The "5.4 regulations" deal with five issues, each divided into four topics, that need attention:
1. employees (buyers, cooks, waiters) should see to it that no rotten products are used;
2. food should be separated: cooked from raw; half-products from unused products, etc.;
3. implements should be washed and sterilized;
4. the establisment should be run by fixed standards (employees, prices, furniture, operating hours);
5. personal hygiene of employees (hands, hair, clothing, etc.).
