| CAHFSE Stage 1: Swine |
| |
|
|
Participating States |
| |
The CAHFSE project has successful partnerships with Iowa, Minnesota, North Carolina, and Texas for the Swine portion of the study, and Missouri is joining in late 2004. Partnerships are also being negotiated with additional states. These partnerships are critical to the success of this research, and we thank the animal health professionals and producers from these states for their cooperation. |
| CAHFSE Swine Study Objectives |
| |
Animal Health Objectives |
| |
- Assess the presence of bacteria that cause ileitis (Lawsonia intracellularis) in multiple age groups of weaned market pigs.
- Provide an epidemiological description of ileitis, including monitoring disease and death rates on affected farms.
- Relate onset and duration of infection with antibiotic-use patterns.
|
| |
Food Safety Objectives |
| |
- Describe the on-farm and in-plant trends in the prevalence of Salmonella, Campylobacter, generic E. coli, and Enterococcus spp.
- Characterize isolates with particular emphasis on their susceptibility to antibiotics and genetic relatedness
- Relate findings to on-farm management practices, including patterns of antibiotic use in market swine
|
| Benefits to Pork Producers
|
| |
By participating in CAHFSE, pork producers will be helping to improve the quality and safety of U.S. pork and the health of the U.S. swine herd. Benefits to CAHFSE participants include: |
| |
- Providing industry with an objective assessment of food-safety risks pertaining to antibiotic-resistant bacteria.
- Facilitating research on the relationships between management practices, pathogens, and antibiotic resistance.
- Quarterly summary of test results for ileitis and clinical report of ileitis in the herd
- Information the operation's practitioner can use to develop strategies to control ileitis
- Facilitating research on ileitis that may help identify risk factors associated with ileitis outbreaks.
|
|
| Critical Partnerships |
| |
The success of CAHFSE depends on government partnership with industry and other stakeholders. |
| |
- CAHFSE has been presented to and sanctioned by several committees of the National Pork Board, and has the support of the National Pork Producers Council and the American Association of Swine Veterinarians
- Involvement of private practitioners, producers, and slaughter / processing establishments are vital to the CAHFSE program
- Operations of various sizes and types from Iowa, Minnesota, North Carolina, Texas, and Missouri are participating or have participated in the swine portion of the CAHSE project, and operations from other states are being recruited to participate.
|
| Confidentiality |
| |
On-farm questionnaire data and test results will be managed by APHIS staff responsible for the National Animal Health Monitoring System (NAHMS), which has a proven track record for maintaining producer confidences. To ensure confidentiality, only summarized results will be released. No individual operations will ever be identified. |
| Data Collection |
| |
On-farm Collection |
| |
- Collect 60 blood samples from pigs of various ages and 40 fecal samples from pens containing late finisher pigs (quarterly)
- Complete quarterly questionnaire describing clinical signs consistent with ileitis, on-site production practices, and use of antibiotics
- Create quarterly reports of summarized results, including serological results
- Complete annual questionnaire describing facilities, general health, and management practices for the production sites
- Create annual reports of summarized results
|
| |
In-Plant Collection |
| |
- Plans call for collecting samples at slaughter and evaluating them for Salmonella, Campylobacter, Enterococcus spp., and generic E. coli.
- In-plant findings will be linked with on-farm questionnaire data and laboratory results.
