Most agricultural products go through screening to remove unwanted materials, but these systems can miss items that closely resemble the food in size and appearance. For example, I once bit into a rock that looked exactly like an almond in a bag of almonds. While it’s a rare occurrence, it’s still important to stay cautious. If something like this happens, contact the company and provide the product’s serial or lot number. This helps them trace where and when it was packaged and check if there was a problem with the screening process.
