“…The crude protein, ash, crude fat, crude fiber, calcium, potassium, magnesium and phosphorus contents of BL after fermentation were lower (P<0.05) than prior t o fermentation (Table l), because some components were denatured by the heat and the acidic condition of fermentation and were decomposed by anaerobic microorganisms (Driehuis et al, 2000;Davis et al, 2002). Meanwhile, the contents of normal BL and fermented BL after pelleting were not affected by the heat and pressure from the pelleting process (P>0.05), probably because the heat (-9OC) and pressure from the pelleting process occurred over a short period (-5-10 sec) (Suppadit, 2000).…”

“…If improperly managed, BL can pollute the environment, principally by contaminating surface and ground water (Suppadit, 2002). I n addition, processing may improve the handling characteristics of BL by decreasing smell and may increase the nutritive value of BL (Davis et al, 2002). To overcome these problems, the fermentation and pelleting of the BL is proposed, with the objectives to determine the effect of these processes on the nutritive values of BL before and after the modification on the proximate composition and to evaluate the effectiveness of fermentation a n d pelleting i n the elimination of the potential risks.…”

“…Fresh beef becomes contaminated with spoilage as well as pathogens during the slaughter process when faecal materials come into contact with the carcass producing surface contamination on the carcass, which may be transported into the interior of the meat tissues [23] . These microorganisms have serious effect on meat safety issues resulting in immediate consumer health problems.…”

This study was aiming to present some approaches by which the shelf life of fresh beef cuts was extended. These approaches were based on using organic acids. Therefore the work was started with highlighting the deterioration of some quality attributes due to spoilage and pathogenic microorganisms. These attributes included colour, flavour and lipid oxidation changes. In a given holding temperature, the deterioration are controlled by three major factors, they are pH, water activity and microbial growth. The four organic acids approaches (citric, lactic, acetic and tartaric) were presented as fresh beef shelf life extenders due to their abilities to decrease the pH and antimicrobial effects. The pros and cons of these approaches as well as the latest published researches were stressed at the end of this review. This information helps the researchers and gives them the motivation to develop new superior approach.

“…Assuming 1 kg of litter per broiler (4) put to market, approximately 1.6 billion kg of litter per year must be managed in the United States. Poultry litter is commonly utilized as fertilizer or as cattle feed (7). Properly managed, poultry litter can provide essential nutrients for crop production, such as N, P, and K (12,26).…”

The impact of fecal contamination from human and agricultural animal waste on water quality is a major public health concern. Identification of the dominant source(s) of fecal pollution in a watershed is necessary for assessing the safety of recreational water and protecting water resources. A field study was conducted using quantitative PCR (qPCR) for the 16S rRNA gene of Brevibacterium sp. LA35 to track feces-contaminated poultry litter in environmental samples. Based on sensitivity and specificity characteristics of the qPCR method, the Bayesian conditional probability that detection of the LA35 marker gene in a water sample represented a true-positive result was 93%. The marker's covariance with fecal indicator bacteria (FIB) and metals associated with poultry litter was also assessed in litter, runoff, surface water, and groundwater samples. LA35 was detected in water and soil samples collected throughout the watershed, and its concentration covaried with concentrations of Escherichia coli, enterococci, As, Cu, P, and Zn. Significantly greater concentrations of FIB, As, Cu, P, and Zn were observed in edge-of-field runoff samples in which LA35 was detected, compared to samples in which it was not detected. Furthermore, As, Cu, P, and Zn concentrations covaried in environmental samples in which LA35 was detected and typically did not in samples in which the marker gene was not detected. The covariance of the poultry-specific LA35 marker gene with these known contaminants from poultry feces provides further evidence that it is a useful tool for assessing the impact of poultry-derived fecal pollution in environmental waters.
