"We have identified that a very small number of eggs have been distributed to the United Kingdom from the farms affected", said an FSA spokesman.
A statement from FSA said: "Following concerns raised in the Netherlands about a substance called Fipronil which has been used inappropriately in cleaning products on chicken farms, we have identified that a very small number of eggs have been distributed to the United Kingdom from the farms affected".
But it says this is a very small proportion of the 1.8 billion eggs the United Kingdom imports each year.
Millions of eggs have been removed from shelves across the continent over fears they could be deadly.
Anna-Kaisa Itkonen, a European Commission spokeswoman, said, "We do not know if the eggs are contaminated or not, but because of these notifications, it's now up to the national authorities to check".
In large quantities, the insecticide is considered to be "moderately hazardous" according to the World Health Organization, and can have risky effects on people's kidneys, liver and thyroid glands.

Mosque Blast in Afghanistan Kills 20 People
In recent months, Daesh has been making inroads in Afghanistan through alliances with local militant outfits. Officials fear the death toll could rise since 10 of the wounded are in critical condition, said Dr.
The country's agriculture minister said he had ordered its food safety agency to make clear why it failed to notify neighbouring countries until 20 July, despite knowing about the contamination since June.
Millions of eggs have been pulled from supermarkets in Germany and the Netherlands in a widening scandal over possible contamination by the insecticide fipronil that has triggered investigations by prosecutors in Belgium and the Netherlands, and the temporary shutdown of some poultry farms.
Dutch investigators believe the insecticide was illegitimately used in a cleaning product to treat red mite in poultry houses.
Dutch authorities have shuttered 138 poultry farms - about a fifth of those across the country - and warned that eggs from another 59 farms contained high enough levels of fipronil that they should not be eaten by children.
EurActiv reports that manufactured by Germany's BASF among other companies, fipronil is commonly used in veterinary products to get rid of fleas, lice and ticks.
European Union bodies immediately notified food safety authorities in Britain, France, Sweden and Switzerland after it emerged that eggs contaminated with the insecticide may have entered their territories.
