Hong Kong/Seoul (CNN) — Three varieties of "fire chicken" instant ramen noodles popularized by a viral internet challenge have been recalled in Denmark after they were deemed to be too spicy. The level of capsaicin found in Buldak Hot Chicken Ramen 3x Spicy, Buldak Hot Chicken Ramen 2x Spicy and Hot Chicken Stew was so high that it could poison consumers, the Danish Veterinary and Food Administration said in a statement issued Tuesday. Capsaicin is a spicy, naturally occurring chemical found in chili peppers. South Korean noodle giant Samyang, which developed the ramen, said on Wednesday that the products were not being recalled because of quality issues. It's "because it is so spicy that it could cause problems," a spokesperson told CNN. "This is the first time they've been subject to (a) recall for this reason." The Danish regulator didn't say whether the recall was prompted by a specific incident. It urged consumers to discard the products or return them to where they were purchased.
