To add the EU perspective on fish parasites, European hygiene legislation
requires all "fishery products to be eaten raw or almost raw" to be frozen
to -20°C or colder for not less than 24 hours at some point along the
production chain. A document from the manufacturer stating the process
undergone has to accompany the fish as it changes hands. This is detailed in
Regulation 853/2004 in Annex III, Section VIII.
There are moves afoot here in the UK to launch an awareness campaign on this
requirement aimed specifically at sushi restaurants.

To add to Amilcar's comments, the small tunas are referred to in Chapter 3,
"Potential Species - Related & Process - Related Hazards," Table 3-1,
Potential Vertebrate Species Related Hazards, of the FDA's Fish and
Fisheries Products Hazards and Controls Guidance, 3rd edition, 2001 and is
available on the Internet (http://www.cfsan.fda.gov/~comm/haccp4c1.html
<http://www.cfsan.fda.gov/~comm/haccp4c1.html> ) :
Allothunnus fallai
Auxis spp.
Euthynnus spp.
Katsuwonus pelamis
Thunnus tonggol
The table of contents is at: http://www.cfsan.fda.gov/~comm/haccp4.html
<http://www.cfsan.fda.gov/~comm/haccp4.html>
Note: the US Food and Drug Administration is updating the "Hazards Guide".
When information on the revisions are available, it will be announced on
this listserv (among other sources) - perhaps by late March or earlier.

Well, guys, if you look at the "Fish and Fisheries Products Hazards &
Control Guidance" (third edition), there are some Tuna (specially small
ones) that do have parasite's hazards. That's on page 36.
