Absence in 25 g is a sampling statement
'Salmonella not detected in 25 g' is only as strong as the number of 25 g units tested. Increasing the number of independent units tested is what raises confidence, not repeating the analysis on the same unit.
Recontamination after processing is the common failure
Heat treatment during processing controls the initial load; recontamination then happens in coolers, conveyors, transport and storage. Certificates issued at production do not describe the microbiological state at delivery.
What to verify
- —Number and size of units tested, not just the pass statement
- —Whether the certificate covers the delivered lot or the production batch
- —Transport and storage conditions after processing
- —Supplier's own hygiene monitoring and sanitiser programme
Typical risks
- —Salmonella entry into a hatchery, breeder or dairy chain
- —Cross-contamination of a whole mill after a single delivery
- —Mould growth reducing nutritional value and generating toxins
Common mistakes
- —Accepting a production-date certificate for a cargo stored for months
- —Testing only finished feed and not incoming materials
Frequently asked questions
Which incoming materials deserve routine Salmonella testing?
Animal proteins, oilseed meals and any material with a history of positives in your own intake data. A risk-based plan concentrating on those, with periodic verification elsewhere, is more effective than uniform low-frequency testing.

Moisture is water content expressed as a percentage; it dilutes every other nutrient, drives mould and mycotoxin risk in storage, and is the single most disputed parameter in bulk feed trade.
Sampling is the largest source of error in feed-ingredient testing; a valid result requires many small increments combined into a representative composite, taken to a written plan.
A supplier's quality system — certification scheme, HACCP plan, monitoring programme, complaint handling and recall capability — predicts consistency better than any single certificate of analysis.

Buying feed specified on microbiological quality for a commercial farm
- Best for
- Commercial farms, integrators, distributors and feed buyers sourcing feed specified on microbiological quality and related feed, additives or nutrition supply on a recurring commercial scale — not pet food, hobby farms or backyard quantities.
- Animal species covered
- Broilers and layers, dairy and beef cattle, pigs, tilapia, salmon and shrimp, plus sheep and goats on request.
- Typical feed buyer needs
- A written specification, verified suppliers who can hold that specification, comparable pricing on the same delivery terms, documented quality (CoA, certifications) and a supply schedule that matches production.
- Bulk feed and recurring supply
- Most requests are bulk or big-bag volumes on monthly or quarterly contracts. Volume per delivery, storage capacity on farm and contract length change price more than the headline per-tonne quote.
- Feed additives and premix
- Premix, amino acids, minerals, vitamins, enzymes, organic acids, toxin binders and other additives can be quoted alongside compound feed or ingredients so one supplier comparison covers the whole ration.
- What affects feed cost
- Raw-material origin and specification, inclusion rates, freight and Incoterms, packaging, order volume, payment terms, currency and certification requirements. Landed cost, not ex-works price, decides the winner.
- RFQ checklist
- Species and production stage, tonnes per month, target specification, delivery port or farm location, packaging, required certifications, first delivery date and contract duration.
- Supplier matching process
- You define the requirement, FeedMatch structures the RFQ, sends it to relevant qualified suppliers, and returns comparable offers side by side so you can negotiate on equal terms.
- Buyer is not charged
- Farm buyers are not charged to submit a requirement, receive matched suppliers or compare quotes.
