the objective of this study was to evaluate kinetics and the residual decline of tylosin in milk and plasma of lactating najdi ewes following single intramuscular injection of tylosin at the dose of 10 mg/kg. blood and milk samples were collected from the ewes before and at different time intervals after treatment. tylosin concentrations were determined by microbiological agar plate assay using...

background: the presence of aflatoxin m1 (afm1) andantibiotic residues in milk and milk products is a public healthconcern. milk and milk powder have the potential forintroducing afm1 and antibiotic into human diet. in recentyears, milk powder has been used on a large scale in dairyfactories. consequently, antibiotic residues and aflatoxincontamination control in these products has gained impor...

an experiment was conducted to evaluate the effects of some technological processes on the residual levels of imidacloprid in strawberry fruits and products. according to their half-life (t1/2) values, strawberry fruits can be safely harvested for human consumption 7.4 days after spraying. the removal ratio of imidacloprid residue in strawberries was in the range of 9.9–30.55% by washing with t...

Surveillance at the slaughterhouse level for animal health and food safety purposes encompasses examination for the presence of pathology, pathogens, drug residues, chemical contaminants and antimicrobial resistance. Government, industry and academia are the primary proponents of such surveillance. A variety of policies and policy instruments from voluntary to legislative may be applied to prom...

The aim of our study was to investigate the amount of 110 pesticide residues in cereals and foodstuff from Poland as a part of official control. A total of 89 samples were collected in 2009-10. In 84.2% of the samples no residues were found: 15.8% of samples contained pesticide residues below the maximum residue limit. Pirimiphos-methyl was the most frequently found pesticide. The results show ...

Eel culture and export to the Japanese market is an important industry in Taiwan; however, the average amount produced by each farm is small. Eels from different farms might be mixed before export, making it difficult to determine which farm is responsible for eels containing drug residues. Therefore, the Taiwanese government uses a two-stage procedure of inspection and accreditation for valida...

The sources of quantitative and qualitative uncertainties of the exposure of a consumer to a pesticide residue are identified. The contribution of quantifiable uncertainties of input parameters of deterministic model to the combined uncertainty of the estimated exposure is shown with detailed calculation using the pesticide residue content of food consumed during two days. The daily intakes of ...
