A search for single-top production, ep -> etX, has been performed with the ZEUS detector at HERA using data corresponding to an integrated luminosity of 0.37 fb-1. No evidence for top production was found, consistent with the expectation from the Standard Model. Limits were computed for single-top production via flavour changing neutral current transitions. The result was combined with a previous ZEUS result yielding a total luminosity of 0.50 fb-1. A 95% credibility level upper limit of 0.13 pb was obtained for the cross section at the centre-of-mass energy of sqrt{s}=315 GeV.
