Salmonella fecal excretion control in broiler chickens by organic acids and essential oils blend feed added Rev. Bras. Ciênc. Avic.
Borsoi,A; Santos,LR; Diniz,GS; C. Salle,CTP; Moraes,HLS; Nascimento,VP.
Salmonellosis is an important disease with economic impact as it may affect animal performance and may result in foodborne disease in humans through the eggs and carcass contamination. Regarding the Salmonella control, it is possible to decrease its fecal excretion and the contamination of chicken carcasses by adding organic acids to the feed or drinking water at appropriate times. The aim of this study was to test a blend of organic acids and essential oils in broilers challenged with Salmonella Enteritidis (SE), and to verify the fecal excretion of Salmonella. Sixty broilers were placed in four groups. One group was the negative control. Another group was orally inoculated at 1 day-old with 10(5) CFU/mL of SE as a positive SE control. Two groups (T3 and...

In vitro efficiency of disinfectants against salmonella enteritidis samples isolated from broiler carcasses Rev. Bras. Ciênc. Avic.
Cardoso,MO; Ribeiro,AR; Santos,LR; Borsoi,A; Pilotto,F; Rocha,SLS; Nascimento,VP.
The threat to public health represented by Salmonella is at least partially a consequence of its ecology in poultry hosts. Good manufacturing practices in the processing plant can reduce the contamination of poultry products, and critical control point principles are essential throughout the chain production. One procedure adopted in critical points control to prevent and to reduce Salmonella in farms and poultry products is the use of disinfectants. This study aimed at evaluating disinfectant efficiency against Salmonella enteritidis samples isolated from broiler carcasses in Rio Grande do Sul State between 1995 and 1996. The tested disinfectants were: phenol 1:256, quaternary ammonium 1:2500, glutaraldehyde 1:200, and iodine 1:500, with contact times of...

Risk factors and likelihood of Campylobacter colonization in broiler flocks Rev. Bras. Ciênc. Avic.
Kuana,SL; Santos,LR; Rodrigues,LB; Borsoi,A; Moraes,HLS; Salle,CTP; Nascimento,VP.
Campylobacter was investigated in cecal droppings, feces, and cloacal swabs of 22 flocks of 3 to 5 week-old broilers. Risk factors and the likelihood of the presence of this agent in these flocks were determined. Management practices, such as cleaning and disinfection, feeding, drinkers, and litter treatments, were assessed. Results were evaluated using Odds Ratio (OR) test, and their significance was tested by Fisher's test (p<0.05). A Campylobacter prevalence of 81.8% was found in the broiler flocks (18/22), and within positive flocks, it varied between 85 and 100%. Campylobacter incidence among sample types was homogenous, being 81.8% in cecal droppings, 80.9% in feces, and 80.4% in cloacal swabs (230). Flocks fed by automatic feeding systems...
