hey;
i dont see any problems in your script or the objects;

can u show me a screen shot from your snake object too ;

Both gameobjects must have a collider, one of them must be trigger and also any of them must have attached a Rigidbody.
Also keep in mind if it is OnTriggerEnter or OnTriggerEnter2D
