Abstract

A new method for the treatment and disposal of Category 2 animal by-products (ABP’s) of fish origin according to Regulation (EC) 1774/2002 was assessed for the inactivation of the relevant biological hazards. It is proposed that the method will be used for the treatment of Category 2 fish material obtained from aquaculture plants. The proposed process technology consists of grinding fish raw material followed by acidification and heat treatment. The main steps of the proposed process are the mixing with formic acid, the storage for at least 24 hours at
pH < 4, the heat treatment of the fish silage at a temperature ≥85°C for at least 25 minutes. It was concluded that, based on the results of the laboratory experiments, the risk related to pathogens present in fish ABPs from aquaculture would be adequately reduced by the proposed process, if the requirements of the HACCP plan are achieved. However, since there was no validation of the process in an existing plant, it is not possible to conclude on the feasibility of the given HACCP plan. It was further recommended that the full scale equipment should be designed in a way to permit validation by exposure to representative test organisms.

Summary

Following a request from the Norwegian Food Safety Authority, the Panel on Biological Hazards (BIOHAZ) was asked to deliver a scientific opinion on a new method for the treatment and disposal of Category 2 animal by-products of fish origin, related to the inactivation of the relevant microbiological hazards.

According to the applicant, the proposed process technology will be used for the treatment of Category 2 fish material obtained from aquaculture plants. The main steps of this process are the mixing with formic acid to obtain a pH < 4, the storage of the fish silage for at least 24 hours before heat treatment at a temperature ≥85°C for at least 25 minutes.

The BIOHAZ Panel assessed the application following the scheme proposed in the “Guidelines for applications for new alternative methods of disposal or use of animal by-products” prepared jointly by the Health and Consumer Protection Directorate-General (DG SANCO) and EFSA.

The Panel concluded that, based on the results of the laboratory experiments, the risk related to pathogens present in fish ABPs from aquaculture would be adequately reduced by the proposed process, if the requirements of the HACCP plan are achieved. However, since no full scale equipment has been built so far, there was no validation of the process in an existing plant, and it is not possible to conclude on the feasibility of the given HACCP plan. To verify the feasibility of the proposed HACCP plan in a full scale plant, the records of the main parameter (e.g. time, pH, temperature) should be assessed for a certain period under real operating conditions.

Moreover the BIOHAZ Panel further recommended that to permit any experimental validation of the full scale plant, the equipment should be designed in a way that a full scale process can be validated by exposure to representative test organisms.
