Toxic substances, including aflatoxin B1, melamine and cyanuric acid, have been found in 11 samples of 20 dry dog food and 19 dry cat food products tested by Hong Kong’s Consumer Council.
According to an RTHK report, the level of Aflatoxin B1, which can cause liver cancer and hurt the immune systems of animals, was about 1 to 2 micrograms per kilogram in seven dry dog food samples.
The Pedigree- and No Frills-branded products contain the highest amount of this toxin among similar products, the Consumer Council is reported to have said. However, none of the tested samples saw their contamination levels exceed the European Union’s standard.
Animals ingesting the toxin over a long period will get tired easily, are likely to throw up, have low appetite and suffer dysentery with blood.
Among cases of dry cat food contamination, melamine was found in Iams dry cat food and Solid Gold dry food while cyanuric acid was found in Purina Pro Plan and First Choice dry cat food.
Although the amount did not exceed the standards of the United States and European Union, the combination of the two toxins may cause acute renal failure, the Consumer Council warned.
