Which foods contain carrageenan?

It is used to thicken and stabilise: plant-based milks (almond, oat, soy), dairy desserts, ice cream, chocolate milk, squeezable yoghurts, deli and processed meats, jellies and some ready meals. On labels it appears as carrageenan, E407, INS 407 or Irish moss extract.

Is carrageenan the same as seaweed?

It is extracted from red seaweed (including Irish moss), but the purified additive is not the same as eating whole seaweed. The safety debate is specifically about the isolated, processed extract used to thicken foods.

Is carrageenan (E407) safe?

Q: Is carrageenan banned anywhere?

Food-grade carrageenan (E407) is not fully banned in any major market. However, the EU removed carrageenan from infant formula and follow-on formula for infants under 16 weeks as a precaution, and EFSA's 2018 re-evaluation left its acceptable daily intake as only a temporary approval pending better data. Degraded carrageenan (poligeenan) is a different, non-food substance and is not permitted in food anywhere.

Q: What is the difference between carrageenan and poligeenan?

Food-grade carrageenan is a high-molecular-weight seaweed extract used as a thickener and stabiliser. Poligeenan (historically called 'degraded carrageenan') is a low-molecular-weight substance made under harsh acid conditions and is not used in food. Much of the early alarming research used poligeenan, which regulators agree can inflame the gut — but that is not what is added to your food.

Q: Does carrageenan cause gut inflammation?

This is contested. Some laboratory and animal studies, including work published in 2024, report that food-grade carrageenan may affect the gut lining and intestinal permeability. Regulators including the FDA, EFSA and WHO/JECFA currently consider food-grade carrageenan safe at approved dietary levels, while noting individual tolerance varies and calling for more data.

The short answer: regulators call food-grade carrageenan safe at approved levels — but the EU pulled it from infant formula, EFSA's approval is only temporary, and new gut studies keep the debate open. That gap is why we flag it.

US (FDA): Generally Recognized As Safe (GRAS)
WHO (JECFA): safe at dietary levels — but flagged infant-formula use
EU (EFSA): approval kept temporary in 2018 pending better data; removed from infant formula
LabelCop: flags E407 on every label — strictest regulator wins

What is carrageenan?

A thickener and stabiliser extracted from red seaweed (including Irish moss)
Its job in food: stop liquids separating and give a smooth, thick texture
Label names: carrageenan, E407, INS 407, Irish moss extract
Not the same as eating whole seaweed — this is the purified, processed extract

Which foods contain it?

Plant-based milks — almond, oat, soy, coconut
Ice cream, dairy desserts, chocolate milk and squeezable yoghurts
Deli meats, sliced ham and other processed meats
Jellies, jams, some ready meals and canned pet food

In India: increasingly common in plant-based milks, flavoured dairy and packaged desserts — look for INS 407 on the label

What the regulators actually say

Regulator	Status	Reasoning
FDA (United States)	GRAS — permitted	Food-grade carrageenan has been Generally Recognized As Safe since 1972 and is permitted as a stabiliser, thickener and emulsifier. In 2016 the US National Organic Standards Board voted to remove it from the organic list, but the USDA later kept it — a sign the debate is live even where it is legal.
EFSA / European Union	Permitted — temporary approval	EFSA's 2018 re-evaluation found no safety concern at current uses but flagged data gaps, so it kept the group acceptable daily intake of 75 mg/kg body weight as temporary, to be improved within five years. Separately, the EU removed carrageenan from infant and follow-on formula for infants under 16 weeks.
FSSAI (India)	Permitted as an additive	Allowed as a stabiliser/thickener (INS 407) in specified product categories within prescribed limits under FSSAI's additive regulations.
WHO / JECFA	Safe at dietary levels — infant caution	The joint FAO/WHO expert committee considers food-grade carrageenan safe for lifelong use in normal amounts, and drew a clear line between it and degraded carrageenan (poligeenan). It has specifically reviewed — and raised caution about — its use in infant formula.
UK, Canada, Australia	Permitted	Permitted as a food additive; none has adopted a general ban.

Why do regulators disagree?

The confusion starts with two different substances. Food-grade carrageenan is high-molecular-weight; poligeenan (once called "degraded carrageenan") is a low-molecular-weight substance made under harsh acid conditions and is not used in food
The problem: much of the early alarming research used poligeenan — which regulators agree can inflame the gut — not the additive on your label
The open question: some newer studies, including work published in 2024, report that even food-grade carrageenan may affect the gut lining and intestinal permeability
FDA and JECFA: read the food-grade evidence as showing no identified risk at approved levels
EFSA: agreed there's no current concern but wouldn't make the approval permanent — it wants better data, and acted with caution on infants
Both are honest readings of incomplete evidence — we show you the disagreement instead of quietly picking a side

How LabelCop scores it

Carrageenan (E407) is a high-risk flag in LabelCop
Rule: strictest regulator wins — the EU's temporary-only approval and infant-formula removal mean we flag it even where it's fully legal

Frequently asked questions

Is carrageenan banned anywhere?

Food-grade carrageenan isn't fully banned in any major market. But the EU removed it from infant and follow-on formula for infants under 16 weeks, and EFSA's 2018 re-evaluation kept its approval only temporary pending better data. Degraded carrageenan (poligeenan) is a separate, non-food substance and isn't permitted in food anywhere.

What's the difference between carrageenan and poligeenan?

Food-grade carrageenan is the high-molecular-weight seaweed extract used as a thickener. Poligeenan — historically "degraded carrageenan" — is a low-molecular-weight substance made under harsh acid conditions and isn't used in food. Much of the scary early research used poligeenan, which regulators agree can inflame the gut.

Does carrageenan cause gut inflammation?

It's contested. Some lab and animal studies, including 2024 work, report that food-grade carrageenan may affect the gut lining and permeability. The FDA, EFSA and WHO/JECFA still consider it safe at approved dietary levels, while noting individual tolerance varies and asking for more data.

Which label names should I look for?

Carrageenan, E407, INS 407 or Irish moss extract — most common in plant-based milks, dairy desserts, processed meats and jellies.

How do I avoid it?

Read the ingredients list for the names above — or scan the label with LabelCop and it's flagged automatically, with the regulator reasoning shown.
