The tainted eggs account for only a small amount of overall EU production, Attila Nagy, the deputy director of NÉBIHʼs Food and Feed Safety Directorate, told state news channel M1.

Hungaryʼs egg farmers could profit from the contamination scandal as no local eggs were affected, he added.

Eggs contaminated with an insecticide dangerous to humans were discovered in 15 EU countries and two countries outside of the EU by Friday last week. The countries include Austria, Belgium, Denmark, France, the Netherlands, Ireland, Poland, Luxembourg, the U.K., Germany, Italy, Romania, Sweden, Slovakia, Slovenia, Switzerland and Hong Kong.

A carton of ten eggs sold for an average HUF 367 in Hungary in July, the latest data from the Central Statistical Office (KSH) show, according to state news wire MTI.

According to a report on bbc.com, eggs coming mainly from the Netherlands have been found to contain fipronil, a substance used to kill lice and ticks on animals that is banned by the EU for use in the food industry. It is thought it was used to combat lice in some chicken farms, affecting the eggs of laying hens.

Farms were shut down in the Netherlands, Belgium, Germany and France after authorities confirmed that fipronil had been used.
