Bulletin 4

1996-06-21

To: All Holders of the Fish Products Standards and Methods Manual

Subject: Commensal/Parasitic Crabs - New Zealand Mussels

The purpose of this bulletin is to inform manual holders of the tolerance for instances of commensal/parasitic crabs which have occasionally been found in shipments of frozen New Zealand mussels. These small crabs, which are known as pea crabs, reside naturally inside New Zealand mussels. They do not pose a health threat but they could be considered aesthetically offensive to the consumer.

The following tolerance will be applied to all future shipments of New Zealand Mussels:

A unit of New Zealand mussels will be considered defective for the presence of foreign material if any crabs are found during the course of an inspection.

The lot will be considered unacceptable if the total number of sample units found defective for the presence of crabs exceeds the acceptance number for the sample size designated in the sampling plans.

When the Fresh/Frozen Molluscan Shellfish Product Standard is finalised the above tolerance will be integrated in the standard.

Bulletin 3

1994-05-30

To: All Holders of the Fish Products Standards and Methods Manual

Subject: Extraneous Material in Semi-processed Shrimp

The purpose of this bulletin is to inform all manual holders of the tolerance for extraneous material in semi-processed shrimp destined for further processing and labelled as such.

A unit will be considered defective if:

  • 4 or more pieces of seaweed (singly or in combination) which exceed 25 mm in total length are found in a 1 kg sample unit. This tolerance is to be prorated for sample-unit sizes other than 1 kg; or
  • a sample unit contains 5% or more, by weight, of juvenile fish or shellfish.
