Biosecurity, Hygiene & Safety

"Biosecurity" is a big word for a simple idea: stopping germs from spreading. In a place where lots of people meet lots of animals, tiny germs can travel from animal to animal, or from an animal to a person, without anyone noticing.

What we're protecting against

• Animal to animal — one poorly animal can pass germs to the whole collection if we're not careful.
• Animal to person — a few animal germs can make people ill (we'll meet these in module 3).
• Person to animal — we can carry germs in on our hands and shoes too.

Handwashing is the single most important habit in this whole course. Most animal germs are passed on hands, so clean hands stop most problems before they start.

When to wash

• Before handling any animal.
• After handling any animal.
• After cleaning enclosures, equipment or spills.
• Before eating, drinking or touching your face.

How to wash properly

1. Wet hands with warm water and add soap.
2. Rub palms, backs of hands, between fingers, thumbs and nails for a full 20 seconds (about singing "Happy Birthday" twice).
3. Rinse well and dry with a clean paper towel.

A "zoonotic" disease is one that can pass from animals to people. This sounds scary, but the good news is that simple hygiene stops almost all of them. Here are the common ones to know about.

The main ones

• Salmonella — often carried by reptiles and amphibians (like lizards, snakes and frogs), even when they look perfectly healthy. It causes a nasty tummy upset. Always wash hands after handling them.
• Psittacosis — a chest infection linked to birds, especially parrots. Good ventilation and clean cages help prevent it.
• Ringworm — not a worm at all, but a fungal skin infection that can pass from animals (and people) by touch. It causes a round, itchy patch.
• General gut bugs — E. coli, campylobacter and similar germs live in animal droppings and cause tummy upsets.

Who is most at risk

• Young children (they touch everything and then their faces).
• Pregnant people.
• Anyone unwell or with a weaker immune system.

Cleaning and disinfecting are two different jobs, and the order matters. Clean first, then disinfect. You can't disinfect dirt.

1. Clean — remove visible mess, droppings and bedding with detergent and water.
2. Disinfect — apply an animal-safe disinfectant to kill the germs the cleaning left behind.
3. Wait — leave the disinfectant on for its contact time (the time on the label, often several minutes) so it actually works.
4. Rinse and dry as the product directs before the animal returns.

Colour-coded equipment

• Use colour-coded cloths, buckets and brushes so kit for one job or one animal isn't used for another.
• Clean between different animals and their enclosures to stop germs hitching a ride.
• Only use products that are safe for the species — some cleaners are toxic to reptiles, birds and small pets.

Taking animals out to schools, care homes and events means moving them safely and kindly. A stressed or too-hot animal is an unwell animal.

• Secure carriers — every animal travels in a proper, escape-proof carrier that is fastened in the vehicle.
• Right temperature — not too hot, not too cold; many of our animals need gentle warmth, but a hot car is deadly.
• Ventilation — make sure fresh air can move through the carrier.
• Minimise stress — keep it dark, quiet and steady; avoid loud music and sharp braking.
• Short trips — plan the shortest sensible journey and settle animals quickly at the other end.

When a new animal joins us — or an animal seems poorly — we keep it apart for a while. This is called quarantine, and it protects the rest of the collection.

• Isolate new or sick animals away from the others in a separate space.
• Separate equipment — use its own bowls, cleaning kit and tools, and always deal with quarantined animals last.
• Observation period — watch it closely for a set time (often a couple of weeks) for any signs of illness before it joins the group.
• Extra hygiene — wash hands and change gloves/aprons between the quarantine area and everywhere else.

Sometimes an animal wriggles free — it happens even to careful handlers. Preventing escapes is best, but knowing how to respond calmly matters just as much.

Prevention

• Secure enclosures — check catches, lids and locks every time.
• Double-door checks — make sure one door is shut before another opens where possible.
• Handle small or fast animals low down and over a contained space.

If an animal escapes during a session

1. Stay calm — a calm handler keeps the animal and the group calm.
2. Keep the group still and quiet so the animal isn't chased or frightened.
3. Close doors and windows to contain the room.
4. Recapture gently and slowly, never grabbing.
5. Do a head-count afterwards to be sure every animal is accounted for, and review what happened.

A risk assessment is simply thinking ahead: spotting what could go wrong before it does, and putting sensible steps in place. We do one for every session or visit.

The simple steps

1. Spot the hazards — what could cause harm? (A scratch, a germ, a trip, an escape.)
2. Who might be harmed? — visitors, staff, children, the animals.
3. Control measures — simple steps to reduce the risk (handwashing stations, supervision, secure carriers, calm handling).
4. Review — check it still works and update it after each session.

PPE means "personal protective equipment" — the simple kit that keeps you safe while you work with animals and clean up.

• Gloves — wear disposable gloves for cleaning, handling droppings, or dealing with a poorly animal.
• Aprons — protect clothing during cleaning and messy jobs.
• Cover cuts — put a waterproof plaster over any broken skin before handling animals.
• No eating or drinking around the animals or their enclosures — germs travel on food and hands.

Tick off each step as you make it a habit. Your progress saves automatically.

• Wash hands before handling any animal
• Wash hands after handling any animal
• Wash hands after cleaning, and before eating or drinking
• Wash for a full 20 seconds, then dry with a clean paper towel
• Supervise children washing their hands
• Keep hand gel handy as a backup only
• Clean enclosures first, then disinfect
• Leave disinfectant on for its full contact time
• Use colour-coded cloths, buckets and brushes
• Clean equipment between different animals
• Wear gloves and an apron for messy jobs; cover any cuts
• No eating or drinking around the animals
