System for tracing animal products
The present invention provides a genetic testing system that ensures complete traceability of animals and food products and involves a method of uniquely identifying animals for data collection, records management and retrieval purposes involving a novel method of genetic analysis using individual DNA fingerprinting of parentage of individual animal to effectively provide for full traceability of animals from birth to consumption.
1. A method of tracing an animal product to its system or farm of origin comprising:
obtaining a sample of said animal product;
genotyping said animal product utilizing a DNA marker based system to obtain genotyping information;
comparing the genotyping of said animal product to a reference database, wherein said reference database consists of DNA marker profiles of parental animals unique to a system or farm, or to different systems or farms; and
analyzing said genotyping information with said reference database to determine a system or farm of origin for said product.
2. The method of claim 1 wherein said genotyping is selected from the group consisting of microsatellites, single nucleotide polymorphisms, amplified fragment length polymorphism and deletions and insertions of all, or part of said DNA marker profile.
3. The method of claim 1 wherein said DNA marker based system comprises the identification of between 10 and 100 microsatellite markers to identify a selected animal product to originate from inside or from outside the controlled system or farm of origin.
4. The method of claim 3 wherein said DNA marker based system further comprises the identification of between 20 and 50 microsatellite markers to identify a selected animal product to originate from inside or from outside the controlled system or farm of origin.
5. The method of claim 1 wherein said animal product information contains information selected from the group consisting of sample date, animal location, animal status, sample shipping information and sample storage information as well as animal phenotype information.
6. The method of claim 1 wherein said animal product is a farmed animal species.
7. The method of claim 1 wherein said animal is selected from the group consisting of: bovine, porcine, poultry, ovine, goats, fish, shellfish, and shrimp.
8. A system for genetically identifying a farm or system of origin of an animal from which an animal product is derived comprising:
genotyping information of said animal Product utilizing a DNA marker based system;
comparative data on the genotyping information of said animal product with known animal genotypes in a reference database said reference database consisting of genotype information of parental animals that is unique to each system or farm; and
analytical data comprising locating matching genotypes in said reference database to identify the system or farm of origin of said animal.
9. The system of claim 8 wherein said animal product information contains information selected from the group consisting of sample date, animal location, animal status, sample shipping information and sample storage information as well as animal phenotype information.
10. The system of claim 8 wherein the genotyping information is selected from the group consisting of genetic mapping, genetic background, genetic screening related to said parental animals or said parental animal samples.
11. The system of claim 8 wherein said genotyping information is selected from the group consisting of microsatellites, single nucleotide polymorphisms, amplified fragment length polymorphism and deletions and insertions of all, or part of said DNA marker profile.
12. The system of claim 8 wherein said DNA marker based system comprises between 10 and 100 microsatellite markers to identify a selected animal product to originate from inside or from outside the controlled system or farm of origin.
13. The system of claim 12 wherein said DNA maker based system further comprises between 20 and 50 microsatellite markers to identify a selected animal product to originate from inside or from outside the controlled system or farm of origin.
14. The system of claim 8 wherein said animal product is a farmed animal species.
15. The system of claim 8 wherein said animal is selected from the group consisting of bovine, porcine, poultry, ovine, goats, fish, shell fish, and shrimp.
16. A method of tracing an animal product to its system or farm
of origin comprising:
obtaining a sample of said animal product;
genotyping said animal product utilizing a DNA marker based system to obtain genotyping information;
comparing the genotyping information of said animal product to a reference database, wherein said reference database consists of DNA marker profiles of sires unique to different systems or farms; and
analyzing said genotyping information with said reference database to determine a system or farm of origin for said product.
