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...

Abstract Polycyclic aromatic hydrocarbons (PAHs) are classified as persistent and carcinogenic organic pollutants. PAHs contamination has been reported in water. Many of relevant regulatory bodies such as EU and EPA have regulated the limit levels for PAHs in drinking water. In this study, 13 priority polycyclic aromatic hydrocarbons (PAHs) were determined in tap water samples of Tehran and wat...

Background: 99mTc is a widely used radioisotope in nuclear medicine centers which is obtained by elution from Mo-99/Tc-99m generators. Usually the generators are either supplied by the Iran Atomic Energy Agency or by private companies from foreign countries. In this study we have measured 99Mo contamination in 99mTc elute from different generators in a period of one year. Materials and...

This paper summarizes parenteral drug contamination case studies presented at industry conferences and a Food and Drug Administration advisory committee meeting in the period of 2000-2004. CGMP deficiencies associated with each contamination event are discussed. The key role of a well-functioning quality system in contamination prevention is emphasized.

Per- and poly-fluoroalkyl substances (PFASs) are persistent bioaccumulative compounds with adverse impacts on the environment human health. Diet is one of main sources exposure to PFASs. Recently, EFSA established a tolerable weekly intake (TWI) limit (4.4 ng/kg b.w.) for mixture four major Eggs egg products can contribute this intake, their contamination possibly dependent husbandry system. Mo...

The presence of cytotoxic agents in the urine of operators and in their environment has been demonstrated. The pharmacokinetics of the urinary elimination of cyclophosphamide suggests that these drugs are absorbed cutaneously during handling. In the framework of a more general study on the contamination of hospital environment, the present study addresses the possible presence of cytotoxic agen...

This study deals with a PCB, PCDD and PCDF contamination in Brescia, a city in the North-West of Italy, affecting an area with about 11000 inhabitants. The area is close to an industrial plant that produced, in total, some 31,000 ton of PCB. A relevant part of the polluted area is agricultural soil, where cattle were fed with polluted forage and farmers were consuming their own products, so tha...

BACKGROUND Many patients suffer from recurrent Staphylococcus aureus infections, but there are few data examining recurrence predictors. METHODS We followed adults and children after treatment for S. aureus skin infections and their household contacts in Los Angeles and Chicago. We surveyed subjects for S. aureus body colonization, household fomite contamination, and behavioral and clinical f...
