Sour grapes? Nope, just a snake in the box

Two news reports are reporting an adder was found in a box of grapes imported to the UK from Spain, but some information just doesn't add up. From the BBC (the Yahoo article just takes excerpts from the BBC article):

The 10" long adder was found during a quality check by a worker at Orchard County Foods in Craigavon. The grapes were imported from Spain. The staff member did not panic and raised the alarm with management. The USPCA was called to the scene and took the snake away to a specialist reptile shop in Belfast. .... Wayne said the reptile is poisonous and dangerous to anyone who is allergic the bee stings. He added: "You can tell that it is some sort of adder because of the shape of its head. It turns into a diamond shape when it gets annoyed. This is because it has venomous glands on either side."

Dr. Bryan Greig Fry posted this to his Facebook page, and a lively discussion ensued. One of his friends ID'd it probably more correctly as a Natrix Maura or perhaps, as Fry says, a Natrix tessellata. But it is most definately a Natrix. You decide; the grainy lead photo is from the news article, but after the bump, photos of the other two more probable species.
