Officials have also warned of the danger of the transmission of avian flu from animals to humans, which could be deadly. No such cases have been recorded in Israel.
The first signs of the outbreak came about two months ago, according to the Ministry of Environmental Protection, with infections cropping up in chicken and turkey farms in different areas of the country.
Israel’s minister of agriculture and rural development, Oded Forer, said about 600,000 chickens had been culled. He said that would mean a shortfall of 15 million eggs per month over the next few months and that the department was working to import millions of eggs.
In an interview with Kan Radio, Israel’s public broadcaster, on Tuesday, Mr. Forer blamed the outdated, overcrowded chicken coops that he said were common in Israel for the severity of the outbreak of the virus.
The egg industry had been “neglected for years,” he said, adding that most of the coops in Israel were like those from the 1950s or 60s, and that there was a need to move to more modern coops without cages.
