Impact of Bovine Tuberculosis on Public Health Hazards from Frozen Bovine Meat Consumption in World

Bovine Tuberculosis or bTB is a chronic zoonotic infection at abattoir in India. Despite its existence in India very little information available about Bovine Tuberculosis extent or nature. Generally, frozen buffalo meat is exporting from India to many other countries. The existence of Mycobacteria spp in bovine meat increases the risk of zoonosis transmits from animal to human. To validate the risk assessment of BTB in frozen buffalo meat and to validate the hypothesis, current study was designed to record the prevalence of Mycobacterium bovis, M. tuberculosis and M. cosmeticum from the frozen buffalo meat and chances of transmission of disease. There are few samples of microscopically infected lesion tested through Zeihl-Neelsen staining technique from infected area of buffalo and found AFB (Acid Fast Bacilli) positive for bTB. Approximately 45 samples of frozen buffalo meat sample processed in Lowenstein Jensen media containing glycerol, pyruvate, egg yolk and found 27 samples positive of Mycobacteria. Among them M. bovis positive in 24 samples, M. tuberculosis positive in one sample and M. cosmeticum positive in 5 samples. Apart from that 25 samples water at abattoir also tested for risk assessment of BTB, but observed as negative. These results indicate that probably all buffalo carcasses inspected in slaughter area in New Delhi, India, are suggestive of Bovine Tuberculosis and consistent serious threat for rest of the world for public health threat. To overcome the overall BTB disease inspection of carcasses during post mortem should be mandatory, diagnostic examination carried out in house laboratory, sanitation and disinfection ratio should maintain at abattoir.
