Flushing dog or cat waste down the toilet may seem harmless, but veterinarians are warning of serious risks to both public health and sewage systems. Around 3–6% of pet owners admit to doing it, thinking they’re doing the right thing—but experts say they’re playing with fire.

Toxocara: The Tiny Parasite with Big Problems

The main concern? Toxocara—a roundworm parasite commonly found in pet feces. A viral TikTok video by vet ‘Ben the Vet’ emphasizes that Toxocara worm eggs:

• Survive high temperatures in water treatment plants
• Remain resilient and infectious, entering waterways despite processing

Left unchecked, these eggs can lead to:

• Visceral larva migrans—larvae migrating through organs
• Ocular larva migrans—larvae damaging the retina, possibly causing blindness
• Links to lower IQ and developmental delays in infected children

Dr Alice Judge of Pet Impact stresses toxocara often endures sewage conditions, and that flushing cat litter carries similar risks.

Plumbing Nightmares: Beyond Pet Health

It’s not just the parasites—flushing pet waste, even “flushable” bags, wreaks havoc on plumbing systems. “Poo bags do not break down,” reports Anglian Water, attributing 40,000 blockages a year to improper disposal.
Dr Alice Judge confirms biodegradable litter still doesn’t dissolve in toilets, leading to clogged pipes, burst sewers, and flooded homes .

Children at Greatest Risk

Young children are particularly vulnerable to Toxocara infection. With lower immunity and frequent outdoor play, they come into contact with contaminated soil much more often. Even airborne eggs around toilet areas could be risky .

Vet Advice: Simple, Effective Precautions

1. Bag pet waste promptly and dispose of it in bin bins—not the toilet.
2. Worm your pets regularly, ideally every 12 weeks, to prevent Toxocara eggs being expelled.
3. Wear gloves and wash hands after handling feces or used waste bags.
4. Avoid contact with pet mess in garden—children especially should stay clear of uncleaned spots.

Sewer Systems Matter: It’s a Shared Responsibility

Local water providers advise putting clear signage in public parks and communal waste bins to remind owners not to flush. They also share stories of costly public blockages—sometimes running into tens of thousands of pounds per incident.

Final Word: A Small Change, Big Impact

Whether you’re cleaning up in your flat or at the beach, remember: dog poop can’t go down the toilet. That simple change can help prevent:

• Public health risks (parasitic worms, blindness, developmental harm)
• Significant drain and sewer damage
• Out-of-pocket and public expenses

What You Can Do Right Now

• Always bag your pet’s poop and place it securely in your bin.
• Encourage responsible habits among fellow pet owners.
• Advocate for local warning signs in parks and communal bins.
