SUMMARY
The following sentences
From the multivariable analysis, V. parahaemolyticus infections were associated with antibiotics taken during the 4 weeks prior to illness [odds ratio (OR) 8·1, 95% confidence interval (CI) 1·2–56·4)], frequent eating out (OR 3·3, 95% CI 1·1–10·1), and shellfish consumption (OR 3·2, 95% CI 1·0–9·9), with population-attributable fractions of 0·09, 0·25, and 0·14, respectively. Protective factors included keeping the aquatic products refrigerated (OR 0·4, 95% CI 0·1–0·9) and pork consumption (OR 0·2, 95% CI 0·1–0·8).

From the multivariable analysis, V. parahaemolyticus infections were associated with antibiotics taken during the 4 weeks prior to illness [odds ratio (OR) 7·6, 95% confidence interval (CI) 1·1–54·4)], frequent eating out (OR 3·3, 95% CI 1·0–10·4), and shellfish consumption (OR 3·4, 95% CI 1·0–11·1), with population-attributable fractions of 0·09, 0·24, and 0·14, respectively. Protective factors included keeping the aquatic products refrigerated (OR 0·4, 95% CI 0·2–1·0) and pork consumption (OR 0·2, 95% CI 0·1–0·9).

Data collected included demographics; pre-existing illness; previous medication use; travel history (travel to other city/province); animal contact; refrigeration of certain aquatic products (i.e. fish, shrimp, crab and shellfish, whether of freshwater or saltwater origin) at home; other family kitchen practices; food consumption; meals eaten outside of home; and drinking water source.

In August, case-patients were four times more likely to eat shellfish compared to controls (OR 4·0, 95% CI 1·2–13·3). However, no association was observed between illness and shellfish consumption in other months (OR 2·0, 95% CI 0·4–9·9).

In August, case-patients were five times more likely to eat shellfish compared to controls (OR 5·3, 95% CI 1·4–20·1). However, no association was observed between illness and shellfish consumption in other months (OR 1·5, 95% CI 0·3–6·7).

We found that cleaning kitchen counters with dishwashing liquid or detergent was more frequently reported by controls than by cases, although it did not reach statistical significance (64·8% vs. 56·3%; OR 0·6, 95% CI 0·3–1·1).

In the final multivariable model, antibiotics taken in the 4 weeks prior to illness (OR 8·1, 95% CI 1·2–56·4), eating out ≥3 times (OR 3·3, 95% CI 1·1–10·1), and shellfish consumption (OR 3·2, 95% CI 1·0–9·9) were independent factors associated with an increased risk for illness (Table 4). Keeping the aquatic products refrigerated (OR 0·4, 95% CI 0·1–0·9) and pork consumption (OR 0·2, 95% CI 0·1–0·8) were independent factors associated with a reduced risk for infection. There was no association between eating poultry other than chicken in the 5 days before illness or interview and V. parahaemolyticus infection (OR 0·5, 95% CI 0·2–1·0) after adjusting for other risk factors.
