Can Spanish rice cause my sons poop to turn reddish?

Tamara • Mommy to my 2 beautiful baby boys, Nathan Louis💙 born August 12, 2017 and Parker Joseph May 6, 2019❤️ My whole world😍

He had Spanish rice the other night and yesterday he was having reddish orangish poop. Is this normal? I’m just worried if it’s blood in his poop? Been feeding him dairy lately(he had reflux ever since he was born which dairy was the reason for it) I think it’s away, been feeding him it for a week now and just saw the reddish orange poop yesterday
