Aflatoxin & Animal Feed.
Why "Apna Chara" Matters.

By Haq Fresh Milk · Updated 11 September 2026

The Short Answer

Aflatoxin is a natural toxin made by certain moulds that can grow on stored crops and animal feed. When a cow eats heavily contaminated feed, a small amount can pass into her milk. The reassuring part is that this is a feed problem before it is ever a milk problem — and the farm that controls its own feed controls the risk. That is exactly why we grow and store our own silage, or apna chara, at our farm in Wapda Town, Lahore.

This guide explains in plain language what aflatoxin is, how it gets into animal feed, and what a Lahore family can reasonably do about it. No scare tactics — just the facts, and the choices that actually make a difference.

The Basics

Aflatoxin, explained simply.

Aflatoxin is not something added to milk. It is a toxin produced by moulds — most commonly Aspergillus species — that can grow on crops and stored feed when conditions are warm and damp.

The crops most often linked to aflatoxin are maize, groundnut and cottonseed, along with other grains and fodder. When a dairy cow eats feed with high levels of aflatoxin, her body breaks down most of it, but a small portion can pass into the milk as a compound called aflatoxin M1.

That sounds technical. The practical point is simple: feed quality is the first line of defence. Clean, fresh, well-stored fodder means lower risk. Mouldy, damp, poorly stored fodder means higher risk.

The Chain of Risk

How mould gets into animal feed.

Mould spores are everywhere in the environment. The question is whether they get the conditions to grow. In practice, three things open the door: a crop harvested in wet weather, fodder that is not dried properly before storage, and feed kept in warm, humid conditions for too long.

This is where market-bought feed becomes a gamble. A dairy that buys mixed feed from an open market often cannot know when it was harvested, how it was dried, how long it sat in a warehouse, or whether it was stored against a damp wall. That missing history is the real risk.

It is also worth saying what aflatoxin is not. You cannot spot it by looking at milk, smelling it or tasting it. Milk from a cow that ate contaminated feed can look and taste completely normal. This is a behind-the-scenes problem, which is exactly why the behind-the-scenes decisions matter so much.

Apna Chara

Why we grow our own feed.

From day one, Haq Fresh has grown its own silage on our farm. Our Dutch cows eat feed we cut, dry and store ourselves, and they eat it fresh. Nothing about that feed is a mystery to us.

Cutting at the right time, drying it properly and keeping storage clean and dry are not glamorous jobs. They are, however, the difference between fodder that is safe and fodder that is not. Because we control every step, we are not exposed to a supplier's storage mistakes.

It also makes the milk more consistent. A steady diet means stable fat and a taste that does not change from week to week. Traceability is not a marketing line here — it is a farming habit.

You can see the fields and the storage for yourself — read more about our farm and how we feed the herd, or come for a visit.

For Your Family

What this means when you buy milk in Lahore.

For a family in Lahore, the useful question is not whether every glass of milk is dangerous — it is not. The useful question is: who is responsible for the feed, and can they tell you where it came from?

When you choose a dairy, ask where the feed is grown and how it is stored. A farm that grows its own fodder will answer easily. A supplier who buys from elsewhere may not be able to answer at all.

At Home

Keeping your family's doodh safe.

There is no household trick that removes aflatoxin from milk. What you can do is reduce exposure at the source and handle milk well once it reaches your kitchen.

Give raw milk a full, rolling boil, then cool and refrigerate it in a clean, covered container. If you keep animals of your own, never feed visibly mouldy or musty chara. When in doubt, throw it out — a few rupees of feed is never worth the risk.
