Eggs shouldn't need to be washed

We are often asked if our eggs are washed. The answer is NO. There is no need for eggs to be washed on a properly managed farm.If nest boxes and sheds are clean, and there is no build-up of mud and manure around sheds, the eggs will be clean.

This pesticide is used as a:

  • VIRUCIDE and is commonly found on the shells of most eggs – even from organic farms.
