Potential sources of error (guessing: no sufficient detail given in the
message):
- you ask scores from eurofood.fa and loadings from eurofood: one of
these names may be wrong.
- you did not ask scores in factanal (they are not there as default, but
you have to specify 'scores').

The cut values are there, but they are not displayed. To see this, you
may try:
unclass(eurofood$loadings)
print(eurofuud$loadings, cutoff=0)
