The aim of this study was to evaluate aflatoxin M1 (AFM1) contamination in pasteurized milk samples in Mashhad, Iran. One hundred and ten milk samples from different supermarkets were collected during three months in spring and investigated by Enzyme Linked Immuno Sorbent Assay (ELISA). AFM1 was found in 100% of the milk samples. About 5.4% of the samples c...

We investigate the performance of robust estimates of multivariate location under nonstandard data contamination models such as componentwise outliers (i.e., contamination in each variable is independent from the other variables). This model brings up a possible new source of statistical error that we call “propagation of outliers.” This source of error is unusual in the sense that it is genera...

INTRODUCTION Contamination of pharmaceutical preparations by micro-organisms continues to be a matter of concern to the pharmacists. From the beginning it has been an official requirement that parenteral preparations shall be sterile. More recently a number of serious infections in the eye in Britain and elsewhere have resulted in the further requirement that all preparations used in the eye sh...

BACKGROUND Aflatoxin, a potent fungal toxin, contaminates 25% of crops worldwide. Since 2004, 477 aflatoxin poisonings associated with eating contaminated maize have been documented in Eastern Kenya, with a case-fatality rate of 40%. OBJECTIVE We characterized maize aflatoxin contamination during the high-risk season (April-June) after the major harvests in 2005, 2006 (aflatoxicosis outbreak ...

Washing procedures applied to fresh produce have the potential to reduce contamination from the surface of the product. However, the wash water may also serve as a source of contamination or has great potential to result in cross-contamination. The objective of this study was to evaluate process handling cross-contamination potential and pathogen removal of initially low numbers of attached cel...

There are many factors that affect the groundwater contamination in the highway environment. This paper reports a 2-dimensional numerical simulation of the movement of contamination with water into the sub-grade and water table beneath a road to determine the major factors affecting transport of contaminants. The modelling parameters were assembled from various literature sources and 8 scenario...

PURPOSE No occupational exposure limit exists for antineoplastic drugs. The main objective of this study was to describe environmental contamination with cyclophosphamide, ifosfamide and methotrexate in pharmacy and patient care areas of Canadian hospitals in 2012. The secondary objective was to compare the 2012 environmental monitoring results with the 2008-2010 results. METHODS Six standard...

background and purpose :aflatoxin m1, in milk and dairy products, is classified by the international agency for research on cancer as human carcinogens (class 2b). the aim of this study was to evaluate aflatoxin m1 contamination level in dairy products from iranshahr city, iran, using elisa technique. materials and methods: in our study, 87 samples of milk, white cheese, yoghurt, and butter wer...

Applying basic physical principles to recent observational results, we derive upper and lower limits on microwave anisotropy from point sources over the range of frequencies 10-1000 GHz. We examine the level of noise in the observations as a possible indication of source confusion at subarcminute scales. We also derive an upper limit on microwave anisotropy caused by the sources responsible for...
