A study was conducted on raw cow's milk to measure the residues of 15 organophosphorus pesticides used as dairy cattle ectoparasiticides or as insecticides in crops used for animal feed. For this purpose a previously devised method was improved and validated. The samples were collected directly from tank trucks during delivery of 3,974 tonnes of raw milk at nine Italian dairy plants. Approximately 4.4% of the 298 samples analyzed contained residues only in traces. The main pollutant was chlorpyriphos.

Electrolyzed oxidizing water (EOW) has potential application as a residue free sanitizing agent for food of animal origin. Meat and poultry were contaminated with microorganism, pathogens or not, and different types of electrolyzed oxidizing water treatement were investigated to evaluate the activity of each of these method. In detail, this study is aiming at evaluating the effectiveness of EOW in reducing microbial count, including total bacterial count, Salmonella Typhimurium, Staphylococcus aureus, Listeria monocytogenes and Escherichia coli on meat and poultry. EOW has a very strong disinfectant activity which, along with its easy and safe use, makes a good alternative to many other more widely used disinfectants
