The New Jersey Poison Control Center issued a warning about wild, poisonous mushrooms that are growing in the state.

Recent heavy rains have caused more of these mushrooms to come to the surface and officials say they could pose a danger if they are ingested.

“The mushrooms you buy in supermarkets are not toxic but something that is out in the wild could very well be very toxic and cause something like liver failure,” says Poison Control medical director Dr. Diane Calello.

Dr. Calello says that there have been 45 cases of wild mushroom poisoning reported to the center since the beginning of July - 38 human cases and seven animal.

“We will walk you through -- what did that mushroom look like? If you can grab a sample or the rest of that mushroom it will help identifying if it’s a toxic mushroom,” she says.

The patients affected by the poisonings range in age from 9 months to 70 years old. Official say that 13 of the cases ended up in emergency room visits.

Dr. Calello says that a parent should remove mushrooms from their yard if they have young children or pets that are prone to chewing on things.
