BERLIN, Oct. 11 (Xinhua) -- The newspaper "Sueddeutsche Zeitung" (SZ) reported on Tuesday German authorities are allegedly attempting to hide the full extent of the Fipronil scandal from the public.

According to the German newspaper, the poisonous insecticide Fipronil has been found in high concentrations in several other products which contained eggs such as pastries and liquor.

A preliminary analysis by the Federal Ministry of Agriculture cited by SZ found that 20 percent of products tested contained traces of Fipronil of which every fourth measured in excess of regulatory limits.

Experts quoted by in the report described the numbers as "remarkable". An unnamed employee in an officially-approved laboratory further complained to SZ that pressure had been exerted on his institution to only carry out superficial tests which failed to provide the public with adequate information about their food safety.

The anonymous source accused the German government of creating a "Consumer Non-Information" system to shield producers from costly recalls. While some products had been removed from supermarket shelves voluntarily, nothing was being done to seize products purchased by consumers before the Fipronil scandal was revealed.

The situation has led to a spat between the federal and regional levels of German government. The heavily-affected state of Lower Saxony on the Dutch border, in particular, has urged Berlin to prioritize consumer safety and shift towards a tougher "zero tolerance" policy on Fipronil-contaminated products.
