The fruit is dried, candied and still sealed, so it should last at least two years, provided it was stored away from heat.
u can eat it. theres no wurrys .
I always seems to have some left over from the year before and I use it. I make fruit cake muffins from it every Christmas and every body loved them and lived.
The fact that yours is still sealed is a bonus. Taste it and make sure. I think it will be fine.
