The U.S. consumer safety watchdog urged parents on Tuesday to closely inspect their children's cribs for proper safety features after a massive product recall was issued.

New York-based Delta Enterprises recalled nearly 1.6 million cribs on Monday over problems with the cribs' drop-side function after two children died.  

There are  no details about how the two children died.

Canadians who purchased cribs in the U.S. should take note of the recall, but otherwise the cribs were not sold in Canada:

• Health Canada said it has confirmed the cribs were not sold in Canada. 
• Delta Enterprises told CTV News it did not sell the cribs covered by this latest recall to Canadian outlets.
• Wal-Mart, Sears and Toys "R" Us also reported they never sold the cribs in Canada.

The cribs included in the recall were made in China, Indonesia and Taiwan.

The recall is among the largest in U.S. history and comes on the heels of last week's recall of 2,000 China-made cribs issued by the Consumer Product Safety Commission.

The Monday recall was for Delta cribs produced between 1995 and 2007 that use a drop side trigger lock design.

Cribs that don't use the trigger lock release are not affected.

For those that do, owners are asked to determine what type of pegs their crib uses, and whether all the pegs are in place.

If pegs are missing, owners are asked to stop using the crib immediately and fill out an online form. Delta will then mail out replacement pegs.

"Even if you have safety pegs in place, please fill in this form and we will send you a set of new colored pegs to replace your existing pegs. The new color will make it easier for you to ensure that the pegs are always in place," the website states.

Owners of cribs that were manufactured in China prior to 2006 should cease using the product and fill out the online form so that a retrofit kit will be mailed out at no cost.

After the recall was issued, China's foreign ministry spokesperson told a news conference that China -- which is still dealing with a tainted-milk scandal that sickened thousands of children -- is focused on safety.

"I can say the Chinese government takes product safety very seriously, especially when it comes to children's products," he said.

One year ago, consumer confidence in Chinese-made products was seriously shaken by a massive recall of Chinese toys tainted with lead and sold by Mattel Inc.

The U.S. Consumer Product Safety Commission issued the following safety tips for all parents who use cribs:

• Parents should not use any crib with missing, broken or loose parts.
• Hardware should be inspected from time to time and tightened to keep the crib sturdy.
• When using a drop side crib parents should check to make sure the drop side or any other moving part operates smoothly on its track.
• Always check all sides and corners of the crib for disengagement. Any disengagement can create a gap and entrap a child.
• Do not try to repair any side of the crib without manufacturer approved hardware or with tape, wire or rope.
• Putting a broken side up against the wall does not solve the problem and can often make it worse.
