This study uses retail purchase data reported by the Nielsen Homescan panel to examine the development of selected U.S. organic food sectors since the implementation of the National Organic Standards. Results show that organic market shares within the fresh fruit and vegetable sectors grew slightly in 2003–2006. Apples, bananas, carrots, and tomatoes prove to have the highest share of organic s...

BACKGROUND Biomonitoring data of persistent organic pollutants (POPs) in breast milk are increasingly collected and available for quantitative analysis of levels and time trends. A common approach is to apply log-linear regression to calculate doubling and halving times of the POP concentrations based on the temporal trend observed in breast milk. However, there are different, sometimes conflic...

Milk from ruminant animals has been an important component of the human diet for thousands of years. Ruminants have the unique ability to take organic material that is indigestible to humans and convert it into milk, a food with high nutritional value. Ancient civilizations learnt to exploit this potential through the domestication of various species of ruminant including the cow, sheep, goat, ...

As one of the three natural isotopes of hydrogen, tritium is ubiquitous and may potentially be present in any water or organic molecule that constitutes a biological matrix. Milk is one of the most frequently monitored foodstuffs in the vicinity of chronic release of radionuclides, as it is a very common food product and also because it integrates deposition on large areas of grass or crops at ...

Polycyclic aromatic hydrocarbons (PAHs) are lipophilic organic pollutants occurring widely in the terrestrial environment. To study the transfer of PAHs in the food chain, pigs have been fed with milk spiked either with [(14)C]phenanthrene or with [(14)C]benzo[a]pyrene. The analysis of blood radioactivity showed that both PAHs were absorbed with a maximum concentration at 5--6 h after milk inge...

Performance records (birth weight and actual milk yield) on 206 Swedish Red cattle maintained at private organic diary cattle enterprise in Kelkit district of Gümüşhane province, in Turkey, were analyzed through regression tree method to determine the effects of some factors affecting birth weight and actual milk yield. The birth weight of calves averaged as 41.034±4.218 kg. Out of total calves...

The rapid detection of Listeria monocytogenes contamination in food is essential to prevent food-borne illness in humans. The aim of this study was to differentiate non-contaminated milk from milk contaminated with L. monocytogenes using enzyme substrates coupled with the analysis of volatile organic compounds (VOCs). The method is based on the activity of β-glucosidase and hippuricase enzymes ...

recently organic agriculture as a most popular alternative production system has increasingly been considered by scientists, people and policymakers and governments in the world, and many research programs are directed to this sustainable production system. in organic agriculture it is hardly recommended to integrate plant with animal husbandry in agroecosystem. various animal products such as ...

the present study was conducted on efficiency of utilization of dietary energy for milk production in lactating crossbred cattle. 18 lactating crossbred cattle of early to mid-lactation, approximate body weight (375.39±23.43 kg), milk yield, parity and stage of lactation were divided into three groups of six animals each and were fed 0, 50 and 100% diammonium phosphate (dap) in the mineral mixt...
