Check loaded category id is exist or not

<?php $categories = $_product->getCategoryIds(); ?>
  <?php foreach($categories as $k => $_category_id): ?>
<?php $_category= Mage::getModel('catalog/category')->load($_category_id)?>
     <?php if($_category->getId()):?> 
      <a href="<?php echo $_category->getUrl() ?>">
         <?php echo $_category->getName() ?> | </a>
        <?php endif;?>
   <?php endforeach; ?>
