U.S. and Hong Kong health authorities issued recalls Friday for more products, including coffee and baby cereals, because they may be contaminated with the industrial compound melamine.

The U.S. Food and Drug Administration said it was recalling Mr. Brown instant coffee and milk tea products manufactured by Shandong Duqing Inc. in China.

The U.S. recall affects the following products:

• Mr. Brown Mandheling Blend Instant Coffee (3-in-1).
• Mr. Brown Arabica Instant Coffee (3-in-1).
• Mr. Brown Blue Mountain Blend Instant Coffee (3-in-1).
• Mr. Brown Caramel Macchiato Instant Coffee (3-in-1).
• Mr. Brown French Vanilla Instant Coffee (3-in-1).
• Mr. Brown Mandhling Blend instant Coffee (2-in-1).
• Mr. Brown Milk Tea (3-in-1).

Separately, the Hong Kong government said it was recalling contaminated Heinz-brand baby cereals and Silang House steamed potato wasabi crackers. Garfield Balsom, a spokesman for the Canadian Food Inspection Agency, said the Heinz cereals are not imported into Canada.

Earlier this month, melamine — a compound used in fertilizers and resins — was detected in milk products sold in China. More than 50,000 infants and children have been sickened and four children have died after consuming tainted products.

Health authorities say consuming small amounts of melamine does not pose a significant safety hazard, but for children and in larger doses the chemical can cause kidney stones and lead to kidney failure.

In 2007, FDA officials speculated melamine was added to wheat gluten and rice protein used for pet food because it falsely appeared to raise the protein content of the ingredients.
