Division Interpretation of the test resultsF1
United Kingdom
The limits given refer to each sample unit tested.
The test results demonstrate the microbiological quality of the process tested.
Enterobacteriaceae in dried infant formulae, dried dietary foods for special medical purposes intended for infants below six months of age and dried follow-on formulae:
-
satisfactory, if all the values observed indicate the absence of the bacterium,
-
unsatisfactory, if the presence of the bacterium is detected in any of the sample units.
E. coli , Enterobacteriaceae (other food categories) and coagulase-positive staphylococci:
-
satisfactory, if all the values observed are ≤ m,
-
acceptable, if a maximum of c/n values are between m and M, and the rest of the values observed are ≤ m,
-
unsatisfactory, if one or more of the values observed are > M or more than c/n values are between m and M.
Presumptive Bacillus cereus in dried infant formulae and dried dietary foods for special medical purposes intended for infants below six months of age:
-
satisfactory, if all the values observed are ≤ m,
-
acceptable, if a maximum of c/n values are between m and M, and the rest of the values observed are ≤ m,
-
unsatisfactory, if one or more of the values observed are > M or more than c/n values are between m and M.

n = number of units comprising the sample; c = number of sample units giving values between m and M.

-
For points 2.2.1, 2.2.7, 2.2.9 and 2.2.10 m=M.
- f3
-
The most recent edition of the standard shall be used.
- f4
-
The criterion shall not apply to products intended for further processing in the food industry.
- f5
-
E. coli is used here as an indicator for the level of hygiene.
- f6
-
For cheeses which are not able to support the growth of E. coli, the E. coli count is usually the highest at the beginning of the ripening period, and for cheeses which are able to support the growth of E. coli, it is normally at the end of the ripening period.
- f7
-
Excluding cheeses where the manufacturer can demonstrate, to the satisfaction of the competent authorities, that the product does not pose a risk of staphylococcal enterotoxins.
- f8
-
Only ice creams containing milk ingredients.
- f9
-
Parallel testing for Enterobacteriaceae and Cronobacter spp. shall be conducted, unless a correlation between these micro-organisms has been established at an individual plant level. If Enterobacteriaceae are detected in any of the product samples tested in such a plant, the batch has to be tested for Cronobacter spp. It shall be the responsibility of the manufacturer to demonstrate to the satisfaction of the competent authority whether such a correlation exists between Enterobacteriaceae and Cronobacter spp.
