Established test methods for detecting foot-and-mouth disease virus (FMDV) rely on sample collection from live animals. However, circumstances exist in which it is not possible to collect the desired samples. Meat juice has been explored as an alternative for the detection of FMDV and has previously proven successful by real-time reverse transcription polymerase chain reaction and lateral flow strip test. Meat juice has not yet been assessed for the detection of antibodies to FMDV. This study, therefore, evaluated meat juice for the detection of antibodies to structural proteins by existing serotype-specific solid phase competitive enzyme-linked immunosorbent assays. Antibodies to FMDV structural proteins were detected in meat juice from experimentally infected pigs beginning 6- or 7-days post-infection (DPI) and continued until 21 to 28 DPI. Sera were tested in tandem and followed similar antibody detection patterns. The results show that meat juice can be used for detection of anti- FMDV structural protein antibodies.

UI	MeSH Term	Description	Entries
D008460	Meat	The edible portions of any animal used for food including cattle, swine, goats/sheep, poultry, fish, shellfish, and game.	Meats
D004797	Enzyme-Linked Immunosorbent Assay	An immunoassay utilizing an antibody labeled with an enzyme marker such as horseradish peroxidase. While either the enzyme or the antibody is bound to an immunosorbent substrate, they both retain their biologic activity; the change in enzyme activity as a result of the enzyme-antibody-antigen reaction is proportional to the concentration of the antigen and can be measured spectrophotometrically or with the naked eye. Many variations of the method have been developed.

D005536	Foot-and-Mouth Disease	A highly infectious disease caused by FOOT AND MOUTH DISEASE VIRUS that affects mammals of the ARTIODACTYLA order (CATTLE; SHEEP; GOATS; and PIGS) and is characterized by high fever followed by the appearance of blisters inside the mouth and on the feet.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
