“…Salmonella can survive in feed for prolonged periods of time and contaminate farm animals. In several studies, Salmonella could readily be isolated from several samples that had been stored at room temperature for up to 3 years (D'Aoust, 1977;D'Aoust & Sewell, 1986;Ray, Jezeski, & Busta, 1971;Rayman, D'Aoust, Aris, Maishment, & Wasik, 1979). In another study, broth culture of S. Typhimurium (5.6e9.8 ✕ 10 8 CFU/ml) was added to 70 g of pelleted poultry feed and the samples were stored at 11, 25, and 38 C, with a relative humidity of 68, 51, and 27%, respectively.…”
