Passengers are still forgetting to empty potentially dangerous items from their hand luggage before travelling.
Siobhan Moore of the Dublin Airport Authority (DAA) told the Herald: "We are noticing an increase in people carrying sharp objects in their hand luggage.
"If an item is prohibited, it has to be surrendered. Also, it does slow up the screening process without a doubt, if even three or four people in a line have to have their bag searched in more detail."
Siobhan said: "This year to date we have over 1,000 kilos of items that had to be surrendered because they don't conform to the rules and regulations. These regulations are set down by the EU."
The top four things that are seized are sporting bats, like hurley sticks, knives, such as kitchen sets, toy guns and toy handcuffs, she said.
"We have a company that takes these items away and disposes of them in an environmentally safe manner," she said.
Among the banned items are any objects with a sharp point or sharp edge capable of being used to cause serious injury, which includes razor blades, box cutters, knives with blades of more than 6cm, and scissors with blades of more than 6cm.
Meanwhile, EU aviation security regulations prohibit all passengers from carrying any liquid, gels or pastes of more than 100mls through security screening, but passengers can sometimes also forget about this requirement.
Siobhan said that items such as wine or gift sets are donated to charity. "Hampers are made up and used for draws to raise money for charity at various fundraising events," she said.
This year, DAA staff are supporting Bee for Battens, Make a Wish Foundation and Down Syndrome Ireland charities.
