It is quite safe as long as strict rules of hygiene and safety are observed. Always use fresh, undamaged eggs from a reputable source, store them well before their 'use by' date (so finished mayonnaise can then be stored for up to three days). Bring them up to room temperature by taking them out of the refrigerator about 30 minutes before using.
While eating mayonnaise is safe for most people, raw egg products are not recommended for vulnerable people such as babies, the elderly, pregnant women or anyone who is severely unwell.
