5 of the most toxic berries found in the UK

Through this piece we’re going to be taking a look at the 5 of the most toxic berries found in the UK (or at least from our experience foraging over the years).

In summer and autumn time the hedgerows and woods of the UK really come alive with colour, and berries of almost every conceivable colour appear, but how do you know which ones are good to eat and which to avoid?

As a child we’re told that red is a natures warning sign, but what about strawberries or raspberries? These are bright red or pink, fully edible and taste delightful. Unfortunately, there are no general rules in foraging and we always have to look a little deeper into the edibility of each of the items we find.

Most of us are quite familiar with blackberries and raspberries which are delicious, but here are some berries that you would definitely want to avoid.

Let’s take a closer look at 5 of the most toxic berries found in the UK

Yew (Taxus baccata)

A large evergreen tree, most often found in parks, churches and graveyards. Virtually all parts are deadly toxic. Just a small quantity of the leaves or seeds would be enough to kill a human. The only edible part is the flesh around the seeds.

What Can Black Bryony be Confused with?

It could be confused with the Guelder rose but Guelder berries grow on umbels and Bryony berries grow on racemes.

Lords and Ladies (Arum maculatum)

All parts of the plant contain oxalate crystals, but they are more concentrated in the berries. The plant tastes foul and contact causes an almost immediate burning sensation so you’re unlikely to eat enough for it to kill you thankfully. It does cause skin irritation and swelling and in theory it could cause your airways to become inflamed making it difficult to breath. There are no recently recorded fatalities from Lords and Ladies.

They have apparently been confused with Bilberries (Vaccinium myrtillus) in the past. But Bilberries normally appear earlier in the year, have a ‘bloom’ on the surface and the plants themselves look very different.
