Handwashing at a Busy Buka With One Bucket and a Shared Towel

At a busy buka near a motor park in Enugu, one food handler, Ngozi, prepares and serves 120 plates of rice, beans and eba between 11 a.m. and 4 p.m. The only handwash point is a 20-litre bucket of water with a cup, a bar of soap on a dish, and a shared towel. The bucket is filled at 10 a.m. and not changed. Ngozi washes her hands after using the toilet, but she also collects cash, wipes tables, handles raw chicken, and then serves ready-to-eat eba with her bare hands. She says she cannot wash frequently because water is costly and there is no tap. She uses alcohol hand sanitiser after handling cash. At 3 p.m. the towel is damp and smells sour. An environmental health officer visits after a customer complains of stomach upset.

1. Identify the handwashing failures in this buka and state exactly when Ngozi must wash her hands. Is the alcohol sanitiser an acceptable substitute?

Read the worked answer

Failures: the bucket is standing water, not running water; the cup is shared and dips into the water, contaminating it; the soap sits in a dish where water pools; the towel is damp and reused, so hands are recontaminated after washing. The bucket water is unchanged from 10 a.m., so it becomes a bacterial reservoir.

She must wash hands: after using the toilet; after handling raw chicken; after collecting cash or touching money; after wiping tables or touching bins; after touching her face, hair or phone; before handling ready-to-eat eba; and between raw and cooked tasks. Handling cash is not itself a food hazard, but it soils hands and is a reminder that money and food must be separated.

Sanitiser is not a substitute for soap and water, especially on visibly dirty hands; alcohol gels do not remove organic matter and are unreliable against some viruses and spores. Bare-hand contact with ready-to-eat eba is a serious risk; use tongs, a scoop or gloves. The damp shared towel should be replaced with single-use paper towels or air drying.

2. Design a low-cost handwash station and operating routine that would meet the intent of food hygiene rules in this setting.

Low-cost station: a 20-litre container fitted with a tap, raised on a stand, or a tippy-tap with a foot or hand lever; a second container underneath to catch wastewater so the floor is not flooded. Keep bar soap on a small rack that drains, or use liquid soap in a dispenser. Provide single-use paper towels or a clean cloth changed frequently; ideally air-dry. Locate it between the toilet, the raw-food area and the serving point.

Routine: fill with clean water; change water when dirty or at least twice per shift; one person checks soap and towels hourly; wash for at least 20 seconds with soap, rub backs of hands, between fingers, thumbs and nails, rinse under the running tap, and dry. No shared cup and no dipping hands into a bucket. Keep a small log. If running water is truly unavailable, the tippy-tap is the minimum acceptable substitute; a bowl and shared cup are not.

The officer should require correction, not just advise, because bare-hand contact with ready-to-eat food plus a contaminated towel is a credible route for norovirus, S. aureus and faecal bacteria.
