Practical Pathogen Environmental Monitoring (EMP) and Surface Swabbing

The laboratory rings at two on a Thursday, and what happens in the next hour decides everything

Listeria spp. detected, assembly belt B3, sampled Monday. Between that call and the end of the shift somebody has to decide whether four batches of chilled ready meals move or stay, which fifteen to thirty sites get sponged tomorrow before anyone is allowed to scrub, and what to tell the production manager standing at the door. Plants that have a written programme do this calmly. Plants that have a sampling list and a laboratory contract improvise, clean first, get a clean star burst that proves only that scrubbing works for a day, and meet the same strain again in March.

What does the EMP course cover? 6 modules, 26 lessons, 15 narrated videos

Every module ends with a knowledge check and a game: Whose rule is it?, Name that bug, Name the zone, Which sponge?, The laboratory rings and Gate keeper. Each one puts you on a site at the moment somebody has to decide, 45 seconds a decision. Between the lessons sit scenario checks and a case study assessment for each module, and the workshop ends in four timed practical stages on the case plant. The full curriculum with every lesson, video, quiz and practical stage is listed further down this page under Course Content.

The world learnt the cost in South Africa in 2017 and 2018: 1 060 confirmed listeriosis cases and 216 deaths, the largest listeriosis outbreak ever recorded, with the outbreak strain found across the environment of one factory. This course is the programme that finds a resident before the product does. It takes you from the growth table and the organisms, through zoning and the plant walk, the sponge and the broth, the laboratory and the data, to the first hour after a positive and the root cause an auditor accepts. Then it makes you build one: a complete environmental monitoring risk assessment for a case plant or your own, scored on the 5 x 5 matrix in the ASC RA19 structure and yours to keep, with four timed practical stages on the case plant that test every call it asks you to make, marked the moment you submit.

An environmental monitoring programme (EMP, or environmental monitoring program in US usage) is the documented, risk based sampling of a food plant’s surfaces and environment, zoned from Zone 1 (food contact) to Zone 4 (outside the processing area), to find pathogens such as Listeria monocytogenes and Salmonella in their harbourage sites before they reach product. FSSC 22000 Version 7 clause 2.5.7, BRCGS Food Safety Issue 9 clause 4.11.8 and Codex CXG 61 Annex I require one; South African Regulation R638 does not, and sets only a cleaning verification limit of 100 viable microorganisms (cfu) per square centimetre on a cleaned food contact surface. This course teaches you to build, run and defend that programme.

Built by practitioners who have stood at that door

The material was written and reviewed by food safety consultants, microbiologists, hygiene managers and auditors who run environmental monitoring programmes on South African and international sites, against the July 2026 revision of the Codex Listeria guideline (CXG 61, Annex I), FSSC 22000 Version 7 clause 2.5.7, BRCGS Food Safety Issue 9 clause 4.11.8, the ISO surface sampling and detection methods, the FDA and FSIS guidance, the 3M Environmental Monitoring Handbook, the FSSC guidance document on environmental monitoring, and Regulation R638. Every figure in the course names its source, so you can quote it when a laboratory, a supplier or an auditor pushes back.

Practical Pathogen Environmental Monitoring (EMP) and Surface Swabbing. Document code FS32-0401. Advanced level, 9 hours, self paced, online, on any phone. R1 750, paid in South African rand through PayFast, with lifetime access. That is a small fraction of one held batch of chilled product, and less than most plants spend on a month of sponges, broth and laboratory fees; the note you write in the workshop will put your own rand figure next to it. Indicative equivalents in nine currencies are shown on this page.

What this course is not

It is not a Listeria awareness course, and it is not a slide deck about swabbing with a quiz at the end. It is not a one organism course either: the wet chilled pathogens, the dry plant survivors, the toxin formers, the spoilage yeasts, the acid loving spore formers of juice and cider, and the moulds that leave aflatoxin behind all get their place, with where each lives in a plant, the foods it takes, and the control that beats it. It expects numbers from you: a probability and a severity on every line, a residual rating that sets a frequency, a swab budget that either fits or is argued for, a broth that matches the sanitiser in each area, a release rule with both halves present, and a root cause that stops at a purchasing or design decision and never at cleaning failure. If you want a wall certificate without building a programme, this is the wrong course.

Can I buy this course from outside South Africa?

Yes. The price is in South African rand and payment settles in rand through PayFast; the page shows indicative equivalents in nine currencies. The method is international: Codex CXG 61 Annex I, FSSC 22000 Version 7, BRCGS Issue 9, ISO 18593, ISO 11290-1, ISO 6579-1, ISO 21528-2 and ISO 4833-1, the FDA 2017 draft guidance and the FSIS 2014 Listeria guideline, and the growth data of the FDA, the New Zealand and Irish food safety authorities. The South African law content, R638 regulation 6(4)(b)(i) on the cleaned surface and R607 of 2018, which made HACCP compulsory for RTE heat treated meat and poultry processors, sits in clearly marked sections and is kept because it is the cleanest worked example of a legal limit on a cleaned surface, 100 viable microorganisms per square centimetre, that most schemes leave open.

Who is this environmental monitoring course for?

• QA and technical managers who own the environmental monitoring programme and answer for it at FSSC 22000, BRCGS, IFS or SQF audits
• Hygiene and sanitation managers who are blamed for every positive and want the evidence that shows where it really came from
• Laboratory coordinators, microbiologists and technologists who sample, submit and read the results
• Production and maintenance managers who have to hold product, open equipment and fund the fix
• Food safety team members, HACCP team members and persons in charge under R638
• Consultants, auditors and laboratory account managers who need the clause, the number and the method in the same sentence
• Packhouses, central kitchens, dairies, bakeries, beverage plants, meat and ready meal plants: the case sites cover a chilled ready meals plant, a citrus packhouse and a restaurant production kitchen

Who it is not for

This is an advanced course. It assumes you know what a food contact surface, a kill step and a cleaning schedule are, and that you have seen a laboratory report. It does not teach basic hygiene or HACCP. If you need those, start with the ASC food hygiene and HACCP courses and come back; the nine hours here will then be worth a great deal more.

This course is the pathogen control course of the ASC Food Microbiology series. It sits after Introduction to Food Microbiology, Intermediate Food Microbiology and Advanced Food Microbiology, and it is the one that puts the microbiology onto a floor plan and into a programme.

What you will be able to do after it

• State the outbreak figures an auditor expects you to know and say exactly what South African law requires of a cleaned surface, and what it does not require, so you can answer the question about a legal EMP without guessing.
• Quote the elements of a programme that FSSC 22000 Version 7 clause 2.5.7 (a) to (d), BRCGS Issue 9 clause 4.11.8 and Codex CXG 61 Annex I require, and the five triggers that force a review.
• Read a growth table and say which organisms a product, a chiller, a dry store or a cooling tunnel can support, and for how long.
• Name the pathogens of wet chilled plants and of dry and ambient plants, where each lives in a factory, the foods it is linked to, and whether you prevent it, eliminate it or control it.
• Name the spoilage organisms and mycotoxin producers behind the common defects in juice, cider, bakery, dairy, meat and canned foods, and where each comes from in the plant.
• Tell a visitor from a resident strain from a year of results, and explain with the arithmetic of regrowth why a resident is not a cleaning failure.
• Zone every surface on a line with the two question rule, walk a plant three times following the water, and mark the vectors and the growth niches on the plan.
• Choose the pathogen, the index organism and the indicators for a wet plant and for a dry plant, and explain why the routine test is Listeria spp. and not Listeria monocytogenes.
• Score every site inherent and residual on the 5 x 5 matrix, read the residual band into a frequency, and build a rotation that fits a swab budget or shows management the gap.
• Specify the sponge, the swab and the neutralising broth for every area against the sanitiser in use, and explain why a Letheen sponge or a neutralising buffer on a peracetic acid line hides positives while Dey Engley (D/E) and HiCap broths do not.
• Take a sponge sample that will stand up, in ten steps, and train a supervisor to do the same.
• Get a sample to an accredited laboratory chilled and signed for at every handover, read the schedule of accreditation, and act on a presumptive.
• Run the cleaning verification programme that satisfies R638 without confusing it with the pathogen programme.
• Turn a year of results into a baseline, alert, action and escalation levels, a heat map, a hit rate and a repeat site list.
• Run the first hour after a positive from a printed sequence: log it, map it, decide the product, tell the people who act, star burst in six directions before the intensified clean, hold and test, release on both halves of the rule.
• Plan a seek and destroy teardown, prove a resident with typed isolates, and write a root cause and CAPA that reaches a design or system cause.
• Build, export and defend a complete environmental monitoring risk assessment in the ASC RA19 structure for a case plant or your own.

You leave with a generated environmental monitoring risk assessment

This is the part no other course gives you. The workshop does not end in a quiz; it ends in a document. The EMP Programme Builder takes what you enter across the three sittings and generates your environmental monitoring risk assessment in the structure of the ASC RA19 Environmental Monitoring Risk Assessment, the same workbook ASC sells to plants preparing for FSSC 22000 Version 7: How to Use, Programme Design mapped to clause 2.5.7 (a) to (d), the Risk Register with columns A to T scored inherent and residual, the Matrices with the scoring legend and heat maps, the Action Tracker for every Medium or higher line, and the Review Log with the five triggers, plus the Schedule, the Targets and methods, the Action levels and the Positive drill and CAPA sheets built from the register. Build it on your own plant and it is your programme, ready for the food safety team to approve. Build it on the case plant and it is the worked example you take to your own.

The free EMP package you take away

Most training leaves you with notes. This one is built so that the week after you finish, there is a programme on your desk and a record in your file.

Can I do the course without a factory? The three case sites

Every case pack, activity and practical stage runs on a provided case site, so a delegate between jobs, studying, consulting or working off site can complete the whole course. Three sites carry the work:

• Mzansi Fresh Meals, chilled ready meals in Gauteng. 400 people on two shifts, a 12 day shelf life, a high care assembly hall at 4 degrees Celsius, twenty four sites from the walk with their swab history, a belt with a positive eight months ago, a drain with three, and a swab budget of 25 a week. This is the main site.
• Sundays River Citrus Packhouse in the Eastern Cape. Wet dump tank, brush beds, chlorine and packhouse drains, with a new juice room, so Alicyclobacillus, the preservative resistant yeasts and the moulds get their turn.
• Umhlanga Kitchens in KwaZulu-Natal. A central production kitchen supplying sixteen restaurants with chilled cooked components on a 5 day shelf life: a slicer that is not dismantled nightly, vacuum packed smoked fish, and a cracked floor around a drain.

The cases are training scenarios built from patterns that real investigations and audits keep finding. No company is named in any of them.

Which standards does the course teach against?

Every rule in the course is tied to the document it comes from. When a laboratory, a supplier or an auditor asks where a number came from, you show them the clause.

The course is built on Codex, the GFSI benchmarked schemes, the ISO methods and South African law. It is not approved or endorsed by Codex, FSSC, BRCGS or any scheme owner, and we do not claim that it is.

How is the course assessed?

• Six knowledge checks, one per module: 15 questions drawn at random, so no two papers are the same. Thirty seconds a question, 70 percent to pass, three attempts.
• Six games, one per module: 12 scenarios, 45 seconds a decision, 70 percent, three attempts.
• A final assessment of 30 questions drawn at random, so every attempt is different. Thirty seconds a question, 70 percent to pass, three attempts, video proctored on any phone or laptop camera, with copy and paste blocked.
• Five scenario checks, placed between the lessons of Modules 1 to 5: 4 questions drawn from a bank, 5 minutes, 70 percent to pass.
• Five module case study assessments, one each for Modules 1 to 5, set on the course case sites: 10 questions drawn from a bank, 10 minutes, 70 percent to pass.
• Four practical stages that close the workshop in Module 6, set on Mzansi Fresh Meals with the plant data on screen: the risk register lines, the scoring and the schedule, the targets and action levels, and the positive drill, the action tracker and the note to management. Each is 12 questions drawn from a bank, 15 minutes, 70 percent to pass, and together they test the seven criteria your risk assessment is built to.

Every question is written against the lessons and verified twice. Every activity is compulsory and timed, and everything is marked automatically the moment you submit, with nothing to upload and no marker to wait for. Every answer returns feedback that names the lesson to revisit, so the second attempt is a better one and not a re roll.

About the trainer

Trainer: ASC Team. This course was compiled by the ASC Food Safety Consultants team with a panel of food microbiologists, hygiene managers, laboratory managers and GFSI scheme auditors, and built on Codex CXG 61 Annex I, FSSC 22000 Version 7, BRCGS Food Safety Issue 9, ISO 18593 and Regulation R638. Content reviewed in September 2026 against the July 2026 Codex revision.

Frequently asked questions about the EMP course

Is an environmental monitoring programme a legal requirement in South Africa?

No. Regulation R638 sets one limit, 100 viable microorganisms per square centimetre on a cleaned food contact surface, and says nothing about pathogens in the environment. The duty to look for Listeria comes from FSSC 22000 Version 7 clause 2.5.7, BRCGS Issue 9 clause 4.11.8, your own hazard analysis and the Codex guideline. The course teaches you to answer that question in an audit without guessing.

Is it only about Listeria?

No. Module 2 covers the wet chilled pathogens, the dry plant survivors Salmonella and Cronobacter, the toxin formers Bacillus cereus, Staphylococcus aureus and Clostridium perfringens, the spoilage yeasts and Alicyclobacillus of juices and ciders, and the moulds and aflatoxins of grain, nuts and spices, each with its environment, its foods and its control. Listeria spp. is the index organism of a wet chilled plant, which is why it carries the routine programme.

Do I need to be working at a factory?

No. Every case pack, the activities, the workshop and the practical stages run on the three provided case sites with full data, so you can complete the course without access to a plant. If you are on a site, you do the same tasks on your own plant and walk out with a risk assessment for it.

Is Listeria testing on surfaces a legal requirement in South Africa?

No. R638 regulation 6 sets a limit of 100 viable microorganisms per square centimetre on a cleaned food contact surface and does not mention Listeria. Listeria environmental monitoring is required by FSSC 22000 Version 7 clause 2.5.7, BRCGS Issue 9 clause 4.11.8 and Codex CXG 61 Annex I.

What is the difference between an environmental monitoring swab and a cleaning verification swab?

A cleaning verification swab counts total viable microorganisms on a cleaned surface against the R638 limit. An environmental monitoring swab looks for a named organism, usually Listeria spp., about three hours into production, to find harbourage sites. The course keeps them in separate programmes with separate records.

What is the generated risk assessment?

The EMP Programme Builder takes your register, scores, schedule, targets, action levels, positive drill and CAPA and exports them as a spreadsheet in the structure of the ASC RA19 Environmental Monitoring Risk Assessment: How to Use, Programme Design, Risk Register, Matrices, Action Tracker and Review Log, plus the programme sheets. It is yours to keep and rebuild.

Is everything really marked automatically?

Yes. There is no assignment to upload. The knowledge checks, games, scenario checks, case study assessments, the four practical stages and the final assessment are all marked the moment you submit, and the feedback names the lesson to revisit. The EMP Programme Builder is your working tool: its review gate checks counts, scores, schedule, broths, levels, the star burst, the root cause against a list of rejected symptoms, owners and dates, and the note before it exports the workbook, which you keep.

Is this course accredited?

ASC Food Safety Consultants is a training provider whose courses carry HPCSA CPD accreditation. The course is built on Codex CXG 61, FSSC 22000, BRCGS, the ISO methods and South African law, but it is not approved or endorsed by any scheme owner, and we do not claim that it is.

I am outside South Africa. Will it apply to my plant?

Yes. The Codex guideline, the scheme clauses, the ISO methods and the FDA and FSIS patterns are international, and the builder and the workbook are written against them. The South African regulation is one marked section. You pay in rand; the page shows indicative equivalents in nine currencies.

How long does it take and how long do I have?

About nine hours of lessons, videos, activities and assessments, self paced. Most delegates finish in two to three weeks, doing the workshop in three sittings of about an hour each. Your access does not expire, so you can go back into the lessons, the builder and the toolkit whenever the plant changes. If your company needs a set access period stated on a purchase order, ask ASC before you enrol and it will be confirmed in writing.

What happens after I pay?

PayFast returns you to the site, the course appears under Learner portal, my courses, within a minute, and Module 1 opens at once. The certificate downloads from the same place when every assessment is passed.

Will it help with my FSSC, BRCGS, IFS or SQF audit?

It teaches the environmental monitoring requirements directly, FSSC 22000 Version 7 clause 2.5.7 (a) to (d) and BRCGS Issue 9 clause 4.11.8, and the Codex guideline they point to, and the risk assessment you generate is written in the structure auditors are used to seeing. It is not a clause by clause course on one scheme, so read your own standard alongside it.
