Food Safety for Tea, Coffee and Dry Goods Producers

Lower risk, not no risk

If you produce tea, coffee, spices, dried herbs, or similar dry goods, there's good news: your products are inherently lower-risk than moist, ready-to-eat foods. The very low water activity of dry products means harmful bacteria struggle to grow, which removes a whole category of hazard that dominates other producers' plans.

But lower risk is not no risk, and dry goods carry their own specific hazards that a good food safety system has to manage. This guide looks at food safety for dry goods producers and how to build a plan that's proportionate, neither overcomplicated nor complacent.

Why low moisture helps so much

Most foodborne illness comes from bacteria multiplying in food, and bacteria need available water to grow. Dry products, with their very low water activity, simply don't provide it. A properly dried tea, a bag of coffee beans, or a jar of dried spice is microbiologically stable in a way that a fresh chilled product never is.

This is why your hazard analysis will likely show fewer biological hazards from bacterial growth than a producer of moist foods, and why you may have fewer or different critical control points. It genuinely is a simpler picture in that respect, and your plan should reflect that rather than importing hazards that don't apply to you.

The hazards that do apply

Lower microbiological risk doesn't mean an empty hazard analysis. Dry goods producers should pay attention to:

1. Physical hazards. Often the most relevant category. Stones, stalks, foreign material in raw agricultural products, packaging fragments, and equipment parts. Sieving, sifting, or other foreign-body controls may be important, and could even be critical control points.
2. Chemical hazards. Mycotoxins are a genuine concern: these are toxins produced by moulds that can grow on grains, nuts, coffee, and spices if they've been stored or dried improperly at some point in the supply chain. Pesticide residues and contaminants in raw materials also fall here.
3. Allergenic hazards. Several of the 14 allergens are relevant to dry goods, particularly through cross-contact. Nuts, sesame, mustard, celery, and cereals can all feature, and shared equipment for different products is a real cross-contact route. Spice blends in particular can carry multiple allergens.
4. Biological hazards. Reduced, but not entirely absent. Some dried products have been implicated in contamination (certain spices, for example), and the assumption that "dry equals sterile" is wrong. Raw material safety still matters.

Supplier control is central

For many dry goods producers, the most important control isn't something you do in your own facility, it's the quality and safety of what you buy in. Tea, coffee, and spices often come through long, international supply chains where mycotoxin, contaminant, and adulteration risks arise well before the product reaches you.

This makes supplier approval and raw material risk assessment especially important. You need confidence in your suppliers, specifications for your materials, and traceability back through the chain. Our guide to supplier approval and management covers how to build this, and it's worth treating as a priority control rather than an afterthought.

Cross-contact and allergens in blends

If you blend or pack multiple products, particularly spices and seasonings, allergen cross-contact deserves real attention. Shared equipment, scoops, and surfaces can transfer allergens between products, and a blend can contain several allergens that all need declaring. The controls are separation, cleaning between products, and rigorous labelling. Our guides to cross-contamination and the 14 allergens cover the detail.

Keep the plan proportionate

The key to dry goods HACCP is proportionality. The risk of overcomplicating is real: importing a plan built for a high-risk producer leaves you defending biological hazards and critical control points that don't genuinely apply to a stable, low-moisture product, which an auditor will see through. Equally, complacency, assuming dry means safe and skipping the physical, chemical, and allergen hazards that do apply, is its own failure.

Building your plan around your actual products and process is what gets the balance right. Sage works through what you produce and how, and applies consistent food safety logic, so your plan reflects the genuinely lower biological risk of dry goods while still capturing the physical, mycotoxin, and allergen hazards that matter for your specific products. You end up with a plan that's proportionate to your real risk, neither bloated nor naive.

The takeaway for dry goods producers

Tea, coffee, spices, and dried goods are inherently lower-risk thanks to low water activity, and your food safety plan should reflect that simpler picture rather than borrowing hazards from wetter, riskier foods. But give proper attention to the hazards that genuinely apply: physical contamination, mycotoxins and chemical contaminants, allergen cross-contact in blends, and the safety of what you buy in through often long supply chains. Get supplier control right, keep the plan proportionate, and you'll have a system that fits your products honestly.
