination was evaluated on fresh-cut poultry (chicken, light and dark meat), fish fillets, fruit, and vegetables. Food products were immersed in a nutrient broth suspension of Salmonella enteritidis (ATCC #13067) for 30 s and allowed to drip/air dry for 10 s prior to exposure to the sanitizing agent. Food products were then each vigorously washed with 100 ml of buffered peptone which was plated in serial dilution on XLD-N agar and incubated at 37°C for 24 h.

Reduction of Mutagenic Potentials in Milk: Effects of Ammonia Treatment on Aflatoxin-Contaminated Cottonseed.

Milks obtained from cows fed rations containing aflatoxin-contaminated cottonseed, ammonia-treated aflatoxin-contaminated cottonseed, and uncontaminated cottonseed were tested for mutagenic potential using the Salmonella /mammalian microsome mutagenicity assay using Salmonella typhimurium strains TA98 and TA100. Standard assay protocol was used with S-9 liver homogenate added. Samples including whole milk, nonfat dry milk powder, cream, and reconstituted whole milk were applied directly to the plates in triplicate.
