“…Lower frequencies farms with an intensive system of Rio de Janeiro were evidenced by Nishi et al (2000) in Minas Gerais (38.6%) and São Paulo (39.7%). The high parasite positivity in traditional family systems was also reported by Lai et al (2011) in pigs of Chongqing, in China, without significant difference relating to the intensive system.…”

“…were the most detected in both production systems, with a significant difference among them being the most evident parasitism association between these protozoa (B. coli and Entamoeba sp., B. coli and coccidia). Results that differ from the farms of Rio de Janeiro found by Lai et al (2011) showed that B. coli in traditional and industrial farming respective- The percentages were calculated dividing the number of samples positive for parasites by the subtotal. Entam = Entamoeba sp., A. suum = Ascaris suum; B. coli = Balantidium coli; Cocc = Coccidia; S. ransomi = Strongyloides ransomi, H = Petrópolis, I = Itaperuna.…”

“…In 3636 fecal samples from pigs reared on farms with an intensive production system in Guangdong Province, China, Weng et al (2005) detected 47.5% of positivity for B. coli as well as, T. suis (5.7%), Ascaris suum (5.2%), strongyles (2.5%) and coccidia (24.9%). Also in China, the city of Chongqing, Lai et al (2011) However, in the state of Rio de Janeiro the information on the prevalence of parasitic infections in pigs produced in different raising systems is limited. In this context, the objective of this work was to evaluate the estimated prevalence of gastrointestinal parasites of pigs in family and industrial farms in different cities in the state of Rio de Janeiro, correlating the positivity of parasites with the different categories of pigs in intensive systems and also the frequency of trophozoite B. coli, according to fecal consistency.…”

From 2012 to 2013 were surveyed gastrointestinal parasites from pig farms located in different municpaliyies in the state of Rio de Janeiro. Fecal samples from 790 pigs were collected from the rectum on 88 family farms and 702 farms with industrial production. The samples were subjected to Faust et al., Sheather, Ritchie, Lutz and direct examination faecal techniques. The estimated parasite prevalence was 93.1% in family farms and 59.1% in industrial farms. Balantidium coli, coccidia and Entamoeba sp. were the parasites with the highest frequencies, and the male and female reproductive categories and fatteners pigs the most infected (p<0.05). Trophozoites of B. coli were most evident in stool samples from semi-solid followed by solid and diarrheal consistencies. Strongyles eggs and Trichuris suis have been detected exclusively in family farms. Ascaris suum eggs and Strongyloides ransomi showed low frequency. The high degree of parasitism, especially protozoa, indicates the need to reassess the management of pigs in both types of production.

“…In contrast, a microscopic investigation of pig faeces from Sardinia (Italy) show a much lower prevalence (15.5%) of Balantidium coli [21]. In China, Weng et al [22], show an infection rate of 47.2% in pigs from intensive farms in Guangdong Province, and more recently a lower prevalence of B. coli was found (22.12%) in Chongqing [23].…”

Balantidium coli is a zoonotic protozoan parasite, and pork is considered the major source of Balantidium infection in humans. Transmission is direct and commonly occurs through the ingestion of water and food, especially vegetables, contaminated with infectious cysts. Ingestion of meat contaminated, with faecal material during the evisceration process, can represent a potential risk of B. coli transmission. In order to determine the rate of B. coli infection in pigs regularly slaughtered at abattoirs in the province of Messina (Sicily, Italy), faecal samples of 242 pigs (122 commercial hybrid and 120 Nero Siciliano pigs) were collected and evaluated by standard methods for the presence of trophozoites and/or cysts. A total of 105 of the commercial hybrid (86.06%), but only 44 of the Nero Siciliano (36.66%) pigs, were identified as positive for B. coli infection. The results obtained, may be linked to the type of farming employed.

RESUMO.O presente trabalho tem por objetivo apresentar dados coletados em 11 propriedades que abastecem um frigorífico de Santa Catarina. Foram analisados 2.691 suínos abatidos no ano de 2016 sobre as principais causas de condenações de vísceras vermelhas ou comestíveis em abates. Foram identificadas as seguintes causas por condenações de carcaças: pneumonia enzoótica 52,08%, aspiração por sangue 20,28%, aspiração por líquido 17,01%, aderência de pleura 3,04%, atelectasia pulmonar 0,89%, enfisema pulmonar 0,18%, abscesso pulmonar 0,26%, pleuropneumonia 2,52%, lesão por Ascaris suum 16,05%, perihepatite 1,89%, cirrose hepática 3,04% e pericardite 6,91%. As principais condenações foram por pneumonia enzoótica, aspiração por sangue, lesão por Ascaris suum e pericardite. Durante a inspeção as lesões podem ser provenientes de diferentes fatores, entre eles, falhas no processo tecnológico de abate, ausência de um programa de vacinação e erros de biossegurança nas propriedades, associado com o manejo precário. Diante disso, a redução da prevalência das lesões que culminam em condenação das carcaças pode ser minimizada com o treinamento de funcionários para minimizar as perdas econômicas na indústria e para os produtores de suínos juntamente com um rigoroso controle sanitário nas granjas. Palavras-chave: carcaças, inspeção sanitária, lesões post mortem, suínos terminados Economic damages by condemnation of viscera in red of pigs slaughtered Santa CatarinaABSTRACT. The present work has as objective, with data collected in 11 properties that provide a refrigerator of Santa Catarina. A total of 2.691 pigs slaughtered in 2016 were analyzed as the main causes of condemnation of red or edible viscera in slaughter. Encephalic pneumonia 52.08%, blood aspiration 20.28%, fluid aspiration 17.01%, pleural adhesion 3.04%, pulmonary atelectasis 0.89%, pulmonary emphysema 0.18%, pulmonary abscess 0.26%, pleuropneumonia 2.52%, Ascaris suum lesion 16.05%, perihepatitis 1.89%, cirrhosis 3.04% and pericarditis 6.91%. As main condemnations for enzootic pneumonia, blood aspiration, Ascaris suum injury and pericarditis. During the inspection as lesions can be disclosed of different factors, associated with precarious management, absent from a vaccination program and biosafety errors in properties, associated with poor management. In view of this, a reduction in the prevalence of injuries that culminate in condemnation of carcasses can be minimized by training employees to minimize economic losses in industry and to pig producers with strict sanitary control on farms.
