Some of this year's treats may be on a recent recall list.
"Raisenettes, for example, have undeclared peanuts in some packages," said Don Mays of Consumer Reports. "Kids with peanut allergies could have very severe reactions so that can be very dangerous."
Also, some Mega Pops brand lollipops may contain traces of metal, so the maker has recalled certain bags.
However, Mays said, the biggest risk to kids on Halloween is not from candy.
"The number of child pedestrian deaths during Halloween night is four times higher than any other night of the year," he said.
