Thermographic Images to Measure Health Risks of Workers Exposed to Artificially Refrigerated Environments
Provedor de dados: Revista Brasileira de Ciência Avícola
Autores: Takeda,F; Moro,A; Martins,N.
ABSTRACT Thermography generates high-resolution imagery in real time and is a non-invasive and painless technique devoid of physical contact or exposure to any type of radiation. This technique has been successfully applied to different areas, such as health- and safety-related applications, to control cold risk in workers exposed to low-temperature environments. Thus, this study aims to analyze skin temperature variations in three body parts of the upper limbs (fingers, the center of the hands and wrists on both the left and right sides of the body) caused by exposure to low temperatures in air-conditioned and artificially controlled work environments. The objective is to assess thermography’s adequacy in controlling workers’ health risks. This study used...

Provedor de dados: Revista Brasileira de Ciência Avícola
Autores: Dias,NF; Tirloni,AS; Reis,DC; Moro,ARP.
ABSTRACT This study analyzed the effect of job rotation on the risk of developing UL-WMSDs in a poultry slaughterhouse with 1,200 workers. Three organizational settings were evaluated (“without job rotation”, “with job rotation - tasks &gt;1h” and “with job rotation - tasks &lt;1h”) using the OCRA Checklist method and the fulfillment of requirements for the implementation of rotations established by the Brazilian Regulatory Standard NR-36. The OCRA score of the right upper limbs (16.5±5.7) were significantly higher (p&lt;0.001) relative to the left upper limbs (15.0±5.6). The average scores on all three organizational conditions presented moderate risk. There was a significant difference between the scores of the conditions “without job rotation” and “with...

Provedor de dados: Revista Brasileira de Zootecnia
Autores: Vieira,Frederico Márcio Corrêa; Silva,Iran José Oliveira da; Barbosa Filho,José Antonio Delfino; Vieira,Afrânio Márcio Corrêa.
This work aimed to assess the effects of preslaughter lairage time on the welfare and mortality of broilers transported in different farm-abattoir distances. It was evaluated 215 poultry transport trucks from a commercial poultry slaughterhouse from 2006 to 2007. Data were obtained from the holding area acclimatized through fans and water misting in the mornings, afternoons and at night. The thermal variables (temperature and relative humidity), distance, lairage time and density of birds per cage were considered in the analysis. The effects of distance and lairage time were important in the variation of rectal temperature of the animals and on the number of dead animals per truck. Two models were developed (mean and dispersion), for each response variable...

ABSTRACT The objective of the present research was to study the incidence of broiler carcass condemnations over eleven years and identify the productive phase that causes greater loss in slaughter process. The origin of these condemnations was determined before and after fasting. Evaluated broilers were reared in positive pressure warehouses and slaughtered between 28 and 34 days old with carcass weight ranging from 0.7 to 1.4 kg. Fasting occurred, on average, 9 h before the slaughter. Condemnation and slaughter data were collected from 2004 to 2014 in a slaughterhouse with slaughter capacity of 120,000 broilers/day. The causes of rearing condemnations were airsaccullitis, arthritis, abscess, ascites, cachexia, cellulitis, colibacillosis, dermatosis,...

Autores: Falavigna-Guilherme,A.L.; Silva,K.; Araújo,S. M.; Tobias,M.L.; Falavigna,D.L.M.
The aim of this work was to verify the occurrence of bovine and swine cysticercosis in animals slaughtered at the Abatedouro Municipal de Sabáudia, Paraná State. The number of daily-abated animals, the number of animals with cysticercus and the number and location of the cysticercus in the animals in a period of twelve months were collected. From 1046 swines slaughtered none showed cysticercus, but 36/out of 389 bovines (9.3%) were contaminated. Head was the most parasited region, followed by heart, tongue and liver. The absence of contamination observed in swines and the low contamination of the bovines reinforce the efficiency of the control measures accomplished in Paraná State.

Provedor de dados: Brazilian Archives of Biology and Technology
Autores: Beux,Simone; Nunes,Ezequiel; Barana,Ana Cláudia.
The effectiveness of the anaerobic treatment of effluent from a swine and bovine slaughterhouse was assessed in two sets of two-phase anaerobic digesters, operated with or without temperature control. Set A, consisting of an acidogenic reactor with recirculation and an upflow biological filter as the methanogenic phase, was operated at room temperature, while set B, consisting of an acidogenic reactor without recirculation and an upflow biological filter as the methanogenic phase, was maintained at 32°C. The methanogenic reactors showed COD (Chemical Demand of Oxygen) removal above 60% for HRT (Hydraulic Retention Time) values of 20, 15, 10, 8, 6, 4, and 2 days. When the HRT value in those reactors was changed to 1 day, the COD percentage removal decreased...

Concerning the reduction of preslaughter death losses, high temperature and relative humidity in the tropics are the major concerns regarding broiler survival prior slaughtering. However, the relationship between different lairage times under controlled environment and the thermal condition outside the holding area is still unclear. Thus, the aim of this study was to compare different intervals of lairage time with different environmental temperature and relationship with poultry mortality rates. A study was conducted in a commercial poultry abattoir in the State of Sao Paulo, Brazil, in the year of 2006. The historical data set from 13,937 trucks, about broiler mortality during preslaughter operations, was given by the abattoir. Factors that influence the...

Clostridium perfringens is an anaerobic Gram-positive bacterium known as common pathogen for humans, for domestic and wildlife animals. Although infections caused by C. perfringens type C and A in swine are well studied, just a few reports describe the genetic relationship among strains in the epidemiological chain of swine clostridioses, as well as the presence of the microorganism in the slaughterhouses. The aim of the present study was to isolate C. perfringens from feces and carcasses from swine slaughterhouses, characterize the strains in relation to the presence of enterotoxin, alpha, beta, epsilon, iota and beta-2 toxins genes, using polymerase chain reaction (PCR) and comparing strains by means of Pulsed field gel electrophoresis (PFGE)....
