ANIMAL SCIENCE
Non Technical Summary
Food safety research leading to implementation of interventions will be emphasized, particularly with regard to emerging microbiological issues (e.g., Multi-Drug Resistant Salmonella, Listeria monocytogenes, Johne's disease, zoonotic animal diseases, etc.) using molecular techniques. Investigators will identify ambiguity in meaning regarding terms of trade, and characterize deficiencies with trading-partner definitions. Studies to improve market access for beef products in export destinations will be conducted primarily to address bilateral technical barriers to trade, with initial emphasis on improving market access for U.S. meats. For the instrument grading technology research, projects will be conducted to demonstrate proof of concept. This will entail evaluating beef steaks varying widely in tenderness. Appropriate software will be developed based on these results. Industry prototypes will be constructed and tested for the most promising approaches. In-plant validation will complete this initiative.

Goals / Objectives
1. Enhance palatability, processing, and marketing of beef by studying instrument grading, beef flavor and tenderness technologies, and carcass cutting strategies 2. Develop science-rooted strategies and technologies to reduce foodborne illness and improve the effectiveness of policies related to food safety and trade. 3. Determine factors influencing domestic and international consumer preferences for beef. 4. Assess supply chain management strategies to identify and overcome barriers that interfere with the transmission of consumer preferences to producers 5. Evaluate the cost/benefit of traceability and assess its value in market-based programs
Project Methods
Multiple projects will utilize well-known protocols for measuring microbiological, quality, and desireability aspects associated with red meats. Bioassays will be utilized for measuring TSE transmissability. Additionally, novel molecular, enzymatic and immunochemical approaches to address food safety, trade, and quality issues will be incorporated including, but not limited to, PCR, Western blot, ELISA, PFGE, ribotyping, etc. Instrument studies will initiate use of new technologies which include measures of degradative enzyme activities and high-resolution digital imaging.

Impacts
Researchers developed a methodology for detection of BSE Specified Risk Material in animal products. Additionally, developed antimicrobial interventions to reduce the likelihood of Salmonella contamination in raw poultry intended for use in the manufacture of frozen, not-ready-to-eat entrees. Provided food safety assistance for small meat and poultry processors through development and implementation of industry best practices. Researchers evaluated the effectiveness of FreshCase technology to extend the shelf-life of whole muscle pork and ground pork sausage and whole muscle beef and ground beef. Conduted a comprehensive consumer panel palatability rankings and establishing baseline tenderness of American lamb meat. Finally, researchers participated in national audits to determine the status of beef, pork and lamb quality in the United States.

Impacts
Researchers evaluated the impact of pathogens in non-intact beef products during cooking, and published means by which bacterial death is maximized. Work continued on efforts to reduce risk of E. coli O157:H7 and non-O157 STEC contamination in beef products destined to become a non-intact product; validations for several intervention chemicals at industrial operating parameters should prove very beneficial to companies wishing to conform to expected new FSIS policies regarding validation due in 2012. Lastly, Center scientists validated a relatively new and "organic" concept for antimicrobial decontamination of meat products; that of Citrus Essential Oils. Results suggested that opportunities may exist to use Citrus Essential Oils in beef intervention systems, particularly on products destined for labeling with "natural" or "organic" production terminology.

OUTPUTS: 1. Enhance palatability, processing, and marketing of beef by studying instrument grading, beef flavor and tenderness technologies, and carcass cutting strategies. 2. Develop science-rooted strategies and technologies to reduce foodborne illness and improve the effectiveness of policies related to food safety and trade. 3.

PARTICIPANTS: Nothing significant to report during this reporting period. TARGET AUDIENCES: Nothing significant to report during this reporting period. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Impacts
1. Beef instrument grading systems were approved for use by USDA-AMS in 12 plants during 2009-2010, and grading of carcasses was initiated in six new plants during 2010. Research continues to develop new high-resolution imaging technologies to more accurately predict beef eating quality. 2. Studies continued to address decontamination/prevention strategies for use with Ready-to-Eat food products. Additional studies were completed addressing pre-harvest food safety management. 3. We examined the impacts of animal identification and tracing systems adoption on the U.S. meat and livestock industry and found that a modest increase in domestic demand for beef would completely offset the costs of an animal identification system. Similarly, an increase in export demand for beef, equivalent to Japan's beef export market share prior to the 2003 U.S. BSE discovery, would be enough to offset animal identification system costs.

TARGET AUDIENCES: Not relevant to this project. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Impacts
A)Beef instrument grading systems were approved for use by USDA-AMS in 12 plants during 2009, and grading of carcasses was initiated in six plants during 2009. Several technologies for use in prediction of tenderness were validated in 2009, and research continues to develop new high-resolution imaging technologies to more accurately predict beef eating quality. B) Studies continued to address decontamination/prevention strategies for use with Ready-to-Eat food products. Additional studies were completed addressing pre-harvest food safety management. A longitudinal study was conducted to investigate the nature of E. coli O157:H7 colonization of feedlot cattle over the final 100 to 110 days of finishing. Animals were classified as having persistent shedding (PS), transient shedding (TS), or nonshedding (NS) status if they consecutively shed the same E. coli O157:H7 genotype (based on the multiplex PCR profile), exhibited variable E. coli O157 shedding, or never shed morphologically typical E. coli O157, respectively. Overall, 1.0% and 1.4% of steers were classified as PS and NS animals, respectively. Molecular characterization of 132 isolates yielded 32 unique PFGE types. One predominant type accounted for 53% of all isolates characterized and demonstrated an enhanced ability to adhere to intestinal epithelial cells compared to isolates belonging to less common PFGE types, but which exhibited equal virulence expression. Our data support the hypothesis that certain E. coli O157:H7 strains persist in feedlot cattle, which may be partially explained by an enhanced ability to colonize the intestinal epithelium. C) A benefit‐cost analysis of the U.S. National Animal Identification System (NAIS) was conducted. NAIS is designed to protect the national livestock and poultry health and maintain market access. If we do nothing to adopt NAIS, and nothing happens to export markets, the result is no cost, no market loss. If we do nothing and we lose market access, which we believe is likely, the beef industry will suffer losses ($18.25 per head if we do not adopt NAIS and lose 25% of export market share). A 23% increase in beef export demand would completely pay for 70% adoption of full animal ID and tracing in the US beef herd over a 10‐year period. Overall, NAIS adoption would result in large positive net returns to the industry with a very small increase in domestic beef demand. A second study provided a series of recommendations for the U.S. to consider as it continues to develop the NAIS by interviewing packers and renderers in the Canadian cattle industry. The authors recommended that NAIS: (1) be a mandatory program; (2) operate with a single national database to avoid creating unnecessary and confusing database differences; (3) standardize radio frequency identification technology and establish specific requirements for tag manufacturers to meet in order to be eligible to sell official animal identification tags; (4) be implemented as a phase-in program; and, (5) be harmonized with the identification programs of trading partners to extend their potential value across borders.

OUTPUTS: 1-Enhance palatability, processing, and marketing of beef by studying instrument grading, beef flavor and tenderness technologies, and carcass cutting strategies. 2-Evaluate the cost/benefit of traceability and assess its value in market-based programs. PARTICIPANTS: Not relevant to this project. TARGET AUDIENCES: Not relevant to this project. PROJECT MODIFICATIONS: Not relevant to this project.

Impacts
1-Large numbers of finished beef cattle now are marketed on grid-based pricing systems. Carcasses that do not conform to mainstream specifications generally do not achieve full value due to failure to achieve premium prices. Research was conducted to evaluate beef carcass ribeye area at the 12th and 13th rib interface (LMA) and its relationship to portion sizing acceptability of other muscles in the carcass. Sixty beef carcass sides of varying LMA sizes (between 67.74 and 166.13 cm2) were fabricated into 14 individual cuts. Retail portion size (g/1.27-cm steak), along with cut surface area and dimensions, were recorded from steaks cut perpendicular at the midpoint of the longitudinal axis of each muscle. Subsequently, a nationwide survey was conducted with foodservice chefs and retail meat merchandisers to evaluate acceptability of portion sizes and dimensions of individual muscle cuts. Results showed that LMA was not associated with retail portion size for 6 of the 14 muscles. Similarly, LMA did not affect surface area of the face of the steak from 6 of the 14 muscles. Muscles for which portion characteristics were related to carcass LMA were further evaluated in the survey. Many muscles were still acceptable to retail merchandisers and foodservice chefs in portion size, even though carcass LMA was outside the range of commercially acceptable sizes. This study demonstrate that carcass LMA is not an accurate determinant of the size, and subsequent acceptability, of other muscles in the carcasses and may not be a good determinant of the remaining value of the beef carcass; it will be used by industry to modify current beef pricing practices. 2-A final report that analyzed the benefits and costs of the national animal identification system (NAIS) was completed and submitted to USDA-APHIS in early October 2008. The primary purpose of this project was to conduct a comprehensive assessment of the economic benefits and costs of NAIS in the U.S., including premise registration, animal identification systems, and animal movement reporting for major species of cattle, hogs, sheep, equine, and poultry and, to a limited extent, minor species of bison, goats, cervids, and camelids. The final report currently is under review.
