Kirkland Signature San Marzano Tomatoes are an imported Italian product consisting of whole peeled tomatoes, San Marzano tomato juice, and a basil leaf. The simple, high-quality ingredients are free of common food allergens, making it suitable for those with sensitivities to dairy, eggs, gluten, and soy. However, an allergen warning is frequently included, indicating that the product may contain traces of milk, soya, eggs, gluten, tree nuts, peanuts, mustard, sesame, sulphites, fish, and celery due to processing in shared facilities. While the risk is low, individuals with severe allergies should be aware of the potential for cross-contamination. The product is vine-ripened and produced in Italy.
