Aims: To assess norovirus (NoV) contamination in aquatic ecosystems in the city of Florianópolis, in Southern Brazil, in order to provide epidemiological data that can support actions for environmental contamination control.
Methods and Results: An adsorption‐elution method, followed by ultrafiltration, was performed to concentrate the viruses. NoV were detected using semi‐nested PCR...
Aims: This study aimed to compare the efficacy of different disinfection methods in eliminating Salmonella contamination from turkey houses.
Methods and results: Fifty depopulated turkey houses which had all housed Salmonella‐positive flocks were visited after cleaning and disinfection. A minimum of 45 swab samples from different surfaces were taken per house and analysed for the...
Aims: To develop simple and rapid PCR‐fingerprinting methods for Vibrio cholerae O1 (El Tor and classical biotypes) and O139 serogroup strains which cause major cholera epidemics, on the basis of the diversity of superintegron (SI) carried by these strains.
Methods and Results: PCR‐restriction fragment length polymorphism (PCR‐RFLP) assay was developed targeting region between...
The recent report of elevated acrylamide levels in heat processing foods evoked an international health alarm. Acrylamide, an acknowledged potential genetic and reproductive toxin with mutagenic and carcinogenic properties in experimental mammalians, has been found in various heat processing foods. ...

The Failure Mode and Effect Analysis (FMEA) model has been applied for the risk assessment of corn curl manufacturing. A tentative approach of FMEA application to the snacks industry was attempted in an effort to exclude the presence of GMOs in the final product. This is of crucial importance both ... (Publication: )
Mycotoxins are fungal secondary metabolites that have been associated with severe toxic effects to vertebrates produced by many important phytopathogenic and food spoilage fungi including Aspergillus, Penicillium, Fusarium, and Alternaria species. The contamination of foods and animal feeds with ... (Publication: )
Shigella, the causative agent of shigellosis or "bacillary dysentery," has been increasingly involved in foodborne outbreaks. According to the Centers for Disease Control and Prevention's Emerging Infections Program, Foodborne Diseases Active Surveillance Network (FoodNet), Shigella was the third ... (Publication: )
The comparison of the various sources of food contamination with organic chemicals suggests that in the public, but also among experts, the perception of risk is often distorted. Firstly, neither pesticides nor environmental pollutants contribute the most; the amount of material migrating from food ... (Publication: )
Ochratoxin A (OTA) are synthesized mainly by different species of Aspergillus and Penicillium being its human toxicological effects reflected in different countries due to the consumption of different foods and beverages such as red, white, rose, and special wines. This review presents an overview ... (Publication: )
An article is presented describing the background information on the use of ozone, bacteriocins and irradiation for destroying pathogens in food products. Their effectiveness on some pathogens of importance in food processing systems and issues of concern are highlighted. It could be concluded that ... (Publication: )
The production of flour and semolina and their ensuing products, such as bread, cake, spaghetti, noodles, and cornflakes, is of major importance, because these products constitute some of the main ingredients of the human diet. The Hazard Analysis Critical Control Point (HACCP) system aims at ... (Publication: )
