Dear All,
A few comments.
Numerical microbiological measurements typically show large variations in agreement, (both intra and inter) due to a variety of reaons, sampling/procedure/natural produce/experience etc. And national specifications are also (IMEX) amazingly variable for many items, probably even within the EU also. Some of them simply do not make bacteriological sense.
Note that the EU / E.coli data are intended as a process hygiene indicator. (And I guess no bactericidal step in the fruit chain). A consistent level of >100/g would (rightly IMO) immediately indicate something wrong also (after a check on the procedure). Anybody got some typical process data for peeled fruit available (which still considered “enjoyable” to eat )?
How about meat preparations with E.coli max 5000/g (even though it will be cooked later) ?. Reasonable ??
Interestingly, some of the E.coli limits in some of the other cooked foods might be considered too strict (eg crustacea) (see next paragraph).
The general UK guidelines (E.coli et al) at point of sale are linked below, only 10x less than EU for fruit. How do you people feel about that ? Change in tourism plans for some maybe.
http://www.hpa.org.u...C/1194947422163A specification of “zero” is usually regarded as meaningless unless interpreted / defined in the sub-text.
One factor is as spelled out in UK document, any limits must be legally (and thereby hopefully scientifically) defendable (note the right hand column in table 1). Many proposed national and international microbiological specifications have come to grief over that requirement. Another one is the Codex suggested requirement of “realism”, eg chicken meat is allowed to be sold in many (most?) supermarkets with Salmonella. An acceptance of farming reality (incompetence?) perhaps.
Regardless of the above caveats, I would also like to see the risk assessment which preceded the EU selection of limits / guidelines. I suspect that the US requirements for E.coli in fruit/vegetables will be tougher in view of their bad experiences with these items, ie an increased "severity" contribution.
