Microplastics, cadmium found in hilsa; adviser flags health risks

Hilsa, Bangladesh’s national fish, has been found contaminated with microplastics and cadmium, raising serious concerns for human health, Fisheries and Livestock Adviser Farida Akhter said today (24 January).

“Industrial effluents from Narayanganj and other districts are flowing into the Shitalakshya and eventually the Meghna River, posing a severe threat to hilsa and other aquatic life,” Farida Akhter said at the third convocation of ASA University Bangladesh (ASAUB) held at the Bangladesh-China Friendship Conference Centre in Agargaon.

The adviser warned that hilsa contains harmful substances such as microplastics, lead, and cadmium, which is extremely alarming. 

“Industrial waste threatens the very existence of hilsa and other aquatic creatures. Keeping our rivers pollution-free is a vital national duty—not just the government’s responsibility, but one that requires active public participation and awareness,” she said. 

Farida added that the Ministry of Fisheries and Livestock is responsible not only for cattle, goats and poultry but also for the protection of all animals, including dogs and cats. Without proper vaccination, dogs are at higher risk of rabies and other diseases. The adviser urged people to fulfil their responsibilities towards animals.

Addressing students, she encouraged youth to take an active stance against corruption, environmental pollution, and unhealthy practices, emphasising that protecting the nation for future generations is everyone’s duty.

Highlighting the importance of natural resources, the adviser said, “Bangladesh is not a poor country. Our people’s skills, natural resources, potable water, crop seeds, and genetic resources are our greatest strength. Future global conflicts may revolve around water, seeds, or natural resources. Protecting these resources and ensuring the nation’s security is a critical responsibility for the younger generation.”

She also urged students to remain health-conscious, warning that smoking and tobacco use cause severe health problems. “Boys and girls often believe smoking or using drugs makes them ‘smart’ or fashionable, but in reality, it leads to heart disease, cancer, and other illnesses. A new law to control tobacco use has recently been enacted and is mandatory for everyone.”

Farida advised students to maintain the dignity of their degrees through good conduct, professionalism and character.

Around 4,000 students received degrees at the convocation, including 2,096 undergraduates and 1,900 postgraduates.

The adviser also presented six students with the Chancellor’s Award and nine students with the Vice-Chancellor’s Award for outstanding performance.
