No. It is forbidden in the Netherlands under the Nature Protection Act. It also carries serious health risks (such as seal finger) and causes heavy stress for the animal. Always keep at least 30 metres distance.

Is petting punishable?

Yes. Seals are protected species under the Dutch Nature Protection Act (Wnb). Touching, deliberately disturbing or catching them can be punished with fines up to thousands of euros and, for serious violations, imprisonment.

Seal finger is a serious infection of the hand, usually caused by Mycoplasma bacteria from a seal's mouth. Without quick treatment with tetracycline antibiotics, it causes swelling, joint stiffness and permanent damage to fingers and hand.

What other diseases can you catch?

Besides Mycoplasma, seals can also transmit brucellosis, influenza, parapox and parasites to humans. Some of these infections are rare but serious, especially for people with a weakened immune system.

Can you pet a seal?

Q: What should you do instead?

Keep at least 30 metres distance, use binoculars, keep dogs on the leash and call a seal warden if the animal appears in distress. Only trained wardens may intervene.

Straight to the point: NO

It is tempting. A seal on the beach looks at you with large, dark eyes; the coat looks warm; the nose is round and cute. Many people think a quick pet "does no harm". It does. And it is also punishable. We line up the three reasons.

Reason 1: the law

Seals are strictly protected in the Netherlands under the Nature Protection Act (Wnb), which replaced the old Flora and Fauna Act in 2017. Article 3.5 prohibits, among other things:

Deliberately killing, catching or disturbing protected species.
Damaging or destroying their breeding or resting sites.

"Disturbance" is interpreted broadly: deliberately approaching a resting animal, touching it, or removing a pup from a beach all fall under it. Violations can lead to fines up to several thousand euros, and in serious cases to criminal prosecution. In the Wadden region, additional regulations apply that prohibit entering resting sites.

Since the Seal Agreement (2020), bystanders may also no longer simply pick up or move a pup — only government-recognised seal wardens may intervene.

Reason 2: health (the "seal finger")

Seals carry bacteria in their mouths and on their skin that cause severe infections in humans. The best known is "seal finger": a local, very painful inflammation, usually caused by Mycoplasma bacteria. An untreated seal finger can develop in days into a chronic joint inflammation with permanent loss of function. Until 1900, whalers often had a finger joint amputated to stop the infection — antibiotics didn't exist yet. Today only specific antibiotics (such as tetracycline) work against it; standard penicillins have no effect.

Seals also carry other pathogens that can rarely jump to humans:

Brucella pinnipedialis — a bacterium that affects seal joints and organs; in humans it causes brucellosis, a serious febrile illness.
Influenza A — seal flu, particularly H10 strains that occasionally jump to humans.
Parapox and seal pox — cause blister formation on skin contact.
Salmonella, Leptospira and various parasites — transmitted via faeces or saliva.

An infection doesn't require a bite. Touching a sick seal with a small open wound or scratch on your finger can be enough.

Reason 3: welfare (severe stress)

Perhaps the most important reason, and certainly the least visible: human contact causes extreme stress. Wild seals are shy predators. They see us as predators. A human within 30 metres doubles their heart rate; touching pushes it to 200 beats per minute, and stress hormones stay elevated for hours afterwards.

For a pup this is catastrophic. A mother who has left her pup to forage recognises it by smell — if it smells of hand cream, perfume or human sweat, she may reject it. For weakened pups, stress also directly costs energy they no longer have.

What should you do instead?

Keep 30 metres distance from a resting seal, and 50 metres from a pup.
Use binoculars or a telephoto lens to look without approaching.
Keep dogs on the leash — for the seal and your dog, who otherwise risks a dangerous bite.
Call a warden if the animal appears in distress — via the national seal line. See our seal pup protocol.
Never feed them: especially not bread or fish from your own fridge.
