UNLABELLED BACKGROUND To look at possible long-term risks from anabolic steroids and other xenobiotics in beef, we examined men's semen quality in relation to their mother's self-reported beef consumption during pregnancy. METHODS The study was carried out in five US cities between 1999 and 2005. We used regression analyses to examine semen parameters in 387 partners of pregnant women in rela...

BACKGROUND: To look at possible long-term risks from anabolic steroids and other xenobiotics in beef, we examined mens’ semen quality in relation to their mother’s self-reported beef consumption during pregnancy.

Cindy Tian et al. report that meat and milk from cloned bulls and cows, respectively, appear to meet regulatory standards. The researchers cloned a Japanese Black beef bull and Holstein dairy cow, using somatic cell nuclear transfer, and compared the meat and milk from two beef clones and four dairy clones to that of geneticand breed-matched control animals bred through conventional reproductio...

The effect of moderate pressure at subzero temperature on natural microflora of minced cod, salmon, pork and beef meat was studied. Pressure of 193 MPa at –20 °C caused the reduction of total bacterial count in pork and beef meat by 1.1 and 0.6 log cycles, respectively, and by about 1.5 log cycles in fish meat. Under these conditions the psychrophilic and psychrotrophic bacteria were below the ...

1. An extracellular, proteolytic enzyme has been observed in more than 30 strains of beta type, aerobic and facultative hemolytic streptococci. 2. The enzyme is readily demonstrable in sterile filtrates of cooked meat cultures. 3. No gas or foul odor is produced. 4. It is partially inactivated by exposure to about 60 degrees C. for 45 minutes or longer. 5. The enzyme manifests itself in cooked ...

Retail stores often offer discounts on purchases of large amounts of meat. Some of the meat is prepared the same day, and some is stored for later use. This study evaluates the effect of retail packaging, freezing and thawing on the quality of beef patties. Loosely ground beef was retail-packed in: (1) highly permeable wrap, and (2) high oxygen MAP. The meat was subsequently refrigerated at 4°C...

Campylobacter jejuni and C. coli are the main causes of gastrointestinal diseases in humans even in industrialized countries affecting public health. The aim of the current study was to evaluate the occurrence and antibiotic resistance of C. jejuni and C. coli in chicken meat, beef, mutton and water buffalo meat slaughtered in Ahvaz city, Iran. A total of 380...

The effect of irradiation and packaging conditions on the content of cholesterol oxidation products (COPs) and lipid oxidation in cooked turkey, beef, and pork during storage was studied. Ground turkey leg, beef, and pork were cooked, packaged either in oxygen-permeable or oxygen-impermeable bags, and irradiated at 0 or 4.5 kGy. Lipid oxidation and COPs were determined after 0 and 7 days of sto...

Pork is the most widely eaten meat in the world and recent evidence shows that diets high in pork protein, with and without energy restriction, may have favourable effects on body composition. However, it is unclear whether these effects on body composition are specific to pork or whether consumption of other high protein meat diets may have the same benefit. Therefore we aimed to compare regul...
