Microbiological quality and safety of zoo food.

摘要: Two types of commercial products for feeding zoo animals (a frozen meat product, referred to as food, and a dry food) were microbiologically examined spoilage organisms (aerobic, psychrotrophic, coliform, Escherichia coli, mold, yeasts) pathogens (Salmonella spp., Listeria monocytogenes, Campylobacter jejuni). Levels microorganisms in ground food compared with those beef turkey meat. The level microbial contaminants was found be similar that higher than Sixty percent the samples Salmonella positive, all L. monocytogenes positive. Dry documented have levels lower meat; pathogen less 1/25 g food. Defrosting at 10, 25, 37 degrees C 24 h showed 10 is best temperature defrosting loaves (length, 9 in. [22.8 cm]; radius, 2 [5.1 cm]) without affecting microbiological quality or safety product.
