Light Intensity Requirements in Abattoir

Recommended light intensities at inspection point, work room & chilling room are respectively:

Correct Answer: 550 Lux, 220 Lux & 110 Lux

The recommended light intensities in an abattoir (measured at 0.9 m from floor; 1.5 m at inspection point) are:

Light Requirements in Abattoir

• Inspection & Packing Point: 550 Lux (50 ft candle) — highest intensity for precise inspection.
• Work Room: 220 Lux (20 ft candle) — moderate for general work.
• Chilling Room: 110 Lux (10 ft candle) — lowest intensity needed.

Memory Tip

Inspection → Work → Chilling = 550 → 220 → 110 (halves each step: 550 ÷ 2.5 ≈ 220; 220 ÷ 2 = 110).

Other Abattoir Requirements

• Floor gradient: 1:50 (2 cm per meter).
• Chilling temperature: not above 7°C for carcasses, 4°C for offals.
• Humidity of carcass chilling room: 90%.
• Temperature of cutting room: not above 10°C.
