What Lamb Weston Super Crispy Shoestring Fries is made of, ingredients and materials
Lamb Weston Super Crispy Shoestring Fries are potato product in a paper/cardboard bag with a grease-resistant interior coating. The coating prevents oil migration during storage and shipment but its chemical composition is not publicly disclosed by the brand. Grease-resistant food packaging commonly uses PFAS (fluorinated compounds), though alternatives exist; Lamb Weston has not specified which technology they employ in this product.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Acrylamide (cooking byproduct)
High-temperature frying produces acrylamide, a probable carcinogen. This is inherent to all french fries, not brand-specific. Cooking at lower temperatures and avoiding charring reduces exposure.
Sodium content
Frozen fries are typically high in sodium for preservation and flavor; Lamb Weston product contains significant added salt. Not a safety hazard per USDA standards but relevant for individuals managing hypertension or dietary sodium limits.
Coating degradation and food contact leaching
If the grease-resistant coating is polymer-based, prolonged storage or exposure to moisture/temperature fluctuation may degrade it. Without coating-material transparency, potential leaching cannot be ruled out but is unlikely at normal storage temperatures.
Pesticide residue
Potatoes are conventional commodity crops often treated with fungicides and herbicides. Residues in frozen fries depend on agricultural sourcing, which Lamb Weston does not disclose by supplier or region. Testing by independent laboratories would be required to confirm residue levels.
Source, EPA ↗What’s reassuring
Microbial contamination from processing
No recalls for microbial pathogens or contamination are on record for this product. Frozen fries are blanched and par-fried during manufacturing, which reduces microbial load; consumer reheating is the primary contamination vector if utensils or cooking surfaces are not clean.
How is this PFAS grade calculated?
The brand's record and disclosure
Lamb Weston is a major frozen potato processor owned by ConAgra. The company has not publicly committed to PFAS-free packaging or released ingredient transparency statements for bag linings on this product line. No major recalls or safety controversies specific to this product are on record with the USDA or FDA. The lack of proactive disclosure on food contact packaging chemistry is consistent with industry-wide hesitancy rather than flagged misconduct.
How it compares in its category
Frozen french fries across major brands (McCain, Ore-Ida, store brands) face identical packaging uncertainty; few manufacturers disclose grease-resistant coating chemistry publicly. This product is standard for the category in safety profile and labeling opacity. Competitor transparency on PFAS packaging is similarly poor, making differentiation difficult without direct brand outreach.
If you buy it
Follow package storage instructions; keep unopened bags in cool, dry conditions away from heat sources. Do not store fries in the original bag long-term after opening; transfer to sealed containers to limit air exposure and potential coating contact with moisture. Use product within the printed shelf-life window. If concerned about PFAS exposure, contact Lamb Weston customer service requesting specific packaging material composition.
