To elucidate the effect of egg white lysozyme from Ogol fowl on the preservation of milks, fishcurd and sausage, changes of pH, volatile base nitrogen content and viable cell count were investigated during the storage periods at $20^{\circ}C$, $30^{\circ}C$ and $37^{\circ}C$ after the addition of lysozyme in each foods. Volatile base nitrogen count of raw milk as marker of spoilage was lowest(63 mg%) in 0.05% lysozyme addition lot which was stored at $20^{\circ}C$ for 2 days, and its preservation effect by lysozyme at $30^{\circ}C$ was enhanced with addition of glycine(0.1%). Preservation effect by lysozyme in commercial milk at $37^{\circ}C$ and in fishcurd at $5^{\circ}C$ and $20^{\circ}C$ were also good, and when sausage was stored at $5^{\circ}C$ after treatment of lysozyme instead of sorbic acid, its preservation effect was acceptable.

Total aflatoxin ($B_1+B_2+G_1+G_2$) maximum levels of 15 ${\mu}g/kg$ ($B_1=10\;{\mu}g/kg$) were set for grain, beans, peanut, nuts & their processed food (grinding, cutting etc.), processed cereal product & processed bean product, confectionaries (peanut or nut-containing food), soybean paste, red pepper paste, dried red pepper, processed com products for popcorn and steamed rice. The maximum levels for aflatoxin $M_1$ are 0.5 ${\mu}g/kg$ for raw milk and milks before manufacturing processing. The patulin maximum level is 50 ${\mu}g/kg$ in apple juice and apple juice concentrate (including concentrate to use as raw material and converted by concentration multiple). The ochratoxin A is managed at the maximum levels of 5 ${\mu}g/kg$ in wheat, barley, rye, coffee beans and roasted coffee, 10 ${\mu}g/kg$ in instant coffee and raisin, 2 ${\mu}g/kg$ in Grape juice, concentrated grape juice as reconstituted and wine. The fumonisins ($B_1+B_2$) maximum levels are 4000 ${\mu}g/kg$ in com, 2000 ${\mu}g/kg$ in com processed food (grinding, cutting etc.) and com powder, 1000 ${\mu}g/kg$ in processed com products. Standards for mycotoxins in food have been established and the mycotoxin risk in food is managed reasonably and scientifically, based on risk assessment and exposure analysis.
