Rise in reports of toxic blue green algae
Blue green algae blooms appear as green or greenish-brown scum on the surface of water.

BVA issues warning after affected water bodies confirmed 

A rise in reports of toxic blue green algae in several locations across the UK has prompted the BVA to issue a warning to pet owners.

So far this summer, blue green algae has been confirmed in water bodies in Southampton and Fleet in Hampshire, Edinburgh and Elgin in Scotland, Cornwall, Leicestershire, Derbyshire and Lincolnshire, among other locations.

Meanwhile, three dogs in North Carolina died this week, just hours after swimming in an affected pond.

BVA’s junior vice president Daniella Dos Santos said: “We know that some dogs enjoy nothing better than a paddle in a cool lake while on a walk during summer months, but my advice to pet owners would be to keep your dog on a lead during walks near water confirmed to have toxic algal blooms.

"While not all blue green algae are poisonous, it is impossible to tell the difference visually, so it is better to be safe than sorry.

“There is currently no known antidote for the toxins, so prompt veterinary treatment is essential to tackle their effects and ensure a good chance of recovery. If you suspect your dog has been exposed to blue green algae, rush it to your local vet without delay."

Blue green algae blooms appear as green or greenish-brown scum on the surface of water and can contain toxins that are harmful to animals, even in small quantities. Dogs swallow the algae by drinking the water or licking their fur after a swim.

Symptoms appear within a few minutes or hours of exposure and can include vomiting, diarrhoea, drooling, disorientation, difficulty breathing, seizures and blood in the faeces. Left untreated it can cause liver damage and rapid death.

BVA’s advice to pet owners:

  • look out for any warning signs put up by the Environment Agency or local councils near water bodies
  • keep pets on a lead and by your side around water bodies known or suspected to have blue-green algal bloom – don’t let them swim in it or drink from it
  • if your dog has been swimming outside, wash it thoroughly with clean water afterwards
  • rush your pet to a vet immediately in case you’re concerned it may have ingested toxic algae.

Bluetongue reaches Wales for first time in 2025

The Animal and Plant Health Agency (APHA) has revealed that bluetongue has been confirmed in Wales for the first time in 2025.

In their latest statistics, APHA records a total of 109 cases of BTV-3 or BTV-8 in Great Britain in the 2025-2026 vector season.

The total number of BTV-3 cases in Great Britain this season is 107. This includes 103 cases within the England restricted zone and four cases in Wales.

There has also been two cases of BTV-8, which were both in Cornwall.

As a result of the cases in Wales, a Temporary Control Zone (TCZ) is enforced in Monmouthshire. Animals can move freely under general license within the England Restricted Zone, however animals with suspected bluetongue must stay on their holding.

All premises testing positive for blue tongue can be viewed on this map.
