High intake of meat, particularly red and processed meat, has been associated with an increased risk of a number of common cancers such as breast, colorectum, and prostate in many epidemiological studies. Heterocyclic amines (HCAs) are a group of mutagenic compounds found in cooked meats, particularly well-done meats. HCAs are some of most potent mutagens detected using the Ames/salmonella test...

Hepatitis A virus (HAV) and Norwalk-like virus (NLV) were detected by reverse transcription-PCR in clams imported into the United States from China. An epidemiological investigation showed that these clams were associated with five cases of Norwalk-like gastroenteritis in New York State in August 2000 (Food and Drug Administration Import Alert 16-50). They were labeled "cooked" but appeared raw...

Beef and lamb, are a food category with positive and negative nutritional attributes. Rumi‐ nant meats are major sources for many bioactive compounds including iron, zinc and B vita‐ mins. However they are associated with nutrients and nutritional profiles that are considered negative including high levels of saturated fatty acids (SFA) and cholesterol. It is well know that the low PUFA/SFA and...

The custom of displaying Chinese-style barbecued meats at room temperature has been a controversial food safety issue in North America. This article is intended to facilitate development of a risk-based food safety policy for this unique food by providing a brief overview of the recent study findings and Canadian disease surveillance data. Despite the lack of temperature control after cooking, ...

quality and safety. Extended shelf life refrigerated foods are foods that have received minimal processing or precooking and have an enhanced but limited shelf life; refrigeration is a key preservation measure. These foods include conventional products, such as luncheon meats and cured meats, as well as a new generation of partially processed refrigerated foods (NFPA, 1988) such as meat, seafoo...

A simple and rapid multi-residue method was developed for the determination of 28 kinds of veterinary drugs and feed additives (drugs) in muscle of cattle, pig and chicken. The drugs were extracted with acetonitrile-water (95:5) in a homogenizer and ultrasonic generator. The extracted solution was poured into an alumina column and the drugs were eluted with acetonitrile-water (90:10). The eluat...

The growing popularity of food products marketed in the United States as "natural" and "organic" has resulted in a proliferation of marketing efforts to meet consumer demands for these foods. Because natural and organic foods are not permitted to use chemical preservatives, the traditional curing agents used for cured meats, nitrate and/or nitrite, cannot be added to natural and organic process...

Epidemiologic studies have implicated exposure to tobacco smoke and high intakes of cooked, broiled, or well-done meats in the increased risk of colorectal cancers (1-4). Microsomal epoxide hydrolase (mEH) is a phase II biotransformation enzyme which detoxifies epoxides, including carcinogens such as polycyclic aromatic hydrocarbons found in cigarette smoke and cooked meats (5). A tyrosine to h...

Food falsification has direct impact on public health, religious faith, fair-trades and wildlife. For the first time, here we described a multiplex polymerase chain reaction assay for the accurate identification of five meat species forbidden in Islamic foods in a single assay platform. Five pairs of species-specific primers were designed targeting mitochondrial ND5, ATPase 6, and cytochrome b ...
