What is Toxocariasis?

The human infection (toxocariasis) is rare and is caused by roundworm parasites. It usually affects young children.This is because children are more likely to come into contact with contaminated soil when they play and put their hands in their mouths. However, cases have been reported in people of all ages. Toxocariasis may occur if mature Toxocara (roundworm) eggs are swallowed, however, it is very rare for anyone to become ill as a result. About 1-2% of healthy adults in the UK already possess Toxocara antibodies which means that they have been exposed to Toxocara eggs or larvae with no ill effects.

On the rare occasions when human disease does occur, it usually causes only mild symptoms. In exceptional cases it can cause damage to the eye in young children this is called ocular toxocariasis. The chances of developing toxocariasis are low. It is estimated that there are only about two new cases of disease due to Toxocara infection per million of the population each year. A study on toxocariasis in school children in Ireland found that of 121,156 pupils surveyed eleven ocular toxocariasis cases were identified. The estimated number of definite cases of ocular toxocariasis was 6.6 cases per 100,000 persons. When ophthalmologists on Merseyside whose hospital practices served a population of about 200,000 children were asked about cases of ocular toxocariasis they could only recall 3 cases of ocular toxocariasis between them in the previous 20 years. 

Advice to Pet Owners

  • Parents and children should be aware of the dangers associated with puppies, kittens and older dogs and cats.
  • Many puppies are infested with the roundworm parasites from birth, as a pregnant dog can pass the parasites to her puppies before they're born.
  • All dogs and cats require regular de-worming with anti-worm medicine. See your vet for regular check-ups and for specific advice on how to treat your pet.
  • The parasite eggs responsible for toxocariasis can survive for many months in sand or soil, so all pet faeces should be collected anddisposed of immediately.

Roundworm parasites are most commonly found in cats, dogs and foxes. The worms may cause sickness and diarrhoea in young animals. Adult dogs generally show no signs of ill health but still need regular worming. 

If every owner treated their dog with a worming preparation, and cleared up after their dog, toxocariasis would be virtually eradicated. The eggs only become infectious after 10-21 days, so there's no immediate danger from fresh animal faeces. However, once the eggs are passed into sand or soil, they can survive for many months. 


Practising good hygiene can help prevent toxocariasis. Some of the steps you can take are listed below:

  • Wash your hands well with soap and warm water after handling pets or coming into contact with sand or soil.
  • Teach children to always wash their hands after playing with dogs or cats, after playing outdoors and before eating.
  • Wash food that may have come into contact with soil.
  • Try to avoid letting children play in areas where there's a lot of dog or cat faeces.
  • Teach children that it's dangerous to eat dirt or soil.

The eggs only become infectious after 10-21 days, so there's no immediate danger from fresh animal faeces. However, once the eggs are passed into sand or soil, they can survive for many months.

Tick Warning

There has been an increase in the number of ticks found on pets possibly due to warm and damp weather.

  • Ticks carrying disease are found across the UK
  • They can be very small and bites can be unnoticed
  • Ticks are most active from March to October, but they can be active on mild winter days
  • You will not feel the tick attach to you, so check your skin and that of children
  • The tick must be removed as soon as possible after it attaches and without squashing it. If you are not sure of how to remove a tick seek advice from a vet.

 Ticks feed on the blood of other animals. If a larval tick picks up an infection from a small animal, when it next feeds as a nymph it can pass the infection to the next animal or human it bites.

 They cannot jump or fly, but when ready for a meal will climb a nearby piece of vegetation and wait for a passing animal or human to catch their hooked front legs. The tick will not necessarily bite immediately, but will often spend some time finding a suitable site on the skin, so it is important to brush off pets and clothing before going inside.”

Once a tick has started to feed, its body will become filled with blood. Adult females can swell to many times their original size. As their blood sacs fill they generally become lighter in colour and can reach the size of a small pea, generally grey in colour. Larvae, nymphs and adult males do not swell as much as they feed, so the size of the tick is not a reliable guide to the risk of infection. If undisturbed, a tick will feed for around 5 to 7 days before letting go and dropping off.

The bite is usually painless and most people will only know they have been bitten if they happen to see a feeding tick attached to them.

The risk of infection increases the longer the tick is attached, but can happen at any time during feeding. As tick bites are often unnoticed, it may be difficult to determine how long it has been attached. Any tick bite should be considered as posing a risk of infection.

Dog Fouling

Street Scene Officers from Fenland District Council were invited to Alderman Jacobs School to speak to their assembly about the small minority of irresponsible dog owners who fail to clear up after their dogs, this followed on from upset and annoyed parents who contacted both FDC and the school regarding their children who, while walking to and from school, were having to dodge the dog mess left behind and some had got this on their shoes and were carrying it into school and home.

The students were invited to  get involved in a poster completion which will be judged and the winning poster will be displayed around Whittlesey in the next coming week, this is one way Fenland District Council is getting the community on board to help tackle  this issue and hopefully these posters will prick the conscience of the few dog owners who refuse to take responsibility for their dogs.

Look out for these posters which are displayed around Whittlesey !
