Anthrax outbreak: BAU launches field operation in affected areas

A research team from Bangladesh Agricultural University (BAU) has recently initiated a field operation in several anthrax-affected regions of Sundarganj upazila in Gaibandha to trace the source and pattern of infection among livestock.

 

Led by Professor Dr. Md. Shahiduzzaman of the Department of Parasitology, the team visited infected farms and nearby villages to assess the extent of the outbreak, routes of disease transmission, and farmers’ awareness of anthrax prevention and control measures.

 

The team also included Professor Dr. Md. Amimul Ehsan and Professor Dr. Azimun Nahar from the Department of Medicine, Professor Dr. Jahan Ara Begum from the Department of Pathology, Professor Dr. Muhammad Tofazzal Hossain from the Department of Microbiology and Hygiene, Dr. Jayedul Hassan (Member Secretary), and Assistant Professor Saifur Rahman.

 

The investigation team was formed under the direction of Professor Dr. Md. Bahanur Rahman, Dean of the Faculty of Veterinary Science at BAU, following reports of anthrax outbreaks in parts of Gaibandha and Rangpur districts.

 

According to Professor Ehsan, the main objective of the investigation is to determine the exact causes of local anthrax outbreaks and recommend effective preventive measures to avert future incidents.

 

Field observations revealed that many villages had not received livestock vaccination against anthrax. Farmers also lacked proper knowledge about carcass disposal. Interviews with locals indicated that several people became infected while slaughtering sick cattle or handling contaminated meat. At least 11 human infections have been confirmed so far.

 

The team found that carcasses of infected cattle and goats were often buried in shallow pits or discarded in open spaces, allowing anthrax spores to spread through rainwater and floods into nearby soil and rivers. Contaminated grass or water used as animal feed may have facilitated further transmission, the team suspects.

 

The researchers stressed that rapid quarantine of affected areas, proper burial of carcasses at least 6–8 feet deep, and disinfection with quicklime are essential for controlling the spread. They also emphasized strengthening vaccination and community awareness programs.

 

“Improper disposal of animal carcasses is one of the main reasons behind anthrax transmission,” said Prof. Shahiduzzaman. “If timely measures are not taken, the spores can remain active in soil and water for years.”

 

Upazila Livestock Officer Dr Biplob Kumer Dey said vaccination efforts are ongoing in the affected areas. “If all livestock are brought under annual vaccination, anthrax can be completely controlled,” he added, calling for more trained field personnel and resources.

 

The BAU research team also coordinated with local livestock officials to provide technical guidance on vaccination, carcass management, and awareness campaigns. The team expects their findings will contribute to national policy planning for anthrax prevention and control.
