♦ HC asks BFSA, BSTI to report what actions taken to check adulteration of milk, curd and cattle feed.

♦ No drug store can sell antibiotic for cattle without prescriptions from registered veterinary doctors.

Amid concerns about the quality of the packaged and non-packaged milk available in the market, Bangladesh Food Safety Authority (BFSA) has now detected lead, a harmful heavy metal, in pasteurised milk of 11 brands.

The companies are Milk Vita (state-run), Aarong Milk, Pran Milk, Dairy Fresh, Igloo Milk, Farm Fresh, Aftab Milk, Ultra Milk, Ayran Milk, Pura Milk and Safe Milk — all registered under Bangladesh Standard and Testing Institution (BSTI).

The BFSA carried out the test last month at the laboratories of six top government and nongovernment organisations — Bangladesh Atomic Energy Commission, Bangladesh Agricultural Research Institute, Bangladesh Council of Scientific and Industrial Research, Plasma Plus, WAFFEN Research and International Centre for Diarrhoeal Disease Research, Bangladesh.

The test also found both lead and cadmium in raw cow milk available in various markets in the capital, said BFSA lawyer Faridul Islam, who placed the report before the High Court yesterday.

The samples of the packaged milk were collected from various markets in the capital, while the samples of raw milk were collected from 50 selling points in the city.

It comes just two weeks after Dhaka University researchers found detergent and antibiotics for humans in packaged milk of some of the top brands who boast of their “superior” quality in advertisements — Milk Vita, Pran, Aarong, Igloo and Farm Fresh.

The antibiotics include levofloxacin, ciprofloxacin and azithromycin that are used mainly to treat bacterial infections in humans.

After the DU researchers published their findings, Kazi Wasi Uddin, additional secretary to the fisheries and livestock ministry, threatened them with legal actions if they failed to publish their study in a peer-reviewed journal.

A subsequent second test by the DU researchers on the same samples reconfirmed their findings, said Prof ABM Faroque, director of Biomedical Research Centre at DU, who led the research.

Experts say lead in milk can come from cattle feed and contaminated soil and can affect liver, kidney and bones.

According to the World Health Organisation, there is no known level of lead exposure that is considered safe for human body.

“If the soil is contaminated, lead enter into animal bodies through feed. The other source may be processed cattle feed. If the feed is contaminated, milk will be too,” said Mohidus Samad Khan, an associate professor at Buet’s Chemical Engineering department.


Receiving the BFSA report, the HC ordered the government to stop sale of antibiotics for cattle without prescriptions from registered veterinaries.

The court also expressed its frustrations over the authorities’ failure to ensure safe food, including milk, and ordered the BFSA and BSTI to report back to the court on their actions against adulteration of milk, curd and cattle feed.

The bench of Justice Md Nazrul Islam Talukder and Justice KM Hafizul Alam also noted that food adulteration was a “public health issue and not an issue of politics”.

“A government secretary has reportedly criticised the Dhaka University researchers who detected harmful substance in milk. But why? Tell us if milk has anything to do with politics. We should all work shoulder to shoulder in order to ensure safe food and sound health,” Justice Nazrul said.

The court also wondered how milk contaminated with lead and cadmium can be found in markets, and asked the BSTI and BFSA to keep food free of contamination for the sake of public health.

Someone claims there is hazardous substance in milk while another says milk is safe, the court said, referring to a recent BSTI report that claimed packaged milk was safe to drink.

However, the BSTI testing standards were set decades ago and are way below the international standards. Also, BSTI has no mechanism to detect pesticides and antibiotics.

During yesterday’s hearing, BSTI lawyer Sarkar MR Hassan told the court that the BSTI formed a committee to set an international standard about food consumption.

The HC took the issue of milk contamination so seriously that in February it ordered the Anti-Corruption Commission to investigate the adulteration of milk, curd, and fodder and take legal action against those responsible.

The court had also asked the BFSA to form a probe committee to identify the individuals and businesses involved in adulteration of dairy products and fodder in three months.

The HC then issued a rule on the authorities, including the BFSA chairman, members of Central Food Safety Management Coordination Committee and the BSTI chairman, to explain why their inaction and failure to prevent food adulteration should not be declared illegal.

At the time, the court had also asked them to explain why production, transport, and preservation of adulterated milk, curd, and fodder in shops, departmental stores, and open market should not be declared illegal.

The rule directed the respondents to explain why they should not be ordered to remove those from the market and bring those responsible to justice.

The February 11 order came after the National Food Safety Laboratory (NFSL) found excessive level of lead, pesticide, antibiotics and bacteria in raw cow milk. The study also detected high levels of chromium in cow feed.
