Kenya’s Milk Shortage: What Changing Supply Means for Consumers and Businesses

For many Kenyan households, milk is not an occasional purchase. It is part of the everyday shopping basket.

That is why the current milk shortage is more than a supply-chain problem. It is also a story about how consumers respond when a familiar product becomes harder to find, prices change and their usual choices are no longer available.

Across parts of Kenya, retailers have reported lower milk stocks, fewer available brands and delays in replenishment. The Kenya Dairy Board reported that formal milk deliveries to processors fell from 84.4 million litres in June 2026 to 81.3 million litres in July  a 3.7% decline. Preliminary indications for August pointed to a further decline.

What is behind the shortage?

The immediate pressure is largely coming from prolonged dry conditions.

Reduced rainfall has affected pasture and increased pressure on animal feed, making it more difficult for farmers to maintain normal milk production. The Principal Secretary for Livestock Development, Jonathan Mueke, identified fodder pressure caused by the lack of rain as a major factor behind the decline in supply.

The impact is being felt across the dairy value chain  from farmers and cooperatives to processors, retailers and ultimately households.

In some producing areas, the decline has been particularly visible. Kenya News Agency reported that a dairy in Nyeri was collecting about 6,000 litres per day, compared with up to 10,000 litres on a normal working day earlier in the year.

The Kenya Dairy Board has described the situation as temporary and seasonal, noting that pasteurized milk has generally been more affected while long-life milk, including UHT and ESL products, has remained comparatively more available.

But what happens when consumers cannot find their usual milk?

This is where the issue becomes particularly interesting from a consumer behaviour perspective.

When a product that people regularly purchase becomes less available, consumers do not necessarily stop buying it. Instead, they may adapt.

They may:

Switch to another brand.
Choose a different pack size.
Buy long-life milk instead of fresh milk.
Visit a different retailer.
Reduce the quantity they purchase.
Compare prices more closely.
Stock up when they find their preferred product.

Reports from Nairobi and other parts of the country have already shown signs of this behaviour. Some retailers have introduced purchase limits, while certain supermarkets have experienced low stocks and fewer brands or pack sizes.

There have also been significant differences in prices across locations. Recent reporting has found some 500ml packets selling for around KSh90 in parts of Nairobi, while other regions have reported prices reaching KSh100.

For consumers, these changes can turn a routine purchase into a decision.

Which brand is available?

What size can I afford?

Should I buy now or wait?

Is another product a better value?

These are small decisions individually, but collectively they can change how a market behaves.

What does this mean for brands and retailers?

Periods of supply disruption can reveal how strongly consumers are attached to particular brands.

If a shopper cannot find their usual brand, does availability outweigh brand loyalty?

If another brand is consistently on the shelf, does the consumer become more willing to try it?

If prices increase, do consumers move to smaller packs or cheaper alternatives?

These are questions businesses should be asking rather than assuming that consumers will behave exactly as they did before the shortage.

For retailers, availability becomes part of the customer experience. A consumer may remember not only the price of a product but also whether they could actually find it when they needed it.

For dairy brands, the situation can also highlight the importance of understanding substitution behaviour  what consumers choose when their first choice is unavailable.

The bigger market research question

The milk shortage demonstrates why market conditions cannot be understood through supply figures alone.

A decline in supply tells us what is happening in the market.

Consumer research can help businesses understand what people do because of it.

Are households changing their purchasing frequency?

Are consumers switching brands?

Are they becoming more price-sensitive?

Which milk formats are gaining attention?

Are temporary changes becoming permanent habits?

And what happens to brand loyalty when availability becomes the deciding factor?

These questions matter because a temporary supply disruption can potentially create longer-term changes in consumer behaviour.

What should businesses be watching?

The current situation provides several areas worth monitoring:

1. Brand switching
Consumers who cannot find their preferred brand may experiment with alternatives.

2. Pack-size preferences
When prices increase, smaller quantities may become more attractive to price-conscious households.

3. Product substitution
Consumers may move between fresh, UHT and other milk formats depending on availability and price.

4. Retailer choice
Shoppers may change where they buy milk based on availability, convenience and price.

5. Price sensitivity
Changes in the price of an everyday product can influence how consumers evaluate value.

6. Long-term behaviour
The most important question may be what happens after supply normalises. Do consumers return to their previous brands and shopping habits, or do some of the new behaviours remain?

From shortage to insight

Kenya’s milk shortage is ultimately a reminder that markets are shaped not only by what businesses sell, but also by how consumers respond when circumstances change.

Supply disruptions, price movements and changing availability can all create new consumer behaviours.

For businesses, the opportunity is to look beyond the immediate shortage and understand the decisions happening behind every purchase.

Because when the shelf changes, the consumer may change too.

At Research 8020, we believe understanding these shifts starts with asking the right questions  and turning changing market behaviour into insights that businesses can act on.
