Question

Poisonous substances created by plants (poison ivy), animals (rattlesnakes), or improperly prepared or stored food

I think the second letter is I and made up of 6 words

Answer 1

I think the word is TOXINS! Poison ivy makes a very toxic oil called urushiol, rattlesnakes make hemotoxins and neurotoxins, and improperly made or stored food can harbor bacteria that release toxins causing food poisoning symptoms.
