How do I pickup multiples of the same item with the same tag?

Hello, I’m very new to C#. I know the answer to this question may be obvious for most, but I’m stuck at the moment.

I wrote a “PlayerHealth/Damage Script”. So far, it just has one type of damage, and 4 types of health items. (items are tagged)
When I place one of each item in a row, everything works as expected.
(Player picks up health OnTriggerEnter, & item destroys itself etc)

The problem is, when I place multiple “copy’s” of the Prefab throughout the scene, they basically “don’t match up”. (ex. entering a trigger of one item (ex. bread) could Destroy a different copy of the same item (ex. bread(2)) and so on.

Here is my Script:
using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;
public class PlayerDamageScript : MonoBehaviour {

int playerHealth = 100;		
int damage = 10;

public AudioClip bite;
public AudioClip drink;
public AudioClip belch;
public AudioClip ouch;
public AudioClip dead;

void Start () 
{
	print (playerHealth);
	playerHealth = 100;
}

void Update()
{
	if (playerHealth <= 0) 
	{
		Death ();
	}

	if (playerHealth >= 100)
	{
		playerHealth = 100;
		if (playerHealth > 100) 
		{
			GetComponent<AudioSource> ().clip = belch;
			GetComponent<AudioSource> ().Play ();
		}
	}
}
	
//PLAYER HEALTH/DAMAGE TRIGGERS// 
//*****************************//

void OnTriggerEnter(Collider other)
{
	if (other.gameObject.tag == "Enemy")
	{
		playerHealth -= damage; 
		print ("Enemy Hit You!" + playerHealth) ;

		GetComponent<AudioSource> ().clip = ouch;
		GetComponent<AudioSource> ().Play ();
	}

	if (other.gameObject.tag == "apple") 
	{ 
		playerHealth += 10;
		print ("You ate an Apple + 10 Health =" + playerHealth);
		Destroy (GameObject.FindWithTag ("apple"));				

		GetComponent<AudioSource> ().clip = bite;
		GetComponent<AudioSource> ().Play ();
	}

	if (other.gameObject.tag == ("bread"))
	{ 
		playerHealth += 25;
		print ("You ate Bread + 25 Health =" + playerHealth);
		Destroy (GameObject.FindWithTag ("bread"));

		GetComponent<AudioSource> ().clip = bite;
		GetComponent<AudioSource> ().Play ();
	}

	if (other.gameObject.tag == "cheese") 
	{ 
		playerHealth += 50;
		print ("You ate Cheese + 50 Health =" + playerHealth);
		Destroy (GameObject.FindWithTag ("cheese"));

		GetComponent<AudioSource> ().clip = bite;
		GetComponent<AudioSource> ().Play ();
	}

	if (other.gameObject.tag == "potion") 
	{ 
		playerHealth += 100;
		print ("You drank a healing Potion + 100 Health =" + playerHealth);
		Destroy (GameObject.FindWithTag ("potion"));

		GetComponent<AudioSource> ().clip = drink;
		GetComponent<AudioSource> ().Play ();
	}

}

public void Death()
{
	SceneManager.LoadScene (8);
}

}

So, how do I make multiple copy’s of a prefab and pick up each one (correctly) by tag?

Any help would be greatly appreciated! Thanks!

GameObject.FindGameObjectWithTag() searches the WHOLE scene for a GameObject with a given tag. The first GameObject found is returned.

using other.gameObject you get the GameObject of other

Change the lines 54 , 64, 75, and 86 to be Destroy (other.gameObject);
