Mr. Chair, members of the committee, my name is Robert Charlebois, and I am the Executive Director of Food Safety and Consumer Protection at the Canadian Food Inspection Agency.
I just want to take a few minutes to explain to the committee what fusarium toxins are and why we test for them. I will also let you know what the allowable limits are for these toxins as there are different thresholds depending on what the end product is to be used for. Finally, I will try briefly to bring some clarity to the recent report in La Presse about grain being rejected in Prince Edward Island.
Deoxynivalenol, or DON, commonly referred to as vomitoxin, is a toxin, as we heard, that may occur in a variety of grains--wheat, for sure, but barley, oats, rye, and maize. It could develop in humid and warm conditions during the flowering season.
Health Canada, as we just heard, sets the standard for food safety in Canada, so they have set the allowable threshold for these toxins in food. Current guidelines permit a maximum of two parts per million of vomitoxin or DON in uncleaned soft wheat. So that's the current guideline set by Health Canada. That type of soft wheat is used for the manufacture of food products such as cake, cookies, biscuits, and cereals.
The threshold for using infant food, however, is lower, at one part per million. These standards have been in place for more than 20 years and have not changed recently.
For grain intended for feed, this is a bit different: CFIA sets the level. Current action levels for vomitoxins are at one part per million in complete feed for the diets of swine, young calves, and lactating dairy animals, and five parts per million in complete feed for cattle and poultry because they are more resistant. These standards have not changed for over a decade as well.
Levels of these toxins are monitored by the CFIA because they can cause serious health problems in humans and animals when ingested, even at very low levels, specifically, parts per billion to parts per million. In humans, DON and other mycotoxins can cause nausea, vomiting, diarrhea, abdominal pain, severe hemorrhaging, immune suppression and even cancer. The effects on livestock can include feed refusal, vomiting, impaired reproductive function, reduced fertility, lung disease, cancer and, in some cases, even death.
The CFIA conducts targeted inspections and sampling at the milling level if the grain is intended for human consumption. Compliance levels are typically high. For feed, the CFIA has tested for these types of toxins and mycotoxins for many years, including random and targeted sampling.
I have been describing the regulatory limits for these toxins and inspector programs for soft wheat. For hard wheat, Health Canada has not yet established a regulatory standard or limit for the presence of DON or vomitoxin. Thus, the levels of 2 ppm and 1 ppm are for soft wheat.
Given the potential health risk of vomitoxin, the CFIA is conducting monitoring, albeit limited, for this contaminant in hard wheat. This is done in accordance with section 4 of the Food and Drugs Act, which presents a general prohibition on the sale of unsafe food. Even where no specific standard or guideline has been established by Health Canada, section 4 of the Food and Drugs Act must be taken into account.
Where vomitoxin is present in a sample, these results are submitted to Health Canada for a health risk assessment. Based on that assessment, CFIA will consider enforcement action--where warranted only, for sure. That is the general approach that we're using.
To go back to the P.E.I. issue, recently some articles were published in the media that CFIA had suddenly changed the threshold for these toxins. This is not accurate. As I mentioned earlier, the standard for food is not set by CFIA. The soft wheat standard is established by Health Canada and it has not changed. Nor did CFIA change the allowable limits for these toxins in animal feed. We have not been engaged in any recent enforcement actions related to this risk in Prince Edward Island.
I also want to make it clear that, contrary to media reports, CFIA did not instruct mills to refuse wheat from P.E.I. farmers. The more recent report suggests there was a miscommunication from the wheat buyer that led producers to believe they would have to meet higher or altered standards than the ones set by Health Canada or the CFIA in the case of feed. The error was acknowledged at a later date.
The Canadian government's policies around vomitoxin are all established in the international context of shared sound science. Canada actively participates in the work done by the Codex Alimentarius Commission on additives and contaminants, which puts a focus on vomitoxin.
This body is responsible for developing the code of practice for the prevention of mycotoxin contamination in cereals. The Codex Alimentarius Commission is an international body established under the joint auspices of the Food and Agriculture Organization of the United Nations and the World Health Organization. It develops food standards, international guidelines and texts, such as the code of practice I just mentioned.
Canada's participation in such bodies is consistent with the high priority the Government of Canada places on protecting the health of consumers. Monitoring for vomitoxin is an important element of our overall food safety program.
Thank you, Mr. Chair.
I would be happy to answer any questions the committee may have for me.
