The effects of zein coating on the total bacterial count, total volatile base nitrogen and histamine in high (5.0 log CFU/g) and low (2.0 log CFU/g) spiked roasted rabbit legs stored at different temperature (−20, 4, 20, and 37 °C) were studied. At 37 °C, the preservation effect of zein film was not obvious. If storage temperature was below 37 °C, zein coating inhibited microbial breeding and histamine production significantly. Freezing (−20 °C) is an effective way to inhibit the growth of microorganisms and histamine accumulation. However, microbes breed rapidly when samples defrosted at 20 °C. Compared to samples without coating, samples coated zein can store for 48 h at room temperature, and the total volatile base nitrogen is still below the threshold (< 30 mg/100 g). These results can provide a reference for the production of high quality meat related products with zein coating.
