Survival of E. coli O157:H7 on beef treated with 2% or 5% lactic acid The aim of this American study was to investigate the effects of lactic acid sprays on acid-tolerant E. coli O157:H7 and E. coli on beef surfaces, slices of beef with cut muscle, fat and membrane surfaces. The surfaces were inoculated with a five strain cocktail of acid-adapted E. coli O157:H7, or with a non-acid-adapted stra...

A study was conducted to analyze resource allocation for public meat research in the United States and characterize the portfolio of meat research investments. Trends in the amount of public resources provided for meat research (beef, pork, lamb, and poultry) were analyzed for fiscal years 1980, 1985, 1990, 1995, and 1997. An in-depth analysis was conducted for data from fiscal year 1998 to cha...

Genetic modification offers alternative strategies to traditional animal breeding. However, the food safety of genetically modified (GM) animals has attracted increasing levels of concern. In this study, we produced GM sheep overexpressing TLR4, and the transgene-positive offsprings (F1) were confirmed using the polymerase chain reaction (PCR) and Southern blot. The expression of TLR4 was 2.5-f...

Blue crab processors need packaging options for fresh and pasteurized crab meat that reduce processing and packaging costs, improve quality, safety, and shelf life, and accommodate smaller portion sizes. Traditional fresh and pasteurized crab meat containers are 16 oz polyethylene cups and 16 oz steel cans, respectively. Processors have been presented with a number of new commercial options for...

Fresh and packaged food safety, especially of meat products has become a major issue because of microbial contamination. In the present study, an attempt has been made to isolate bacteria from fresh and packaged meat products from various sources and locations. The isolated bacterial samples were identified by Phenotypic, biochemical and molecular characterization. The veracity of the contamina...
