Fipronil origin and measures
Fipronil origin and measuresTimeline
The NVWA website publishes a list of egg codes for contaminated eggs.
Transport is halted at about 180 laying hen farms, breeding farms and egg hatching farms on the suspicion of fipronil use. The NVWA has taken samples of eggs, and in some cases manure and chicken meat, from all sheds on all of these farms. It has also sampled eggs from within the retail sector. The initial results of the egg samples lead the NVWA to issue a public warning.
As a precaution, the NVWA is halting transport at other poultry farms which underwent treatment by the poultry service company this year.
The Public Prosecution Service supplies the NVWA with address details of the poultry farms involved.
The lab results of seven Dutch laying hen farms are positive for fipronil use. As an immediate consequence, the NVWA is halting transport at these seven laying hen farms. These poultry farms are not allowed to transport eggs, laying hens or manure, and are also required to remove their eggs from sale.
The Public Prosecution Service supplies the NVWA with data from the confiscated records. Samples of eggs and manure are taken at eight Dutch farms, with one additional business to be sampled on 20 July.
The poultry service company is inspected, but fipronil is not found. The NVWA takes various samples.
The Belgian authorities formally request the NVWA to conduct an investigation into the Dutch pest control company. Preparations for the investigation into the poultry service company commence.
Fipronil is found in eggs at a Belgian laying hen farm. This finding is linked to a poultry service company administering treatment for red poultry mite. It is suspected that the treatment involved the use of fipronil, a prohibited substance.
