Why Do Farms and Stores Chill Milk and Meat Quickly?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do farms and stores chill milk and meat quickly?

The Big Idea

Farms and stores chill milk and meat quickly because cold slows down bacteria! Bacteria grow fast in warm places and slowly in cold ones. Fast cooling keeps these foods safe from the farm all the way to your fridge.

Bacteria Love Warmth

Step one: bacteria love warmth. Bacteria are tiny living things that can double in number in as little as twenty minutes when it is warm. Milk and meat are rich in water and protein, which makes them perfect bacteria food.

Cold Slows Them

Step two: cold slows them. At fridge temperature, around 4 degrees Celsius, bacteria grow far more slowly. Dairy farms chill milk right after milking for this reason.

The Cold Chain

Step three: the cold chain. Milk and meat stay cold on the farm, in trucks, in stores, and at home. A break in that chain lets bacteria speed up again.

A Closer Look

Let's take a closer look at the cold chain! On the farm, milk goes into a chilled tank. A refrigerated truck carries it onward. The store keeps it in a cold case. And your fridge is the final link.

Quick Facts

Quick facts! The cold chain is a safety chain. Chilling does not kill all bacteria, it only slows them. Frozen food is cold enough to pause bacteria almost completely. Ask a grown-up to handle thermometers and the fridge.

Think Like a Scientist

Now, think like a scientist! With a grown-up, put the same amount of warm, not hot, water in two cups. Put one in the fridge and one on the counter. Check each with a thermometer after 30 minutes. Compare the two temperatures after 30 minutes.
