Ozone gas (O3) is used as an oxidizing agent and can be applied as a sanitizer to control microorganisms and degrade toxic compounds, such as pesticides and mycotoxins, in food industries. Some studies investigated the use of O3 as an agent to reduce pathogenic bacteria such as Salmonella enteritidis. The action of O3 on the eggshell cuticle and st...

Decontamination methods of egg change according to the different countries. However, this practice is extremly important, because there may be contamination by a wide range of micoorganisms. In free-range raising systems, in addition to being exposed to the pathogenic microorganisms, hens may be also exposed to a different kinds of fungy, both fiel...

During the food production process, qualitative losses are caused by biological contaminants (fungi, mycotoxins, and insects) and chemical contaminants (pesticide residues), widely found in grain storage. Several species of fungi, when they find ideal conditions for their development in the silos, cause damage to the grains (clod formation, grain h...

Poultry litter has been utilized to accommodate the birds, providing comfort, depriving the animals of direct contact with excretions and with the floor, also to avoid temperature variation inside the poultry house. However, it provides shelter, hiding place and food for some insects and mites, especially ectoparasites, the principal pests present...

Eggshell exposure to both, field and storage toxigenic fungi, is of concern due to their possible metabolites transmission into the inner egg. The presence of fungi contamination in the nests environment, is expected due to its substrate, optimal temperature and humidity.In addition, the age of hens and eggshell increasing pore numbers together wit...

Contamination and biodegradation changes of poultry litter that may occur during the breeding stages of poultry and may affect chicken health and meat product safety have been studied. The living organisms most isolated period were insects (mainly Alphitobius sp. and Liposcelis sp.), mites (Acarus sp. and Dermanyssus sp.) and fungi (Trichoderma sp....

Poultry companies develop technical standards in which insecticides from the Pyrethroid Group are used to control insects and ectoparasites in aviary environment. This work presents an investigation through scanning electron microscopy on the macrofauna identification that develops in the poultry house. Although those living organisms are not harmf...

This study isolated Alphitobius diaperinus (live and dead) insects from shed's aviary bed to investigate their fungi spores distribution (that affects chicken health and meat production) and their accumulation sites (dorsal & ventral) characteristics by different microscopies (stereo and scanning electron). Despite live beetles being the main fungi...

The control of poultry farming beetles (Alphitobius diaperinus Panzer-Coleoptera, Tenebrionidae) infestation around the world is based exclusively on Pyrethroid Group (cypermethrin) insecticide application (during the 45 days of poultry breeding). Some studies report beetles population's resistance, reinforcing the need of alternative methods for b...

Fungos e suas condições de armazenagem (umidade) e a contaminação por micotoxinas em alimentos oferecidos para ovinos foram avaliados. Animais da raça crioula criados na Fazenda Ressacada-UFSC e com saúde debilitada. Com as amostras de (a) feno de alfafa (Medicago sativa L.) estavam armazenadas em 3 pontos (entrada do galpão, aprisco e sala), além...

The quality and safety of maize (Zea mays L.) from different grain storage units (GSUs), located in the main producing region of Rondonia State (RO), Northern Brazil were evaluated. Maize grains (n= 76) stored in four GSUs were collected from July to November 2014 and evaluated for grain damages, humidity, fungi and fumonisins (FBs) content. The cl...

Realizou-se uma análise crítica dos dados obtidos do Programa de Análise de Resíduos de Agrotóxicos (PARA) da Agência Nacional de Vigilância Sanitária (ANVISA) sobre os resíduos de agrotóxicos do grupo químico ditiocarbamato (DTCs) em maçãs (Malus domestica Borkh) comercializadas in natura durante dez anos no pais. Foram analisadas 1422 amostras de...

Chicken (Gallus gallus domesticus L.) cuts yield of wing (drummette / middle joint / tip), breast (fillet / tenderloin) and leg (drumstick / thigh / feet) of two specific hybrids (Cobb 500 Slow - CB-Slow and Hubbard Flex - HB-Flex) were evaluated. A total of 150 birds of each hybrid (grown in separate sheds under same management) were utilized for...

Dried distillers grains with soluble (DDGS) are co-products of the ethanol industry using corn as a feedstock. Because of its nutritional composition with high content of protein and fiber, combined with low cost, DDGS has been used in animal feed production, although still little known in Brazil for this application, as well as in humans for food....
