Abstract Mycotoxins are secondary metabolites produced by fungal species that mainly belong to Aspergillus, Fusarium, Penicillium and Alternaria, which can grow in a variety of crops including cereals, oilseeds and fruits. Consequently, their prevalence in foods and by-products not only affects human and...
Abstract We studied and compared the prevalence of Campylobacter jejuni and Campylobacter coli in chicken carcasses from conventional and kosher broiler abattoirs and retail stores. The prevalence of thermotolerant Campylobacter-positive carcasses was 94.0 (kosher) and 32.0% (conventional) (p< 0.0001)...

In Brazil, quantification of caseinomacropeptide (CMP) index, using High Performance Liquid Chromatography (HPLC), ...
Norovirus (NoV) is the main cause of gastroenteritis outbreaks worldwide. Although NoV spreads mainly from person to person, it is estimated that a large proportion of NoV outbreaks are caused by foodborne transmission. Bivalve mollusks are one of the most important foods involved in NoV transmission to ...
This paper investigated the occurrence of Staphylococcus aureus and the detection of enterotoxin-encoding genes of these strains in milk collected from 30 Murrah buffaloes used to produce dairy products in Brazil. A total of 68 strains of Staphylococcus aureus were found as identified by conventional lab...
ABSTRACT The presence of mycotoxins or related fungi in animal feed is a major problem for animal and human health.
