France’s Tuna Scare: Is Your Canned Tuna Safe? Spain Says ‘Yes’ – But Here’s What You Need to Know
A wave of concern is rippling through Europe, and now landing on Spanish shores, as several French cities have removed canned tuna from school menus following reports of mercury levels. But before you ditch your tuna salad, here’s what you need to know: Spanish authorities are reassuring consumers that the canned tuna sold in Spain is safe, adhering to strict European regulations and posing no health risk when consumed in moderation.
The French Controversy: Precautionary Measures Taken
The alarm was triggered by a report from NGOs Bloom and Foodwatch, which analyzed 148 cans of tuna across five European countries. While all samples contained mercury, over 50% exceeded 0.3 mg/kg – a limit applicable to fresh, smaller fish. Tuna, being a larger species, has a higher allowable limit (1 mg/kg for fresh, and up to 2.7 mg/kg in canned due to processing). Despite levels not technically breaching regulations, French cities like Paris, Lyon, and Grenoble opted for a precautionary approach, removing tuna from school lunches. This decision highlights a growing debate about food safety thresholds and protecting vulnerable populations.
Spain’s Response: Calm and Reassurance from AESAN
The Spanish Agency for Food Safety and Nutrition (AESAN) has swiftly responded to the French concerns, urging calm and confirming that official analyses in Spain have detected no breaches of safety standards. “The consumption of canned tuna does not represent a risk if it is performed in moderation,” AESAN insists. Recent analysis by the OCU (Spanish Consumers Organization) further supports this, revealing average mercury levels in canned tuna at just 0.14 mg/kg – well below the legal limit.
Understanding Mercury in Fish: A Deeper Dive
Mercury is a naturally occurring element, and all fish contain some level of it. Larger, longer-lived predatory fish, like tuna, tend to accumulate more mercury in their tissues. However, it’s crucial to understand the different types of tuna. The canned tuna commonly found in Spain primarily comes from skipjack (smaller, reddish meat) or yellowfin/yellow end (medium-sized) tuna – species with comparatively lower mercury levels. Red or bluefin tuna, a larger species, is not used for canning due to its higher mercury content and is generally not recommended for children, pregnant women, or breastfeeding mothers.
EU Regulations: Setting the Standards
European Regulation (EU) 2023/915 sets clear maximum limits for contaminants in food, including mercury. These limits vary based on fish size and whether the product is fresh or processed. Here’s a breakdown:
- Smaller Fish: Maximum 0.3 mg/kg
- Tuna & Other Larger Fresh Fish: Maximum 1 mg/kg
- Canned Tuna (Processed): Maximum 1 mg/kg (equivalent to 2.7 mg/kg considering moisture loss during processing)
Protecting Vulnerable Groups: AESAN’s Recommendations
While canned tuna is considered safe for most, AESAN provides specific guidance for certain groups:
- Children under 10, Pregnant & Breastfeeding Women: Avoid high-mercury species like swordfish, shark, and red tuna.
- Children aged 10-14: Limit consumption of high-mercury species to less than 120g per month.
Canned tuna, sourced from lower-mercury species, isn’t restricted for any age group when consumed in moderation as part of a varied diet.
The situation unfolding in France serves as a vital reminder of the importance of ongoing food safety monitoring and informed consumer choices. In Spain, the message is clear: enjoy your tuna, but do so responsibly, as part of a balanced and diverse diet. Stay informed about food safety updates and recommendations from trusted sources like AESAN and OCU to ensure you’re making the best choices for your health and the health of your family.
