When you grab a bottle of olive oil from the shelf, you probably imagine liquid gold: pure, heart-healthy, and nourishing. But recent revelations about contaminants hiding in certain olive oils may shake up your shopping habits faster than a Greek salad in a hurricane. Can we still trust all olive oil brands, or are there hidden dangers in your kitchen that need a little extra attention?
The Unseen Side of Olive Oil: Contaminants Lurking in the Bottle
Olive oil is often praised as a champion for health, thanks to its monounsaturated fatty acids that do wonders for your heart. Yet, even this beloved « liquid gold » isn’t always immune to a splash of trouble. Some olive oils have been found to contain unwanted substances—compromising both their purity and health benefits. Among these troublemakers, you’ll meet plasticizers and mineral hydrocarbons, namely MOSH and MOAH. Originally destined as machine lubricants, these substances can sneak into olive oil during transport or storage, making their presence known in places you really don’t want them—your salad dressings and sautés.
Why Some Brands Made the Do-Not-Buy List
- Contaminants are generally present in small amounts, but they can have endocrine-disrupting effects—definitely not what the doctor ordered, especially with regular consumption.
- Small-scale producers are more prone to these contaminants, due to substances migrating from the tanks, pipes, or reservoirs used in harvest and transport.
Recent lab analyses have delivered a sobering message: all tested olive oils contained at least one contaminant, but some brands stood out for the wrong reasons. Among the worst offenders are Terra Delyssa, Carapelli, and Eco+. These brands exceeded acceptable thresholds for MOAH and MOSH and, as if that weren’t enough, had sensory flaws—a stale, moldy, or acidic taste—which drags their « extra virgin » status right through the mud.
- Terra Delyssa
- Carapelli
- Eco+
It’s not all gloom, though. Brands like Puget and Leos rank much better. Puget stands out for low levels of plasticizers and pleasing taste qualities. Even so, a few traces of contaminants still sneak in. And then there’s Costa d’Oro and Vigean: these emerge as the safest bets, free from MOAH and MOSH, and bringing much better taste to your table.
- Puget – low plasticizer levels, good taste, but trace contaminants
- Leos – a better ranking
- Costa d’Oro and Vigean – free from MOAH and MOSH, high sensory quality
Choosing Quality Olive Oil: How Not to Get Fooled
If you’re now staring warily at your kitchen counter, you’re not alone. So, what can you do? Here are some tips (no culinary degree required):
- Prioritize brands with organic production or strict quality certifications. These go the extra mile to avoid contaminants.
- Always check labels for clarity on the oil’s origin and ingredients. This helps guard against fraud and mishaps.
And don’t just stick to what’s trending or the bottle with the fanciest label! Variety is the spice of life (and your pantry): varying your oil sources and not restricting yourself to soy or other popular oils helps you make better, safer choices.
- Organic and certified oils are less likely to be contaminated.
- Read the labels thoroughly—never just take a seller’s word for it.
- Smart shoppers diversify their oils, not just their wardrobes.
And one last hint: trust your palate. A good olive oil should taste fresh, slightly fruity, and hold a hint of bitterness or sharpness, depending on the variety.
The Bottom Line: Vigilance, Moderation, and Smart Choices
Olive oil remains a health ally, but it’s crucial to keep your wits about you when picking products from the shelf. Sticking to moderation, seeking variety, and making informed choices are your best tools. Before you fill your basket, take that extra moment to double-check the origin and ingredients of your olive oil. That simple pause means better flavors and fewer risks for you and your family—so your next meal brings pleasure, not unpleasant surprises.
