Both brands say their products are safe.
For decades, India's spice makers MDH and Everest have been ubiquitous in kitchens around the world with their products being essential ingredients in chicken and fish curries and vegetable dishes.
A Hong Kong sales ban on some of their products after a cancer-causing pesticide was found has triggered a wave of scrutiny, including in the United States, the Maldives, India and Australia. Both brands say their products are safe.
Here are some facts and background on the two brands:
