1. Dietary risk assessment of fluoride, lead, chromium, and cadmium through consumption of Tieguanyin tea and white tea
Abstract Food and beverage consumption is the most possible route of human exposure to undesirable elements. Tieguanyin tea and white tea are widely-consumed beverage, which may be contaminated by fluoride (F), lead (Pb), chromium (Cr), and cadmium (Cd). For this study, the contamination levels and dietary exposure risks of these elements were studied from 7

2. First molecular detection of Coxiella burnetii in Brazilian artisanal cheese: a neglected food safety hazard in ready-to-eat raw-milk product
ABSTRACT Background: Global publications on Q fever have increased after the 2007 epidemic in the Netherlands. However, the epidemiology of Q fever/coxiellosis in Brazil is still poorly understood. Accordingly, there have been few studies investigating the presence of Coxiella burnetii in dairy products around the world, especially in Brazil, where consumpt

4. Development of multiplex loop-mediated isothermal amplification for three foodborne pathogens
Abstract Staphylococcus aureus, Salmonella, and Shigella are three major foodborne pathogenic microorganisms that cause global public health problems. We developed a multiplex loop-mediated isothermal amplification (mLAMP) assay for simultaneous detection of S. aureus nuc, Salmonella fimY, and Shigella ipaH in fresh fruit juice using three sets of primers.

5. Fragment detection of Coleopteran and Triatomine insects in experimentally contaminated acai pulp and sugarcane juice
Abstract INTRODUCTION: Oral transmission of acute Chagas disease is an emerging public health concern. This study aimed to detect insect fragments in experimentally contaminated food, by comparing triatomines with other insects. METHODS Food samples were experimentally contaminated with insects, processed to recover their fragments by light filth, and an

8. Detecção de Campylobacter jejuni em produtos de frango utilizando separação imunomagnética
RESUMO Campylobacter jejuni é o principal causador de gastroenterite bacteriana aguda, e a carne de frango tem se mostrado uma importante fonte de transmissão. Este microrganismo é de difícil isolamento e os métodos convencionais muitas vezes não são eficientes, podendo levar a resultados errôneos. O objetivo deste trabalho foi desenvolver e testar a

10. Risk assessment of the occurrence of aflatoxin and fungi in peanuts and cashew nuts
In the present study, the occurrence of fungi and aflatoxins (AFs) in peanut and cashew nut samples was investigated. Mycological analysis revealed the presence of fungi in 58.8% of samples, and assessment of AFs by chromatographic methods revealed that 52.9% were contaminated by AFs. AFB1 was the principal component in all AF-contaminated samples, with a me

11. An evaluation of immunomagnetic separation-real-time PCR (IMS-RTiPCR) combined assay for rapid and specific detection of Escherichia coli O157:H7 in raw milk and ground beef
Abstract The aim of this study is to optimize a rapid and specific method for detection of E. coli O157:H7 (EHEC) from food samples with high background flora using an immunomagnetic separation-real-time polymerase chain reaction assay (IMS-RTiPCR). For this, EHEC cells were recovered from raw milk and ground meat samples that were artificially contaminated
