Subway Cruelty

Filth, cruelty and racial discrimination


Do you eat at Subway? If so, you may want to think again. A shocking new investigation in Asia reveals food safety risks and extreme animal cruelty at the supplier to Subway’s egg products producer.

On this supplier’s farms, feces and dirt are caked on the bars of cages where eggs are laid, and feces piles up just inches away from eggs and from the birds themselves. Eggs are smeared with feces and collect on dirt-covered equipment. Mother hens are crammed for nearly their entire lives in cages so small and cruel they are illegal in numerous countries.

Subway has set a timeline for using only cage-free eggs in North America, South America and Europe, but has made no such commitment for Asia—even though cage-free eggs are widely available, and dozens of leading food companies including Starbucks, Kellogg’s, Kraft, Nestle and Compass Group have already set timelines for going cage-free there.

It’s time for Subway to stop discriminating against Asian customers, and set a timeline to end its use of eggs from filthy and cruel caged egg farms.

Please sign the petition!

Subway: I won’t eat at your restaurants again until you treat Asian customers equally and set a timeline to stop serving eggs from hens packed in dirty, cruel cages. It’s time for Subway to go 100% cage-free!

Egg safety - Food safety risks

Food Safety Risks Of Caged Eggs

Over a dozen scientific studies have found that caged egg farms have dramatically higher rates of salmonella contamination. The European Food Safety Authority conducted the largest study ever on the issue, analyzing data from five thousand farms. It found that caged egg farms are 25 times more likely to be contaminated with key salmonella strains. (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17)

There are numerous reasons why packing hens in cages causes food safety risks. Research by the USDA shows the stress of cage confinement makes hens more vulnerable to disease. Cages are also hard to clean and disinfect, leading to “a larger volume of contaminated fecal material and dust.” (18, 19, 20, 21, 22, 23)

Caged Eggs Are Cruel

Just like dogs and cats, chickens are smart, intelligent individuals that feel pleasure and pain. Packing an animal for nearly her entire life in a cage so small she can barely turn around is simply wrong. (24)

Battery cages are so cruel they have been banned in Michigan, Massachusetts, California, and numerous other states, as well as in dozens of countries. Every mainstream animal protection organization in the U.S. and around the world condemns battery cages as cruel and inhumane. (25, 26, 27)

Here is what just a few such organizations have said:


“Intensive farm animal confinement is barbaric and out of line with contemporary values.”

American Society for the Prevention of Cruelty to Animals


“Hens in cages are more prone to stress and injury, and an increased risk of salmonella.”

World Animal Protection

Humane Society International

“It’s inhumane for hens—intelligent, active animals—to be confined to cages so small they can barely move an inch for almost their entire life.”

Humane Society International

High quality video footage and photos from the investigation are available for download here. All video clips and photos are in the public domain and can be downloaded and used freely by anyone, including the media.

Subway buys and serves egg patties from processed foods company SureWin Food (祥旺食品). SureWin uses eggs from egg producer Tainan Egg Products (台南蛋品股份有限公司). All video and photos on this site are from farms of Tainan Egg Products. The specific farms shown are named Wel Leung Farm (偉良畜牧場) and Zhenliang Farm (振良畜牧場).

Video proof the footage was taken at these Tainan Egg Products farms, documentation that Tainan Egg Products supplies eggs to SureWin, and documentation that Subway purchases its egg products from Tainan, is available here.
