If your daughter ate a frozen mushroom straight out of the freezer, it is difficult to determine the potential consequences without knowing the specific type of mushroom and her individual health conditions or allergies. Some mushrooms can be toxic and cause gastrointestinal distress or more severe reactions.
In this situation, it is crucial to seek immediate medical attention. Contact your local poison control center or take your daughter to the nearest emergency room as soon as possible. The medical professionals there can assess the situation, provide appropriate advice, and take any necessary actions to ensure her well-being.
In general, it's essential to keep potentially harmful substances out of reach of children, especially when it comes to unfamiliar or wild mushrooms, as some varieties can be poisonous. Prevention and quick action are crucial when dealing with potential poisoning incidents.
