This study tested 3 food enrichment items mentioned in a laboratory primate newsletter with 6 adult Eulemur macaco and 3 adult Lemur catta to examine whether the items would affect the behavior of the lemurs. The results suggest that Food Enrichment Item 3 (a wire box filled with whole grapes, apples, or both hidden in straw hung from a branch within the enclosure) caused a significant decrease...

Background: Salmonella is one of the most common food-borne pathogens that can cause illness. In this study, the sensitivity and the specificity of Aptamer-Magnetic bead Separation-Polymerase Chain Reaction (AMS-PCR) method were determined for Salmonella spp. detection. Methods: Different concentrations of Salmonella enterica were mixed with streptavidin-magnetic beads coated with biotinylated...

Listeria monocytogenes, a foodborne pathogen that can cause listeriosis through the consumption of food contaminated with this pathogen. The ability of L. monocytogenes to survive in extreme conditions and cause food contaminations have become a major concern. Hence, routine microbiological food testing is necessary to prevent food contamination and outbreaks of foodborne illness. This review p...

Four food-based enrichment devices were used to test the effects of single-use and group-use enrichment devices on stereotypy, intragroup aggression, and affiliation in a compatible group of 5 squirrel monkeys (Saimiri sciureus). All enrichment devices were found to reduce overall stereotypic behavior from baseline levels (without enrichment). The occurrence of stereotypic behavior differed bet...

Introduction (Steinkraus 1995, 1996a, 1997) Fermented foods are food substrates that are invaded or overgrown by edible microorganisms whose enzymes, particularly amylases, proteases, lipases hydrolyze the polysaccharides, proteins and lipids to nontoxic products with flavors, aromas and textures pleasant and attractive to the human consumer. If the products of enzyme activities have unpleasant...

Coal mining and related industry can increase heavy metals (HMs) concentrations in soil, atmosphere and wheat, thereby posing metal-associated human health risk via food ingestion.  In this study, 58 samples of soil, wheat, and dust were collected from Xuzhou coal mine eastern China, six kinds of HMs Pb, Cd, Cu, Zn, As and Cr were studied for their spatial distribution in wheat, enrichment in d...
