Although there are currently no harmonized maximum
levels for EC, some countries have established their own
criteria (Table 3). Canada firstly introduced maximum limits
for EC in alcoholic beverages in 1985 after high levels of
EC were found in alcoholic beverages. The maximum levels
were 30 μg/L for wine and 400 μg/L for fruit brandies.
The United States has voluntary limits for domestic alcoholic
beverages. Canadian guidelines were adopted by other
countries such as Czech Republic, Brazil, France, Germany,
and Switzerland. South Korea also set the maximum
limit of 30 μg/L only for table wine. There are currently no
guidelines governing the presence of EC in fermented
foods
